Immersion Cartridge Heaters for Liquid Applications:
For superior performance in liquid immersion heating applications, we recommend the use of brass or stainless steel threaded bushings.
The threaded bushing size is precisely matched to the pipe diameter. Available specifications include
G thread, NPT thread, and BSPP thread , amongst others, to suit diverse application needs.
Comprehensive Manual for Effortless Installation of Cartridge Heaters:
1. Meticulously craft a precise opening in the target section to ensure optimal heating.
2. Skillfully ream a smooth hole to guarantee superior contact and maximize heat transfer.
3. Strategically extend the hole throughout the section, simplifying the unit's removal as needed.
4. Should a through hole not be viable, ensure to enlarge the hole within permissible tolerances.
5. Diminish lead wire vibration and flexing to significantly enhance service life durability.
6. Ensure the heater's end is safeguarded to prevent any liquid contamination.
To ensure precise ordering of Cartridge Heaters, kindly provide the following information :
1. Designate the Cartridge Heater type (refer to Termination Options for guidance).
