Precautions and conditions of use


Products > Cartridge heaters > Precautions and conditions of use

 

Do not use CCHC in the open air.
Do not handle them with cables.
Take care of the regulation and the position of the probes.
The assembly needs to be adopted according to the charge and the temperature between H11 and P7 (the most used is H7). But in the case of a high watts density, it will be sometimes necessary to reduce the hole fit.
Do not install too high wattages. In fact, heaters would be therefore more requested and would have a smaller life.
Always use as many heaters as possible to decrease the watts density (W/CM²).
The utilization of thermal grease favours heat transfer. Special greases (available on stock) avoid the oxydation of the boring and therefore the increase of the hole fit during the cartridge replacement.
Take care when using grease : it must not be in contact with cables or with the ceramic head.
Protect power cables from :
  • bendings
  • high temperatures
  • moisture
  • grease
  • materials absorption
  • thermal shocks.
The hole fit between the casing and the cartridge must be as small as possible to get a very good adjustment.
When using CCHC at high temperature or with an important thermal flow : it is necessary to use a regulation either external (temperature probe installed at about 15 mm from the CCHC) or internal (CCHC with an integrated thermocouple).
In case of surrounding moisture or if you don't use CCHC during several months : proceed by small successive heatings when you use it again.
