explosion proof heaters


Categories: ,


1 Application

Direct-heaters for Hazardous locations, designed for direct mounting onto e.g. manifolds etc.

  • Freeze protection
  • Anti-condensation
  • Temperature maintenance

2 Features and Advantages

  • Self-limiting heating elements
  • Small dimensions
  • No moving parts, no maintenance required, therefore long lifetime
  • Suitable for T4 and T3 classifications
  • Can be used for 110/240 VAC/DC

3 Remarks

  • All Cameo Heaters are designed around self-limiting heating elements. These semi-conductor elements are saving power consumption. Our Cameo Direct-heaters are designed to heat the installed equipment. If properly selected for freeze protection, no thermostat will be needed.
  • When required in other applications, e.g. analyzers, it is normal practice to use our Direct-heaters
    in combination with our Fix-Therm96 thermostats (range from 10°C up to 135°C) or our FixTherm Inline Thermostat(range from 10°C up to 60°C).
