ATEX Fan Heaters – Hazardous Area Zone 1 & Zone 2 – EXHEAT LFH


Zone 1 & Zone 2 (IIB + H2) 

EN 80079-36 and EN 80079-37 Compliant

EXHEAT is proud to present to the market the LFH Fixed Fan Heater incorporates unrivaled efficiency with ease of use offering a heating solution for hazardous areas (ATEX, IECEX and CU TR EAC) where the atmosphere is classified as Zone 1/2 (IIB+H2).

The LFH Fan Heater comes ready to ‘plug and play’, with the option of fitting a plug, or hard wiring to an isolator unit.

Integrating a stainless steel robust casing for added toughness and durability, the LFH has been developed to function in ambient temperatures of -40°C to +40°C, and uses a framework allowing for multiple mounting options on floors, walls, and even ceilings.
