CR 027 PTC Fan Heater 400 - 650W
Compact fan heater
Heating power adjusts to ambient temperature
Integrated adjustable thermostat
Built-in overheat protection
DIN rail mountable
The semiconductor CR 027 fan heater prevents the formation of condensation and ensures an
even temperature in enclosures. The integrated thermostat is used to set the desired tempera-
ture while the high performance axial fan provides forced air circulation. The CR 027 is also
available with a continuously running fan (when powered).
