Immersion Cartridge Heaters for Liquid Applications:
For applications involving liquid immersion heating, we recommend utilizing brass or stainless steel threaded bushings.
The size of the threaded bushing is precisely matched to the pipe diameter. Available specifications include options like
G thread, NPT thread, and BSPP thread among others.
Step-by-Step Guide to Installing Cartridge Heaters:
1. Begin by crafting a precise and tailored hole in the area designated for heating, ensuring a seamless fit.
2. Ream a meticulously smooth hole to guarantee optimal contact and maximize heat transfer efficiency.
3. Extend the hole throughout the section, enabling effortless removal of the unit whenever necessary.
4. If creating a through hole proves impractical, enlarge the hole within acceptable tolerances to ensure proper fitment.
5. Reduce vibration and flexing of the lead wires to significantly enhance the service lifespan.
6. Protect the heater's end to prevent any liquid contamination, preserving its integrity.
When ordering Cartridge Heaters, kindly provide the following essential specifications :
1. Specify the Type of Cartridge Heater (refer to Termination Options for guidance).
