HVS' second generation Positive Temperature Coefficient (PTC2) heaters can improve the reliability, efficiency and operational life of electrical equipment by automatically maintaining an enclosure temperature only slightly higher than the outside ambient temperature without a thermostat or controls. The PTC2 performs this function better than the original PTC with a higher velocity fan while taking up less space and having no need for any special mounting platforms.

These economically-priced electrical cabinet heaters use a variable resistance (current limiting) material that automatically controls cabinet temperature. During cold weather when significant heat is required to reach the a thermostat setting, the PTC2 heater's integral circulating fan moves warm air around the cabinet, maintaining even heat distribution and providing uniform condensation protection as opposed to traditional strip heaters that oftentimes drive temperatures well above desirable levels in the areas around them.
