Air Coolers
for Reliable Cooling in Large Spaces
Beat the heat with eco-friendly evaporative coolers
Rex Nordic’s mobile evaporative air coolers are designed to excel in challenging environments—from vast industrial sites to covered outdoor areas where traditional air conditioners simply can’t keep up. Unlike air conditioners, these air cooling fans require natural airflow or an existing ventilation system to function effectively, making them ideal for open spaces, industrial environments, warehouses, and events. They provide powerful, energy-efficient cooling for large spaces without the need for costly installations. In hot, dry conditions, they work at their best, while in humid environments, proper air circulation—such as open doors, windows, or air conditioning—ensures optimal performance.
Built for extreme working conditions, they lower temperatures by up to 12°C when outdoor heat exceeds 22°C, providing a refreshing alternative that cuts energy costs. With integrated UVC technology that sanitizes circulating water, these coolers not only improve air quality by eliminating germs and viruses but also create a healthier, more comfortable work environment.
Plus, all spare parts are readily available through our warehouses, and we offer comprehensive maintenance services to ensure that your air coolers continue to perform at their best. To provide additional peace of mind, we offer a 2-year warranty on all our evaporative coolers, which can be extended to 3 years when you sign up online.

ENERGY SAVING
Low power consumption, only a fraction of air condition. An evaporative cooler will only increase its cooling capacity when temperatures rise, without increasing the energy consumption.
FAQ's
Yes, evaporative coolers are highly effective, especially in hot and dry climates. They use the natural process of water evaporation to cool the air, providing a refreshing breeze with significantly lower energy consumption than traditional air conditioning. While they don’t lower temperatures as much as AC units, they efficiently cool large spaces, improve air circulation, and operate without refrigerants, making them an eco-friendly and cost-effective cooling solution.
The energy consumption of evaporative air coolers depends on the model. The Rex 14000 uses a maximum of 510 W/h, the Rex 25000 up to 850 W/h, and the Rex 48000 up to 1100 W/h, with a variation of ±10%. Their energy efficiency improves in hotter and drier conditions.
Water is supplied to the evaporative cooler either manually by filling the tank with a jug or automatically by connecting it to a continuous water supply. This ensures a steady flow of water to keep the cooling pads saturated for efficient evaporation and cooling.
Water consumption depends on conditions, but with a full tank, the cooler can typically run for an entire workday (around 8 hours). On average, the cooler uses 7.5L to 37L of water per hour, depending on the dry bulb temperature and relative humidity. For maximum cooling performance, using a continuous water supply is recommended, as it automatically maintains optimal water levels and ensures a steady flow of cool water for the best efficiency.
Rex Nordic air coolers slightly increase humidity as they use water evaporation to cool the air. However, they do not produce mist or excessive moisture, making them suitable for various environments without creating damp conditions. To maintain effective cooling and avoid excess humidity buildup, a constant flow of fresh air is needed.
Yes, Rex Nordic air coolers are ideal for dusty environments. The cooling pads not only cool the air but also act as filters, absorbing dust and improving air quality. This makes them a great choice for factories, warehouses, and other industrial spaces with high dust levels.
Yes, evaporative air coolers can be used in covered outdoor spaces. They provide a refreshing breeze without requiring enclosed areas like traditional air conditioning. However, they are not fully water-resistant and should be protected from direct rain. Their portability and ability to cool without refrigerants make them ideal for patios, covered outdoor events, warehouses, and other sheltered environments.
No, Rex Nordic air coolers do not have WiFi connectivity. They are designed for reliable, easy-to-use cooling without the need for complex digital controls, making them simple to operate in various environments.
In normal environments such as shopping malls, restaurants, and gyms, the cooling pads typically last 2 to 4 years. In dusty environments like CNC or metal factories, they may last 1 to 2 years due to increased particle buildup. The lifespan depends on the level of maintenance and care they receive.
