Compact Enclosure Heaters

ATEX Certified

EXHEAT FXS compact enclosure heaters provide flameproof, hazardous area heating and air warming for Zone 1 & Zone 2 (Flammable Gas) and Zone 21 & Zone 22 (Dust) explosive atmospheres according to ATEX Directive.

The FXS range of self-regulating enclosure heaters provide a bespoke solution tailored to suit your requirements operating safely without a thermostat thanks to the heaters inbuilt ability to reduce the output as the temperature increases.

FXS enclosure heaters can operate in ambient temperatures as high as 130°C (T4) or 180°C (T3) and down to -60°C.

The FXS concept can be applied to practically any enclosure or component heating requirement. Designs utilise an anodised aluminium body fitted with a self-regulating PTC cartridge type heating element in order to provide effective heating of enclosures via convection and radiation.

Features of EXHEAT FXS Compact Enclosure Heaters

  • Hazardous Area Certification –  ATEX, IECEx and CU TR (EAC) standards
  • Design – hard anodised aluminium housing for onshore and offshore applications
  • Installation – can be directly mounted to the component that requires heating
  • Enclosure heaters that are compact and efficient
  • T Classes – heaters available in T3 and T4 temperature classes
  • Temperature Range – FXS compact enclosure heaters suitable for ambient temperatures as low as -60°C and up to +180°C
