Air Unit Heaters

Air unit heaters for use in potentially explosive atmospheres have explosive protection complying with Directive 94/9/EC (ATEX) and therefore conform the requirements of BDS EN 60079-0. Axial fans which are elements of the units are coupled with electric motors intended for use in potentially explosive atmospheres with different protection type (ExII2GExeII, ExII2GExd(de)IIB(C), ExII2DExtDA21IP65T125°C, etc.) and temperature class of T1 to T5. They have been specifically designed for use in hazardous zones for gas/vapour and aerosols: zone 1 and zone 2 and zones for combustible dust: zone 21 and zone 22, in agreement with BDS EN 1127-1. Air unit heaters for use in a potentially explosive atmosphere are designed to heat and ventilate stores, garages, work storeroom and other places where potentially explosive atmosphere can exist.
