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.
