Self-regulating heater

A PTC heating element is a ceramic-based electrical component that self-regulates its temperature and cannot overheat, ensuring safety and reliability.

Energy efficient

The power output of a PTC duct heater varies with heat extraction. The heater automatically adjusts temperature and increases power when excessive heat is extracted, but decreases power and restricts current flow at maximum temperature.

Simple control

The PTC heater can be controlled linearly with an analogue signal (0-10V) or with Pulse-width modulation (PWM) signal. All connection terminals are easy to access.

Easy to install

Horizontal or vertical installation in the supply or outdoor air ducts (DN125).

High operational reliability and energy efficiency without any additional switching elements.
