Immersion Cartridge Heaters for Liquid Applications:
For optimal performance in liquid immersion heating applications, we recommend the use of brass or stainless steel threaded bushings.
The precise 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. Begin by crafting a precise hole in the section that requires heating, ensuring meticulous accuracy.
2. Ream the hole to achieve a smooth finish, optimizing contact for superior heat transfer and efficiency.
3. Extend the hole fully through the section, allowing effortless removal of the unit whenever necessary.
4. If creating a through hole is not practical, consider enlarging the hole size within acceptable tolerances.
5. Reduce vibration and flexing of the lead wires to significantly prolong the service life of the heater.
6. Guard against liquid contamination by effectively shielding the heater's end for reliable performance.
