Enclosure Heaters

Enclosure heating is sometimes required to keep internal temperatures within the operating range of electrical components, especially when an enclosure is installed outside in an area where ambient temperatures dip well below freezing. More importantly, heating is needed to reduce moisture and related corrosion. The goal of enclosure heating is to keep the relative humidity inside below 65%. A consistent temperature helps guarantee optimal operating conditions and prevent condensation. Optimal performance is achieved by placing the heater near the bottom of the enclosure to allow natural convection for heat distribution. Larger enclosures often require fan heaters to distribute the heat throughout the enclosure.

Hoffman Heaters protect mechanical and electrical equipment from low temperatures, condensation and corrosion. The heaters maintain stable enclosure temperatures by using natural convection resulting in current circulation of warm air. Hoffman Electric Heaters are fan-driven, thermostatically controlled heaters that maintain a stable enclosure temperature. The fan draws cool air from the bottom of the enclosure and passes the air across the thermostat and heating element before releasing it into the enclosure cavity. Heated air is discharged through the top of the heater unit.

Pfannenberg Heaters with Thermostats are designed to protect electrical components from low temperatures, condensation and corrosion. The built in thermostat allows the heater to be set to the precise temperature required for the application. Pfannenberg Mini Radiant Heaters are ideal for small outdoor enclosures and Pfannenberg FLH Heaters are ideal for larger electrical enclosures.
