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 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 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.
