Immersion Cartridge Heaters for Liquid Applications:
For liquid immersion heating applications, we recommend using brass or stainless steel threaded bushings.
The size of the threaded bushing is matched according to the pipe diameter. Available specifications include
G thread, NPT thread, and BSPP thread, among others.
Step-by-Step Guide to Installing Cartridge Heaters:
1. Create a precise hole in the section to be heated for best performance.
2. Ream a smooth hole for optimal contact and significantly enhanced heat transfer.
3. Extend the hole through the section to facilitate the easy removal of the unit when necessary.
4. If making a through hole is not feasible, increase the hole size within the acceptable tolerances.
5. Minimize vibration and flexing of the lead wires to greatly extend the service life.
6. Prevent liquid contamination by carefully protecting the heater's end.
When ordering Cartridge Heaters, please provide the following details: :
