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.

Advantages of Self-Regulating Cartridge Heaters

Hermetically Sealed
Cartridge heaters are designed to operate fully submerged in a liquid as well as air. This also protects the heating element from corrosion, ensuring long-term reliability.
No Additional Control Required
With their self-regulating operation, these cartridge heaters reduce power consumption without the need for any external temperature control
Built to Your Specification
Heaters can be desinged for any temperature up to 200°C and including your choice of wattage, power supply, length, shape and choice of terminals
Robust Construction
Each heater is produced using a stainless steel sheath, PTC ceramic component with MgO insulation and a 'cold area' silicone electrical cable. Heaters are tested to EN60335 and EN50106 standards.
