SunRod Miniature Cartridge Heater

Self-Regulating PTC Cartridge Heaters - Designed for Drip Trays

A robust cartridge heater suitable for maintaining a low temperature in a rapid and controlled way. Once the desired set temperature is reached, and its maximum power is met, the heater responds by cutting the power automatically. No external control or monitoring method is required.

Hermetically sealed, these cartridge heaters can be immersed in water, making them suitable in either plastic or metal drip trays. 

Available in lengths between 100mm and 700mm, the cartridge heaters can be produced in straight or curved body designs. 
Commonly installed in refrigeration drip trays for the evaporation of condensate, self-regulating cartridge heaters can also be used in a other applications where low level heat is required, such as crankcase heaters, vending machines and coffee makers.
