Anti Condensation Heaters
Natural Convection Anti-Condensation Heaters For Enclosures and Control Panels
Comprehensive ranges of anti-condensation heaters for a wide range
of applications and enclosure sizes
- HG- PTC resistor, self regulating and temperature limiting
- MHT- PTC protected mini heaters with 400mm long wires from 5-30W
- SHT- PTC protected with terminals from 25-150W
- SHT/W- PTC protected with 400mm long wires from 15-50W
- Fast and simple installation With mounting for 35mm DIN EN 50022 rail.
Three ranges of anti-condensation heaters ranging from 5W to 150W all with natural heat convection.
The HG series are self regulating and are fitted with pressure clamp terminations.
The MHT,SHT and SHT/W ranges are Class II and have voltages including 110-250V AC or DC
Thermostat / HygroStat
KTO & KTS Heating and Cooling Thermostats
ZR Double Thermostats and MFR Hygrostats
Comprehensive ranges of heating and cooling thermostats, double
thermostats and thermo-hygrostats.
- KTO 011 thermostats with normally open contacts for cooling devices
- KTS 011 thermostats with normally closed contacts for heating devices
- ZR 011 double thermostats with dual contacts for heating and cooling devices
- MFR 012 electromechanical hygrostats for control of enclosure heaters with high humidity or low temperature triggering
- All with mounting for 35mm DIN EN 50022 rail.
Three ranges of control devices for the accurate control of heat , condensation and humidity.
The KTO 011 and KTS 011 thermostats operate with a snap action, bimetallic, two pole contact set .
The ZR 011 double thermostat offers dual control in a single unit, maximising space and simplifying wiring . Normally closed contacts are used for regulating heaters and normally open contacts are used for egulating cooling fans, heat exchangers or switching signalling devices. Heaters and cooling equipment can be switched independently with a temperature offset rather than the usual change-over contacts.
The MFR 012 electromechanical hygrostat triggers for high humidity or low temperature and has changeover contacts. Designed to control heaters when a critical relative humidity of 65% is reached.
All units are designed of mounting on a 35mm DIN rail.
Three ranges of anti-condensation heaters ranging from 5W to 150W all with natural heat convection.
The HG series are self regulating and are fitted with pressure clamp terminations.
The MHT,SHT and SHT/W ranges are Class II and have voltages including 110-250V AC or DC
