Touch-Safe PTC Heater CSK 060

10 & 20 W

The CSK 060 is a touch-safe PTC heater for use in enclosures. The design of the heater utilizes natural convection which results in a circulating current of warm air. The surface temperatures on the accessible side surfaces of the housing are minimized as a result of the heater design.

Moisture can build up not only in outdoor or poorly insulated enclosures, but also in highly protected and well-sealed enclosures. ISC’s wide variety of heaters prevent moisture from harming sensitive equipment.
