PTC hose heater

Increased flexibility:

Utilize connectors in several angles and dimensions and make PTC heaters even easier to install.

Efficient heating:

The heating element is placed in the middle of the aluminum housing and ensures that the coolant is heated quickly and efficiently.

Reduced power consumption:

The PTC element is self-regulating – no excess electricity is used.

No burn-off risk:

Because the PTC element is made of a self-regulating ceramic and contains no heating wire, there is no danger of burn-off.

Top-level security:

The new design removes the risk of coolant leaking into the heating element. It also prevents the pressure inside the housing from getting too high or too low.
