PTC Heaters

The Heat Source ONE heater (HS1) can improve the reliability, efficiency and operational life of electrical equipment by maintaining an enclosure temperature only slightly higher than the outside ambient temperature. Its integrated fan assembly ensures even heat distribution throughout the enclosure while minimizing the impact of dusty environments.

Features

• IP55-rated fan bearings able to withstand harsh environments
• Temperature cutoff after reaching 40⁰ C (104⁰ F)
• Energy efficient
• Low electrical noise
• Low surface temperature – “Safe Touch”

Operation

Our HS1 heaters are constructed with a variable resistance (current limiting) material that automatically controls the cabinet temperature to reduce heater output as the input temperature rises. PTC heating “stones” moderate the heater output and ensure an even distribution of warm air throughout the cabinet, increasing heater reliability and efficiency.

Our second generation positive temperature coefficient 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 using a thermostat or controls, thereby protecting against heat damage and condensation. The second generation version performs this function better than the original heater 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 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.
