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. Its larger sibling, the HP-60, offers even more power for bigger areas, but for many mid-sized workshops and welding stations, the HP-19 hits the sweet spot between performance, portability, and cost.

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. 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
