Delta Cabinet Heaters

Delta cabinet heaters provide reliable and efficient thermal protection for electronics and controls in low temperature environments. Delta heaters use a Positive Temperature Coefficient (PTC) heating element for increased safety and reduced operating costs. PTC heaters only generate the heat necessary for a desired temperature, versus at a constant rate, which saves energy while helping to prevent overheating and burnout. The heating element also cools down quickly. Fan and heater status are easily monitored via an LED status indicator. Operating temperature range is -40 to 65°C. UL, cUL, CE, TUV approved.
