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. It provides cooling, heating, air purification, and dehumidification in one robust unit. Key features include: Durable steel Easy to move with wheels and handles Operates from a standard 230 V outlet – no installation required Compact size, approx. 80–90 kg Delivers up to 15°C cooling in the target zone Simultaneously filters dust and harmful vapors from the air Cool Air Exactly Where You Need It The HP-19 can be positioned close to heat-intensive work areas, with airflow directed precisely using adjustable nozzles or optional flexible ducts. A 10-meter duct, for example, can channel cool air directly to a welder’s workstation or a specific piece of equipment, without wasting cooling power across the hall. What about the hot exhaust air? HP-19 works like a powerful air conditioner: it draws in warm air, cools it, and blows out cool air from the front, while warm exhaust air is released from the rear. The unit can be used with or without an exhaust hose. In smaller or enclosed areas, we recommend using the hose to vent hot air outdoors or upwards, away from the workspace, for optimal efficiency. In large, well-ventilated production halls, HP-19 can be used without a hose – the heat disperses widely and doesn’t interfere with local cooling. Thanks to its flexibility, HP-19 is ready to use anywhere: position it, aim the airflow, and switch it on.

In this article: How heat affects precision machinery and compressors Why spot cooling is critical for uptime and performance Key features of the Rex Nordic HP-19 and HP-60 units The benefits of mobility, energy efficiency, and air quality control What can go wrong without proper cooling How spot cooling works: the technical edge In modern industrial environments, where precision and reliability are essential, the ability to manage heat around equipment is vital. From compressor rooms to CNC machines, controlling thermal loads ensures not only operational continuity but also product quality and component longevity. Industrial machinery, especially those operating within tight tolerance parameters, requires stable thermal conditions to avoid performance degradation. The Rex Nordic HP-19 and HP-60 air conditioners offer a dependable solution to these challenges with powerful industrial spot cooling. What can go wrong without proper cooling? Inadequate cooling in industrial environments can have a cascade of negative effects: Overheating can trigger system shutdowns or damage sensitive motors and drives. Expansion from thermal stress can misalign spindles or deform components. Increased wear on tools reduces service life and machining accuracy. Production rejects rise due to dimensional inconsistencies in workpieces. Uncontrolled humidity can lead to corrosion or condensation-related malfunctions. These risks underline why investing in a robust, portable cooling system is a preventive measure that pays off in equipment protection and production quality. Precision cooling for critical components Modern manufacturing demands tight tolerances, often in the micrometer range. Even minor heat fluctuations in motors, spindles, or tool housings can lead to expansion or contraction that compromises performance. The Rex Nordic HP-19 and HP-60 units deliver targeted spot cooling directly to heat-sensitive machinery components, helping to prevent thermal drift and ensuring dimensional stability during operation. This machinery overheating prevention is particularly beneficial in confined compressor rooms, where heat generated from constant operation can quickly accumulate.

Designed for demanding industrial conditions With capacities of 5.6 kW and 17.5 kW respectively, the HP-19 and HP-60 support air volumes up to 2117 m³/h. This level of cooling is indispensable for precision machinery where excessive heat can lead to axial expansion, spindle misalignment, or reduced cutting accuracy. They also manage humidity effectively, which is critical in preventing condensation that can impact electronic controls and sensitive components. The ability to remove up to 197 liters of moisture per day makes them suitable even for moisture-intensive industrial zones. How spot cooling works Spot cooling is a technique that focuses cooled air precisely at heat sources such as motors, compressors, or CNC spindles, instead of cooling the entire space. This is done using ducted airflow, which minimizes energy use while maximizing temperature control at critical points. It is especially effective in industrial environments where localized overheating affects only part of the system. Rex Nordic units can be ducted and repositioned as needed, giving operators flexibility to adapt to layout or equipment changes. Adaptable and portable for evolving industrial needs As production setups shift and expand, so do cooling requirements.
