PH (Professional Heater)

 
    The new model with designation PH (Professional Heater), has some product improvements such as the size, which simplify the installation. The new PH is also equipped with a rubber sealing for increased service life and reliability.
The new PH heater is equipped with overheating protection and a thermostat. The PH is delivered as before as a complete kit with heater, cables, bracket, etc. or as only the heater with bracket.
 
     
    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 (20mm). As with the insertion heater, the PH is based on the self-circulatin principle.
PH engineheaters are equipped with an overheating guard and a thermostat.

The PH500L - 2000L engine heaters are specially designed for stationary engines that must be warm and ready to start
for long periods. Thermostat regulated with switch-off at 50º C (+/-5 ºC) and switch-on at 25º C (+/-5 ºC).

Engine Block Heaters
 



1. Retainer plate

The existing frost plug hole is used.
The engine heater is held in place by a retainer plate bolted to the engine block. Sealed with an o-ring or profiled gasket.


 
       
       
 



2. Threads

The heater can be installed in a threaded hole if one is available. Sealed with an o-ring or profiled gasket.


 
       
       
 


3. Tapered

If access is restricted, e.g. narrow coolant channel, a tapered engine heater can be used, installed in the frost plug. Drive into the hole and then wedge firmly. Seal against the block using a taper, which can be supplemented by sealing agent appropriate for the environment.


 
       
       
 



4. Hose heater

The heater is installed in the lower radiator hose. This is not a universal solution and should only be used after thorough testing and according to Calix' recommendations.


 
       
       
 



5.Cross piece

Also installed in the frost plug hole. The heater is held in place with a cross piece functioning as an anchor. Sealed with an o-ring or profiled gasket.


 
       
       
 



6. Others

The heater is shaped and installed against the block wall here. Generally used when the engine block is aluminium.
