1 Application

Space-heaters for Hazardous locations are designed for

  • 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 Space-heaters are designed around self-limiting heating elements. These semi-conductor elements are saving power consumption.
    Our Cameo Space-heaters are designed to heat the air inside an enclosure and indirectly 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 Space-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).
  • Do not cover the fins to guarantee free convenction.
