ECH(T) Compact heater with / without thermostat

This double insulated compact heater, ECH(T) is available with or without a thermostat. Water condensation is eliminated, also when the ambient temperature drops sharply. Choosing a version with an already integrated thermostat will save space inside the enclosure and reduce installation time compared with a thermostat mounted separately.

Double insulated compact heater, with or without a thermostat.


The housing of the heater is kept under 80°C due to the heaters double insulation. For the heater with an integrated thermostat, customers save installation time as the thermostat does not need to be connected.


When installed, water condensation will be avoided especially in situations when the ambient temperature dramatically drops. For the heater with an integrated thermostat, customer's labour costs are reduced due to not having to install a separate thermostat, which also saves space inside the enclosure.


A thermostat with a normally closed contact, ETR or EFR, is recommended in order to control the heater.
