Explosion-proof OVEx heaters

Explosion-proof OVEx heaters are used for heating industrial premises, warehouses for paints and varnishes and other flammable materials, mobile buildings and containers with technological equipment. Explosion-proof heaters can be used both as an independent and as an additional or backup source of heating.

The explosion protection marking 1Ex d IIB T4 Gb X assigned to heaters in accordance with GOST IEC 60079-1-2011 allows them to be used in explosive zones of class 1 and 2. Compliance with TR TS 012/2011 “On the safety of equipment for operation in explosive environments” is confirmed by a certificate.

Construction

The explosion-proof air heater consists of a steel casing, inside of which a bimetallic heat exchanger is installed. Propylene glycol is used as a heat carrier, heated by an HBEx flange heater. The thermostat installed inside the HBEx heater maintains the coolant temperature in automatic mode. The housing is equipped with aluminum blades at the heater outlet. Also inside the case there is a spark-proof fan impeller, it is driven by an explosion-proof electric motor. The engine is mounted outside the housing on a special bracket. An explosion-proof terminal box is fixed on the side panel of the heater, inside it there are power supply terminals and ballasts.

Convention structure


The symbol does not provide an opportunity to obtain comprehensive information about the characteristics of the heater, descriptive information is contained in the agreed design documentation and specification.
