Portable air conditioning solved laundry heat issues
In brief In commercial laundries, heat often builds up around specific workstations, such as sheet ironers, tumble dryers, and pressing stations, where equipment generates significant heat. At a laundry facility in the UK, temperatures in the hottest areas exceeded +40 °C, creating difficult working conditions for staff. The HP-19 portable air conditioner (19,000 BTU) provided targeted cooling exactly where it was needed, while also effectively reducing humidity. Organisations such as the WHO and ILO highlight targeted cooling as an important way to manage heat in demanding indoor workplaces. Laundry facilities are rarely considered particularly hot working environments, yet in practice they can become extremely demanding—especially during warmer periods of the year. At a professional laundry operation in the United Kingdom, heat accumulated around the sheet ironers, tumble dryers and pressing stations, where peak temperatures regularly rose beyond +40 °C. Rather than spreading evenly across the facility, the heat remained concentrated around these individual workstations. This significantly affected employee comfort and endurance during busy periods. To improve the situation, the site introduced the Rex Nordic HP-19 portable air conditioner, allowing cooling to be directed precisely to the areas with the highest heat exposure. Laundry heat loads are mainly caused by machinery The primary source of heat in laundries is the machinery used in daily operations. Sheet ironers, tumble dryers, presses and other finishing equipment constantly release heat as wet textiles are dried, pressed and prepared for use. Much of this heat is emitted directly into the surrounding workspace—often exactly where employees are positioned throughout their shift. As a result, temperature levels in laundries typically vary depending on the workstation. Rather than affecting the entire building equally, heat tends to build up around certain machines. Research indicates that employees working in these conditions may experience heat stress, which can affect concentration, stamina and physical performance. The U.S. Occupational Safety and Health Administration (OSHA) identifies laundries as environments where localised heat can increase fatigue and accident risk if temperatures are not actively controlled. Excessive heat can also affect equipment. A cooler and more stable operating environment helps extend machinery lifespan, lowers maintenance requirements and reduces the likelihood of unexpected production interruptions. In this way, cooling improves both employee well-being and operational reliability. Targeted cooling in practice: a 19,000 BTU solution for laundry environments The HP-19 is a portable air conditioner with a cooling using a refrigerant cooling system, delivering a cooling capacity of 19,000 BTU per hour, equivalent to roughly 5,570 watts. The BTU rating reflects how much heat the unit can remove from the air: the higher the figure, the more effectively heat can be transferred out of the space. In laundries, where sheet ironers, dryers and presses generate constant heat, this capacity allows the system to maintain effective cooling even during extended operation. The HP-19 cools air using the same refrigeration principle as fixed air-conditioning systems. Because of the closed refrigerant circuit, the temperature can be controlled precisely and maintained consistently rather than providing only a temporary cooling effect. Users can set a desired temperature between 18 °C and 30 °C, and the unit automatically maintains that level—even during periods of very hot weather. In this installation, the units were positioned specifically where heat was generated: on both sides of the sheet ironer close to the tumble dryers within the pressing area Another important feature was the system’s strong dehumidification capability, removing up to 118 litres of moisture per day. Laundry facilities typically have high humidity levels, which can make heat feel significantly more uncomfortable. By reducing moisture in the air, the working environment becomes noticeably more tolerable without needing to cool the entire building. The HP-19 can also contribute to improved air quality through different filtration options. In laundry environments, this can help reduce airborne lint and fibres, supporting better indoor air conditions for employees. Why cooling was focused on individual workstations Laundry plants are often large spaces with continuous workflows. Although a portable air conditioner can be suitable for rooms up to approximately 550 m³, cooling an entire hall is not always the most efficient approach when heat is produced locally around machinery. In such cases, a considerable portion of the cooling capacity would be wasted on areas that are not affected by heat. For this reason, the cooling strategy was intentionally directed towards the workstations with the greatest heat load. This approach improved working conditions while also keeping energy use under control. By cooling only the necessary areas, the overall power consumption remained significantly lower. The portable system made it possible to: deliver cooling directly to the employee’s workstation move units easily as production layouts or needs change install the solution quickly without structural alterations or production downtime This strategy aligns with guidance from the World Health Organization (WHO) and the International Labour Organization (ILO). Both organisations recommend targeted technical measures to reduce heat exposure in indoor workplaces, particularly in areas where employees are exposed to elevated temperatures for extended periods. Employee feedback – cooler conditions, easier workdays Although the solution itself was straightforward, its impact on day-to-day work was clear. Employees reported that the hottest workstations became far more manageable, and shifts felt noticeably less exhausting even during warmer conditions. Studies indicate that even modest reductions in temperature and humidity can improve focus, reduce fatigue and support better overall job satisfaction. In this case, the benefits were quickly reflected in daily operations and staff experience. Portable air conditioning as part of a practical workplace solution The laundry facility continues to operate as before, but the environment around its hottest workstations has improved considerably. The portable air conditioner proved to be a practical option in a setting where heat is generated mainly by machinery rather than outdoor temperatures. When cooling and dehumidification are applied in a targeted way, it is possible to improve working conditions without major structural changes to the facility. The HP-19 is particularly suited for professional environments where flexible, quickly deployable cooling solutions are required. More information about the HP-19 portable air conditioner.

Cooling the Hottest Corners of Metalwork with HP-19 Mobile Air Conditioner
In the heart of any metalworking facility, heat is part of the job. Whether it’s arc welding, plasma cutting, or grinding, these tasks generate intense, localised heat, far beyond what general ventilation systems can handle. And while full-hall cooling might seem like a solution, it often proves wasteful and ineffective when the real challenge lies in just a few critical hotspots. That’s why many metal industry professionals are turning to targeted, mobile cooling, and specifically to the Rex Nordic HP-19. When General Cooling Falls Short Walk into any busy fabrication shop in summer and you’ll feel it immediately: the sharp contrast between the air near the ceiling fans and the sweltering temperatures next to a welding torch. High temperatures not only affect worker comfort and focus but also put sensitive equipment at risk. And yet, retrofitting a full AC system is costly, slow, and often unnecessary for the rest of the hall. The HP-19 approaches the problem differently. It’s not designed to cool an entire building, just the places where people and machines need it most. With a compact footprint, wheels for easy movement, and a powerful internal compressor, it delivers cold air exactly where it’s aimed – no ductwork or installation required. Cooling with Precision One of the most important features of the HP-19 is its ability to focus airflow directly at a workstation. Operators can position the unit within a few metres of a welder, plasma cutter, or CNC machine and direct the cool air precisely with built-in nozzles or optional ducting. In practice, this can lower the ambient temperature around the operator by up to 15°C – enough to make a real difference in concentration, endurance, and safety. And unlike simple fans, this unit actually conditions the air, removing heat and filtering it in the process. Built for the Realities of Industry The HP-19 isn’t a plastic consumer product. It’s built for rough environments, with a steel casing, rugged wheels, and components designed for long operating hours. It connects to a standard 230 V socket and weighs around 85 kg, heavy enough to stay put, but light enough to move when needed. Inside, it’s a 4-in-1 machine: cooling, heating, dehumidifying, and purifying the air. This means it’s useful year-round, not just in peak summer. And thanks to its built-in filters, it also reduces smoke, metal dust, and other airborne particles, particularly important in welding bays where fumes are a constant concern. Efficiency That Pays Off At 5.6 kW of cooling capacity and only 2.3 kW of power consumption, the HP-19 is surprisingly energy-efficient. It uses a low-GWP refrigerant, making it a more environmentally responsible option than many traditional systems. Combined with its focused output, that means you’re not paying to cool empty space, just the work that’s actually happening. Adaptable to Any Workshop Exhaust air can be routed out of the space using a flexible hose or simply allowed to disperse if the building is well-ventilated. This makes the HP-19 incredibly flexible. There’s no installation delay, no major changes to infrastructure, and no need to overthink where it fits. You can plug it in and start cooling in minutes. It’s a straightforward answer to a complex industrial problem. Trusted by Industrial Operators Across Europe The HP-19 is part of the new-generation range based on the long-standing Airrex HSC series, a name already well known in construction and agricultural sectors.

Airrex diesel heater – lasting warmth and proven savings
Good heating isn’t just about raw power – it’s about efficiency, comfort, and control. Airrex diesel infrared heaters have proven that steady warmth doesn’t have to mean high running costs. The following real-world examples show how Airrex keeps large workshops, warehouses and industrial spaces warm throughout the winter – while keeping fuel use impressively low. Proven results with infrared heating: only 2.5 litres per day Many people are surprised to discover how little fuel Airrex diesel heaters actually use. They are designed to heat spaces evenly and efficiently, 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 ceiling insulation, plasterboard walls, and a concrete floor – a structure that holds heat extremely well. Previously, the space was heated with direct electric heating, but switching to diesel has cut both consumption and costs dramatically. Ström explains: “At first, fuel use can be a little higher. It usually takes about a week or so for consumption to settle. Infrared heat is absorbed directly into the structures, and once they’re properly warm, surprisingly little fuel is needed to keep the temperature steady.” He maintains an indoor temperature of +15 °C even when it’s around 0 °C outside, and daily fuel consumption averages just 2.5 litres of diesel. His Airrex heater has run reliably without any issues or need for servicing. A brief period of higher consumption at the start is perfectly normal – the building materials often contain moisture that needs to dry out first. Once they’re dry, the system reaches maximum efficiency. This is where Airrex infrared technology excels: the heat is stored in the structure and released steadily back into the space. After that, only short heating cycles are needed to maintain comfort – and the savings are clearly reflected in the fuel bill. Smart thermostat keeps consumption under control Every Airrex infrared heater is equipped with an intelligent built-in thermostat that keeps fuel use to a minimum. The unit starts and stops automatically to maintain the desired temperature. Diesel is metered precisely – only as much as needed and not a drop more – which keeps consumption extremely low. In everyday use, the heater runs independently. Once the building’s structures are warm, the unit maintains a steady temperature with short operating cycles. There’s no need for constant adjustment – the thermostat does it all automatically. Unlike traditional fan heaters, Airrex units don’t blow hot air towards the ceiling or outside when doors open. Infrared heat is directed straight into walls, floors, and machinery, which absorb and store the warmth. As a result, energy use stays exceptionally low, and if a door is opened, the stored heat quickly restores the indoor temperature. Long-term savings with Airrex diesel heaters Markku Ojanen has experienced the same results first-hand. He heats a 360 m² insulated hall, three metres high, which used to rely on radiators and fan heaters. The old system consumed around 2,500 litres of oil each year. After switching to an Airrex AH-300 diesel heater, the difference was immediate. In the first winter alone, fuel use dropped to about 1,000 litres per year – less than half of what it was before. He keeps the hall at +9–10 °C, raising it to +13 °C while working. Over ten years, the savings have totalled around £8,500–£9,000, and the same heater is still operating flawlessly today. “Maintenance has always been done on time, but it’s never needed a single repair,” Ojanen says. “It just keeps running.” Sustainable warmth you can feel Airrex infrared heating works on a simple but powerful principle: instead of heating air, it radiates warmth directly into surrounding surfaces. Floors, walls and equipment absorb the heat – just like sunlight warms your skin on a cool day. Once these surfaces are warm, they release the heat evenly back into the room, creating a consistent indoor temperature. This stored warmth acts as a natural heat buffer, which keeps fuel consumption low after the first weeks of use. The heater only runs as much as is needed to maintain the balance. That’s the key difference between infrared and traditional fan heaters. Infrared heat doesn’t escape when doors open or air moves. The stored heat within the structure quickly restores the temperature, keeping warmth where it’s needed and savings ongoing.

How Professional Evaporative Coolers Work?
Evaporative coolers are an essential part of modern cooling technology, especially in industrial and other large-space cooling applications. 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.

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
