Air Conditioners

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.
