Hazardous Area Fan HEATERS

ATEX Certified | Up to 40kW

Zone 1 & Zone 2 (IIB + H2) | T2 T3 & T4 Temperature Classes

EXHEAT LFH Fan Heater combines superior electrical heating efficiency with simple functionality to provide a next-generation heating solution for use in hazardous area environments where the explosive atmosphere is classified as Zone 1/2 (IIB+H2) according to the ATEX Directive.

Certified to the new EN 80079-36 and EN 80079-37 standards for constructional safety, the EXHEAT LFH is supplied ready to ‘plug and play’, with the option of fitting a plug, or hard wiring to an isolator unit.

Incorporating a stainless steel casing for added toughness and durability, the LFH electric fan heater manufactured by EXHEAT is designed to operate in ambient temperatures of -40°C to +40°C, and uses a framework allowing for multiple mounting options on floors, walls and even ceilings in explosive atmospheres.

Depending on the heater model selected, inlet air temperatures can be increased by up to 46°C. Heaters are available up to 40kW output and provide class leading, energy efficient heating solutions for both onshore and offshore applications.
