Zone 1 & Zone 2 Hazardous Area Electric Heating

Hazardous Area Electric Heating

Hazardous area electric heating systems require reliable and accurate control systems to ensure precise and optimum process heating temperatures are maintained – this is especially applicable when controlling electric heaters with high power ratings where the thyristor switching effect can, if not correctly designed, cause interference with power supply and turbine operation.

Drawing on years of experience designing control systems for onshore and offshore installations – we understand the benefit of sharing this knowledge with our customers, engineering heaters that are designed to meet specific client specifications and complying to global quality standards for safe heating of explosive atmospheres and hazardous areas.
