FP-MLH & FP-MLHX EXHEAT Hazardous Area Flameproof Mini Line Heaters - ATEX Zone 1 & Zone 2

EXHEAT FP-MLH & FP-MLHX Hazardous Area Flameproof Mini Line Heaters - ATEX Zone 1 & Zone 2

ATEX Certified Zone 1 & Zone 2 Flameproof Mini Line Heaters for Flowing Liquid, Air or Gas

EXHEAT provides a range of flameproof mini line heaters that provide efficient heat transfer to flowing liquids, air or gases with hazardous areas where the flammable atmosphere is a IIC gas group. The mini line heaters are fitted with either a screw plug or flanged immersion heater mounted within a mineral wool thermally insulated mild steel or stainless steel heating vessel.

FP-MLH hazardous area mini line heaters are ideal for water applications with a incoloy rod type heating element and are available for a range of power outputs with either a 475mm short body or a 925mm long body. FP-MLHX hazardous area line heaters are more suited for oil heating applications due to the heating element being made of a withdrawable ceramic core and are only available in the 925mm long body model. 

Both the FP-MLH and FP-MLHX hazardous area mini line heaters have a lightweight cast aluminium terminal enclosure which is certified weatherproof to IP67 and are suitable for ambient temperatures from -40ºC to 40ºC. A range of built in temperature sensors and externally adjustable thermostats are available.

Typical applications in water heating of wash rooms and hot water storage tanks, frost protection of pre start systems for water cooled engines and fire extinguishing equipment, fuel oil heating and heat transfer oils.
