A Portable Air Conditioner Solved a Laundry’s Heat Challenge
In brief In laundries, heat tends to concentrate at specific workstations such as sheet ironers, tumble dryers and pressing equipment, where large amounts of heat are generated. In a UK-based laundry, temperatures in the hottest areas rose to well over +40 °C, placing significant strain on employees. The HP-19 (19,000 BTU) portable air conditioner enabled precise, targeted cooling combined with effective dehumidification. WHO and ILO emphasise the importance of targeted cooling solutions in managing heat in hot indoor working environments. Laundries are not usually thought of as hot workplaces, yet in reality they can be surprisingly demanding, especially during the summer months. In a professional laundry in the United Kingdom, heat built up around the sheet ironers, tumble dryers and pressing area, where temperatures during peak periods rose clearly above +40 °C. The heat did not spread evenly throughout the facility but accumulated at these specific workstations. This had a direct impact on employee comfort and endurance. To address the issue, the site selected the Rex Nordic HP-19 portable air conditioner, allowing cooling to be focused precisely where the heat was felt most intensely. Heat challenges in laundries originate from machinery The heat generated in laundries is a direct result of the machinery used in daily processes. Sheet ironers, tumble dryers, pressing and other finishing equipment continuously produce large amounts of heat as wet textiles are dried, ironed and finished. This heat is released directly into the workspace—often exactly where employees spend long periods working next to the machines. As a result, heat does not distribute evenly across the entire laundry but concentrates at certain workstations. International studies show that in such environments, employees are exposed to heat stress, which can reduce stamina, concentration and physical performance. The U.S. Occupational Safety and Health Administration (OSHA) recognises laundries as workplaces where localised heat can increase fatigue and accident risk unless heat loads are actively managed and cooling is properly targeted. High temperatures also place additional strain on machinery. A more stable and cooler operating environment supports equipment durability, reduces maintenance needs and lowers the risk of unplanned production downtime. In this way, cooling benefits both employee working conditions and overall operational reliability. Targeted cooling in practice: a 19,000 BTU air conditioner in laundry use The HP-19 is a refrigerant-based portable air conditioner with a cooling capacity of 19,000 BTU per hour, equivalent to approximately 5,570 watts. The BTU value indicates the unit’s ability to remove heat energy from the air: the higher the rating, the more heat the unit can transfer out of the space. In a laundry environment, where sheet ironers, tumble dryers and presses generate heat continuously, this level of capacity enables effective cooling even during prolonged operation. The HP-19 cools air using the same principle as fixed air conditioning systems. Thanks to the refrigerant circuit, temperature control is precise and reliable, rather than a short-term cooling effect. In cooling mode, the user can set a target temperature between 18 °C and 30 °C, and the unit automatically maintains the selected temperature even during heatwaves. The units were deployed on a workstation-specific basis: on both sides of the sheet ironer near the tumble dryers in the pressing area A key factor was also the air conditioner’s high dehumidification capacity, removing up to 118 litres of moisture per day. High humidity is typical in laundries and makes heat feel heavier and more exhausting. When moisture is controlled, heat is perceived as significantly more tolerable and working conditions improve—without the need to lower the temperature throughout the entire facility. The HP-19 can also be used to improve air quality through different filtration options. In laundry environments, this can reduce airborne dust and fibres, helping to improve indoor air quality and support employee working conditions. Why was cooling focused only on specific workstations Laundry facilities are often large, with continuous production processes. Although a portable air conditioner may be suitable for spaces of up to 550 m³, cooling an entire hall is not always the most practical solution if heat is generated locally around machinery. In such cases, a large portion of the cooling capacity would be directed to areas where heat is not the primary issue. In this case, cooling was deliberately targeted at the workstations with the highest heat load. This not only improved working conditions but was also an energy-efficient solution: by avoiding unnecessary cooling of the entire space, overall energy consumption remained significantly lower. The portable air conditioner made it possible to: deliver cooling directly to the employee’s working area reposition units flexibly according to production flow and workstation needs deploy the solution quickly, without structural modifications or production downtime This approach is in line with recommendations from the World Health Organization (WHO) and the International Labour Organization (ILO). Both organisations emphasise that in hot indoor working environments, heat exposure should primarily be managed through targeted technical solutions, especially at workstations where employees are exposed to heat for extended periods. Employee experience – less heat, a better working day Although the solution was technically simple, its impact on everyday work was clearly noticeable. Employee feedback was unanimous: the hottest workstations became manageable, and the working day felt lighter even during periods of high temperatures. Research shows that even a moderate reduction in temperature and humidity can improve concentration, reduce fatigue and increase job satisfaction. In this laundry, the improvement was quickly reflected in daily work and in employee experience. A portable air conditioner as part of a functional working environment The British laundry continues operating as before—but conditions at the hottest workstations are now clearly better. The portable air conditioner proved to be a practical solution in an environment where heat is generated by machinery rather than outdoor conditions. When cooling and dehumidification are correctly targeted, working conditions can be improved without major modifications to the facility. The HP-19 is particularly well-suited for professional use, targeted cooling and situations where a flexible, rapidly deployable solution is required.

Portable Air Cooling for Event Tents and Temporary Spaces
Summary Suitable for event tents, outdoor events, trade fairs and pop-up spaces Cooling capacity can be scaled according to the size of the space Can be implemented with multiple smaller units or by combining different unit sizes Can also be used as a fan, but the most efficient cooling is achieved with water Units can be connected directly to a water supply or operated using the internal water tank Temporary event spaces often present challenges in warm weather conditions. Event tents, exhibition stands, outdoor sales areas and pop-up environments can heat up quickly in direct sunlight, and traditional air conditioning is usually not a viable option in these types of spaces. What is needed instead is a portable solution, quick to deploy and powerful enough to work in open or semi-open environments. Rex Nordic air coolers are designed to efficiently cool large areas, with minimal effort and no permanent installation required. The smallest model cools areas up to 120 m², the mid-size model up to 250 m², and the largest model up to 500 m². The cooling solution can be scaled to different room sizes either by using multiple smaller units or by combining models of different capacities within the same space. Sizing the Cooling Solution for Event Environments In event spaces, cooling is typically most effective when implemented in one of the following ways: with several smaller units, when the space includes multiple activity areas or structures that affect airflow with larger-capacity units, when the space is open, high-ceilinged or hall-like The objective is not to chill a sealed indoor environment, but to improve temperature conditions and airflow across a wide area, helping guests and staff remain comfortable for longer and ensuring a pleasant experience even in hot weather. Evaporative Cooling Performance Is Based on Water Rex Nordic air coolers can be used as high-performance fans, but the best cooling efficiency is achieved when the unit operates using evaporative cooling with water. Water supply can be arranged in two ways: the unit can be connected directly to a water line, enabling continuous operation or water can be added manually to the unit’s internal water tank The system does not require refrigerants or fixed installation, which makes the coolers ideal for temporary and mobile environments. Typical Use Cases During summer and early autumn, Rex Nordic air coolers are commonly used in: event tents and private celebrations corporate events and customer days trade fair and exhibition stands food-service and catering areas backstage and staff working areas A key advantage is that the same unit can easily be moved from one location to another and reused across multiple events. Case: Flexible Cooling in a Summer Wedding Tent Using Two REX14000 Units A large outdoor summer wedding was held in a 200 m² event tent, including a full seating area, dance floor and a high number of guests. Due to lighting, activity and crowd density, the temperature inside the tent was expected to rise to an uncomfortable level as the evening progressed. Instead of relying on a single larger unit, the organiser chose to install two REX14000 air coolers. Each unit is capable of cooling up to 120 m², making the combined capacity well-suited for the tent size. The units were positioned on opposite sides of the tent, allowing airflow to cross the space evenly and creating more consistent cooling throughout the venue. Cooling was implemented by connecting both units directly to a water supply, ensuring stable performance during the entire event. While a single REX25000 could technically have handled a tent of this size, using two smaller units allowed better airflow control, more flexible placement and more even cooling distribution across different activity zones within the tent. During the evening, the tent remained pleasantly cool, guests stayed inside longer and the dance floor remained in active use. Feedback highlighted improved comfort and a more enjoyable atmosphere, leading the organiser to decide to use the same setup for future events. Portable Cooling for Events – A Practical Solution for Temporary Spaces Temporary event venues are always a balance between flexibility, usability and environmental conditions. A solution that can be moved, scaled to the space and deployed quickly provides a practical way to improve event comfort without heavy infrastructure. Rex Nordic air coolers — REX14000, REX25000 and REX48000 — are designed precisely for these environments: they deliver comfortable conditions in large spaces when the event is temporary, but the experience still needs to feel consistently high-quality for every guest.
HP-19 – Targeted Cooling for the Metal Industry’s Hottest Workstations
Workstations in the metal industry, such as welding and plasma cutting areas, generate intense heat. This excess warmth can impair concentration, reduce stamina, and increase the risk of equipment overheating. Traditional hall-wide cooling systems or fans often fail to focus air where it’s most needed. The Rex Nordic HP-19 portable air conditioner solves this problem with efficient, targeted cooling, delivering relief exactly where thermal stress is highest. Effective Cooling for Welding and Cutting Stations Welding and plasma cutting can rapidly raise temperatures to uncomfortable levels. General air conditioning often isn’t enough to cool the immediate workspace, where glowing metal and arc radiation generate significant heat. With the HP-19, cool airflow is directed right to the hot zone, improving comfort and safety around the worker or machine, without needing to overcool the entire facility. Mobile Cooling Power – No Installation Required The Rex Nordic HP-19 is a mobile 4-in-1 air conditioner designed for demanding industrial environments.

Airrex diesel heater – steady warmth and real savings
Good heating isn’t just about power. It’s also about cost efficiency – directing warmth exactly where it’s needed. Airrex diesel infrared heaters have proven in practice that consistent comfort doesn’t require high fuel consumption. The following examples show how Airrex heaters have helped keep heating costs in large industrial spaces under control – without compromising comfort. Proven results with infrared heating: only 2.5 litres per day Many are surprised to learn how little fuel Airrex diesel heaters actually consume. They’re designed to heat spaces effectively and evenly, without wasting energy where it isn’t needed. Grels Ström, a retired technical expert from Rex Nordic, uses an Airrex heater in his 480 m³ warehouse. The building has mineral wool insulation in the ceiling, plasterboard walls, and a concrete floor – a structure that stores heat efficiently. Previously, the warehouse was heated with direct electric heating, but switching to diesel brought a clear drop in both consumption and costs. Ström explains his experience: “At first, fuel consumption can be slightly higher. It usually takes about a week or a week and a half before it stabilises. Infrared heat is absorbed directly into the structures, and once they’re fully warmed, surprisingly little fuel is needed to maintain the temperature.” He keeps the warehouse at +15 °C when it’s around zero outside and has achieved remarkably low fuel consumption. Once the building is fully warm, daily consumption averages only about 2.5 litres of diesel. The Airrex heater has run reliably without problems and has required almost no maintenance. A slightly higher initial consumption is normal since building materials often contain moisture that must first dry out. Once dry, the system reaches its optimal efficiency. This is where Airrex infrared technology truly shines. The heat is stored within the structures and stays there. After that, only short heating cycles are needed to maintain a pleasant temperature day after day – and the savings show directly on the fuel bill. Smart thermostat keeps consumption low Every Airrex infrared heater comes with a built-in thermostat that helps minimise fuel consumption. The heater starts and stops automatically to maintain the desired temperature. Diesel is burned only when needed – and it’s metered precisely, no more than necessary, keeping consumption to a minimum. In practice, this means the heater works independently. Once the building’s structures have warmed up, the unit maintains the temperature with short operating intervals. There’s no need for constant adjustments – the thermostat does the work for you. Unlike traditional air-blowing heaters, Airrex units don’t push hot air to the ceiling or out the door when it’s opened. Infrared heat is directed straight into walls, floors, and machinery, which absorb and store it. As these structures retain heat, energy use remains exceptionally low. If a door is opened, the stored warmth quickly restores the indoor temperature. Long-term savings with Airrex diesel heaters Markku Ojanen has seen the difference first-hand. He heats a 1,080 m³ (360 m², 3 m high) insulated hall, which used to rely on radiators and fan heaters. The previous system consumed around 2,500 litres of oil per year. After installing an Airrex AH-300 diesel heater, the improvement was immediate. In the first winter alone, annual fuel use dropped to about 1,000 litres – less than half of the previous amount. He keeps the hall at a steady +9–10 °C, raising it to +13 °C while working. Over ten years of use, the savings have amounted to roughly €10,000–11,000, and the same heater continues to operate flawlessly. “Maintenance has been done on time, but no repairs have ever been needed,” Ojanen says. “It just keeps going.” Sustainable warmth you can feel Airrex infrared heating works on a simple yet powerful principle: instead of heating air, it radiates warmth directly into surrounding surfaces. Floors, walls, and objects absorb the heat – just like sunlight warms your skin. Once these surfaces are warm, they release heat evenly back into the air, maintaining a consistent indoor temperature. This stored warmth acts as a natural heat buffer, keeping fuel consumption low after the first weeks. The heater runs only as much as needed to maintain balance. That’s the key difference between infrared and traditional fan heaters. Infrared heat doesn’t escape when doors open or air circulates. The stored warmth in the structures quickly restores the temperature, keeping the heat where it’s needed and the savings ongoing. Site 1 – Warehouse Type: Warehouse 480 m³ Structure: Concrete floor, ceiling insulation, plasterboard walls Previous heating: Direct electric New solution: Airrex diesel infrared heater Maintained temperature: +15 °C in around 0 °C outdoor conditions Average daily fuel consumption: ~2.5 L diesel Maintenance: Reliable operation, almost no maintenance required Savings: Significantly lower consumption than the previous system Site 2 – Industrial hall Type: Insulated hall 1 080 m³ (360 m², 3 m height) Previous system: Radiators + fan heaters Previous fuel use: ~2,500 L oil/year New solution: Airrex AH-300 diesel heater Current fuel use: ~1,000 L/year Usage time: 10 years Estimated savings over 10 years: ~€10,000–11,000 Reliability: Same heater still running flawlessly, no repairs needed

Their advantages include energy efficiency and environmental friendliness compared to traditional air conditioning systems. This article examines the operating principle, applications, and benefits of evaporative coolers, as well as the technical aspects to consider when using them. Operating Principle of Evaporative Coolers Evaporative coolers utilize the evaporation process of water to cool the air effectively. This is based on a physical phenomenon where water evaporates and absorbs heat energy from the surrounding air, leading to a decrease in air temperature. Humidification and Heat Transfer Water evaporates when exposed to an airstream, and this process absorbs heat from the air, cooling it down. Coolers use special pads designed to maximize the surface area for water evaporation. These pads are often made of cellulose or plastic, which are hygroscopic and provide a large evaporative surface. Air flows through the pads via a fan, where it encounters water. The water evaporates, absorbing heat energy from the air, thus cooling it. Energy Consumption and Efficiency The energy consumption of evaporative coolers is significantly lower compared to traditional mechanical cooling systems because the process uses natural water evaporation and does not require substantial amounts of electrical energy. The efficiency of these systems depends on the ambient temperature and humidity. They work best in dry and hot conditions where the air’s moisture content is low, as this makes water evaporation most efficient. Operational Principle Adiabatic Cooling: Air is cooled through an adiabatic process where its temperature drops as it becomes humidified. This means that the air’s thermal energy is used for water evaporation without an external energy source. Ventilation and Pressure: In the cooler, air passes through the pads via a fan. The air flowing through the pads encounters moisture that evaporates and cools the air. The fan’s role is critical as it ensures sufficient airflow through the pads and guarantees uniform cooling. Water Circulation: In evaporative coolers, water circulates continuously. Water is pumped to the top of the pads, from where it flows down and evaporates due to the airstream. The recirculation system ensures even water distribution and optimizes the cooling process. Applications in Professional Use Evaporative coolers are widely used across various industries and other large-space cooling applications where efficient and cost-effective cooling is needed. Industrial Facilities Metal Industry: In hot factory halls where temperatures can rise extremely high, evaporative coolers provide an efficient cooling solution that helps keep the working environment tolerable and safe. Automotive Industry: Assembly lines and paint shops in car factories benefit from a cooler working environment, which improves worker efficiency and reduces errors. Food Industry: Evaporative coolers are ideal for cooling large storage and production areas where temperature control is critical to maintaining product quality. Data Centers Data centers require continuous and efficient cooling to prevent equipment from overheating. Evaporative coolers offer an energy-efficient alternative that can significantly reduce cooling costs in data centers. Using adiabatic cooling, data centers can also reduce their carbon footprint, which is increasingly important as environmental regulations tighten. Agriculture Greenhouses: Evaporative coolers help maintain optimal growing conditions, improving crop yields and growth rates. Cooler air reduces plant stress and enhances their resistance to diseases. Animal Shelters: Animal welfare improves in cooler conditions, leading to better health and productivity. This is especially important during the summer months when heat stress can negatively affect animal well-being. Advantages and Challenges Evaporative coolers offer many advantages. Advantages Energy Efficiency: Evaporative coolers use significantly less electrical energy compared to traditional cooling systems because they rely on the natural evaporation process. Environmental Friendliness: Since the system only uses water and air for cooling, its environmental impact is minimal, and the carbon footprint is small. This makes them an attractive option for organizations aiming to reduce their environmental impact. Cost Savings: Lower energy consumption and simple technology mean lower operating and maintenance costs compared to complex mechanical cooling systems. Technical Considerations and Design Portable evaporative coolers are highly convenient and flexible solutions for various professional cooling needs. Their technical design and use require special attention to the following aspects: Components and Materials Pads: The pads are the central part of the cooler responsible for water evaporation. They are often made of cellulose or plastic, providing a large evaporative surface and withstanding moisture and mechanical wear. Fans: Powerful fans ensure sufficient airflow through the pads. The performance of the fans directly affects the efficiency of the cooler. Water Systems: Water systems pump water to the top of the pads, from where it flows down and evaporates due to the airstream. The systems include filters and pumps that ensure water circulation and cleanliness. Device Placement Airflow Control: Optimal airflow and ventilation are essential to maximize cooling. Portable coolers should be placed to draw in as much dry and hot air as possible for the most effective evaporation. Water Source and Quality: A clean and adequate water source is vital for the system’s operation and longevity. Water quality affects the durability and efficiency of the pads and water systems. Considering Portability Durable Construction: Portable evaporative coolers must be durable and sturdy enough to be easily moved to different locations. This means strong frame materials and well-protected components. Practical Wheels: Large wheels enable easy movement of the device and are designed to withstand various floor materials and surfaces. Easy Connectivity: Coolers are easy to connect to electrical and water sources in different locations. They have practical connections and sufficiently long cables and hoses. Impact of UV Light UV light is used in evaporative coolers to improve water quality and prevent bacterial growth. Water Disinfection: UV light kills microorganisms and bacteria in the water, reducing biofilm and slime formation on the pads. This improves the system’s hygiene and reduces maintenance needs. Pad Cleanliness: UV light helps keep the pads free from biological impurities, enhancing their evaporative efficiency and extending their lifespan. Cost Savings: Using UV light reduces the need for chemical cleaning agents and improves the system’s
