Exd Electric Immersion Heater

Type SIH KLXT n,n H/M/L-nnnExd

GENERAL INFORMATION.

This product is an electric immersion heater intended for use within a potentially hazardous areas where a risk for exposure to explosive gas atmosphere exist.
The heater must be horizontally mounted into a tank, vessel or a pipe-based flow through system, and the heating elements shall be totally immersed in liquid during operational use.
The heating elements submerged in liquid, is considered as a non-Ex area.


TYPE DESIGNATION AND DESIGN

The immersion heater’s type designation is SIH KLXT…H/M/L-…Exd.
Its main parts are the electric heating elements brazed into a BSP G2” threaded bulb-head manufactured in stainless steel AISI316L, and Exd junction box made of cast aluminum.


CONTROL AND LIMITATION OF TEMPERATURE

The heater is controlled by automatically resettable thermostat that regulates the temperature and determines the T-class. Set-point must be agreed with manufacturer when placing order, and cannot be adjusted by end-user.


An additional manual resettable thermostat is mounted for the safety (TSHH). T-class for this equipment is based on the TSHH cut-off.


TSHH is preset and fixed at its set-point.
