Immersion Cartridge Heaters for Liquid Applications:
For effective liquid immersion heating, we suggest using brass or stainless steel threaded bushings.
Threaded bushing size is precisely matched 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 that requires heating for optimal performance.
2. Ream the hole smoothly to ensure the finest contact and superior heat transfer efficiency.
3. Extend the hole through the section, facilitating effortless unit removal whenever necessary.
4. If forming a through hole is impractical, enlarge the hole within permissible tolerances.
5. Reduce vibration and flexing of lead wires to significantly prolong service life.
6. Protect the heater's end to prevent liquid contamination and ensure durability.
When ordering Cartridge Heaters, kindly provide the following details for precision: :
