Calix Blockheater PH 500L

Insertion heaters cannot be used for certain vehicles, such as certain construction machinery, tractors, lorries and, in exceptional cases, some passenger cars.

The solution in these cases is a Calix PH. This heater is connected to the cooling system outside the engine block using a hose connection (20 mm). As with the insertion heater, the PH is based on the self-circulation principle and fulfils all requirements that can be set for a heating system. Calix thoroughly-tested PH engine heaters are equipped with an overheating guard and a thermostat.
