Hazardous Area ‘L’ Immersion Heaters

The ISES-L series of hazardous area immersion heaters are ideally suited for installation within process tanks, sited in ATEX / IECEx Zone 1 or Zone 2 hazardous areas. The design of the heater provides horizontal mounting of the elements, beneficial for low liquid level applications but allowing vertical installation, which facilitates withdrawal from the vessel top.

The design of the heater is particularly suited for heating the contents of underground storage tanks.
