Explosion-proof heaters
ATEX – Standard
Explosion-proof heaters are used in many industrial or commercial applications that are classified as hazardous areas. Our appliances are used to heat the ambient air of hazardous areas in zone 1 and 2, typically in chemical industries, paint and lacquer industries, sewage plants and mining. Heaters made of high-grade stainless steel are recommended for aggressive environments (e.g. sewage plants), while heaters with a painted or coated surface, also available with protection basket, are sufficient for standard applications.
Available on request: further types of explosion-proof heaters and our technical data sheets, as well as the TR-CU certificate.
Temperature classification: T4 < 135°C, T3 < 200°C, T2 < 300°C
