HRH ATEX Immersions

When environmental conditions become unsafe to use ordinary immersion heaters, Heatrod can offer a wide range of explosion-proof heating solutions.

Having manufactured our first range of hazardous area heaters back in 1953, Heatrod can provide a hazardous area version for the majority of our products, together with bespoke hazardous area air and gas heaters. Fully ATEX certified to class IIB and with standard screw-in immersions up to fully engineered 180kW process heaters. We can also provide IIC certified products from other group manufacturers.

The term 'explosive atmosphere' is defined as a mix of inflammable substances in the form of gases, vapour, mist or dust - which may lead to fire spreading to the un-burnt mix following ignition. Atmospheric conditions are normally defined as -20°C to +40°C, pressure 0.8-1.1 bar. We produce equipment for ATEX areas, with different temperature and pressure on the media and for all temperature classes.
