Industrial air coolers provide efficient cooling solutions in large factories and warehouses, where machinery operation generates excessive heat. Their ability to lower temperatures effectively without requiring refrigerants makes them a practical choice for enhancing worker comfort and productivity.
Perfect for covered outdoor spaces, these coolers deliver refreshing airflow to keep guests and staff comfortable during hot days. Their mobility and quick installation make them a great choice for temporary event setups.
In agricultural settings, maintaining a comfortable environment for both workers and animals is crucial for animal welfare and productivity. Our swamp coolers help reduce heat stress in livestock barns and farm facilities, promoting healthier conditions.
Portable air coolers can enhance the dining and shopping experience by keeping indoor and outdoor areas cool during hot weather. This not only attracts more customers but also improves comfort for staff.
Greenhouses benefit from cooler air to support healthy plant growth. Our air coolers help lower air temperature, creating a more comfortable climate for plants while being energy-efficient and cost-effective.
Whether in aviation hangars, automotive workshops, or logistics centers, evaporative air coolers can manage temperature in expansive areas where traditional air conditioning may not be feasible.
Our products are effective industrial air conditioners for factories, warehouses, and assembly lines where temperature and humidity control are essential.
Critical for spot cooling sensitive equipment to prevent overheating and maintain operational reliability.
These air conditioner units are excellent for quick deployment during HVAC breakdowns or extreme weather conditions. They offer extra cooling or heating.
Control air quality and temperatures easily to secure conditions and processes at your construction site. A portable air conditioner without an outdoor unit is easy to move and use.
Perfect for wood- or metalworking spaces, and other workshops where spot cooling is needed to keep workers comfortable and focused.
Ideal for maintaining optimal conditions in storage areas, greenhouses, or livestock enclosures.
Rex Nordic evaporative coolers lower the ambient temperature by 4°C to 12°C when outdoor temperatures exceed 22°C. The actual temperature drop depends on the ambient humidity — the lower the humidity, the greater the cooling effect.
Evaporative air coolers slightly increase the humidity of the air, but they do not produce mist or excessive moisture. To prevent humidity build-up in the space, ensure proper ventilation by keeping doors and windows open to allow fresh air circulation.
Yes. Rex Nordic evaporative coolers are well suited for dusty environments. The cooling pads act as natural air filters, trapping dust particles while simultaneously cooling the air. This makes them ideal for workshops, warehouses, and production facilities.
No. The Rex Nordic evaporative air cooler range does not have WiFi connectivity. They are operated via the on-unit control panel or remote control (model dependent).
No fixed installation is required. Rex Nordic evaporative coolers are plug-and-play units — simply connect the power cord, fill the water tank or connect to a water supply, and switch on. They can be repositioned as needed.
Yes. In addition to manually filling the built-in water tank, the coolers can be connected to a continuous water supply such as a garden hose via the inlet connector. This eliminates the need to refill the tank during long operating periods.
Maximum power consumption (±10%): REX 14000: 510 W/h | REX 25000: 850 W/h | REX 48000: 1,100 W/h
These figures are significantly lower than conventional air conditioning systems, making evaporative cooling an energy-efficient choice.
Water consumption varies by model and operating conditions, typically between 7.5 L and 37 L per hour. A fully filled tank generally provides a complete 8-hour working day of operation without refilling.
Yes. Rex Nordic evaporative coolers feature a built-in 40 W UVC light system that sterilises the circulating water, killing bacteria and viruses and ensuring the air output remains hygienic.
Cooling pads typically last 2–4 years in normal environments. In heavy-duty or dusty industrial settings, replacement is recommended every 1–2 years. Spare pads are available through Rex Nordic warehouses and authorised dealers.
Maintenance requirements are minimal. Regular light flushing of the water system and periodic replacement of the cooling pads is all that is normally needed. Easy-access panels simplify cleaning and servicing.
All Rex Nordic evaporative coolers come with a standard 2-year warranty. Register your product at warranty.rexnordic.com within four weeks of purchase to extend coverage to 3 years at no extra cost.
Rex Nordic mobile air conditioners use a vapour-compression refrigeration cycle. A refrigerant absorbs heat from the indoor air, transfers it to the condenser, and expels it outdoors via an exhaust hose. The cooled air is recirculated back into the space. Models in the HP series feature spot-cooling capability for targeted industrial applications.
Rex Nordic mobile air conditioners can cool the supply air by approximately 10°C relative to the inlet air temperature. For effective room cooling, ensure the hot air exhaust hose is routed to the outside. In spot-cooling applications, directing cool air at specific equipment or workstations, the effective temperature reduction can be even more pronounced.
No. Our mobile air conditioners are portable and require no permanent installation. They can be moved between locations as needed. The exhaust hose must be routed to an outside opening, window kit, or ceiling void. Installation kits are available as accessories.
The correct unit size depends on the dimensions of the space, insulation quality, heat load from equipment, and number of occupants. Rex Nordic offers a free site assessment service — contact our sales team who can recommend the right model for your application.
Regular cleaning of the air filter is recommended, approximately every 2 weeks in continuous operation. Periodically check the condensate drain — most models include a self-evaporating condenser so manual drainage is not usually required. Full service by an authorised technician is recommended annually for heavy commercial use.
All Rex Nordic mobile air conditioners carry a standard 2-year warranty. Register at warranty.rexnordic.com within four weeks of purchase to extend the warranty to 3 years at no cost.
