Our explosion proof multi split air conditioning systems allow you to control temperature in several locations, ATEX and non-ATEX, at once. A good economic, aesthetic and environmentally friendly solution in comparison with several single split systems. The temperature and capacity of the indoor units can be set individually.

Choose the most suitable indoor unit for every location to ensure optimum comfort, reduce the hazardous zone, safe energy and make the best use of the available space. Choose from a wall-mounted, a cassette or under-ceiling mounted indoor unit.

Suitable for a variety of industrial applications from various workspaces from small to large, which are classified as gas or dust explosion hazardous locations.

Our standard range of air conditioners are a modification of de latest models of Mitsubishi Electric. The outdoor unit, containing an explosion safe inverter heat pump, continuously adapts to the measured and desired temperature. This enables saving up to 30% on energy use and increases the comfort level for your workers.

On request, Ex-Machinery provides explosion proof conversions for other leading HVAC products and brands, such as Daikin, Carrier and Toshiba.

We gladly advise you for the best composition of your explosion safe multi split air conditioning system.
