- For closest fit and best heat transfer, use reamed holes.
- When possible, drill holes through the object being heated. This will make heater
removal easier.
- When using an anti-seize coating like Tempco’s BNS
spray or paste, do not apply over lead wires or any other current carrying conductors.
- When using insulated tape or sleeving, check to make sure they are rated for the
temperature of the application. Lower temperature rated materials can contain an adhesive
or binder that can carbonize and become electrically conductive.
- When using heaters near their maximum recommended watt density, it is recommended the
temperature sensing probes be approximately 1/2" from the heater sheath.
- Lead wires should not be located in the hole containing the cartridge heater during
operation. This may cause the lead wires to be exposed to temperatures above their rated
temperature.
- When used in a vacuum application, make sure the lead end of the heater is outside the
vacuum. If the lead has to be in the vacuum, consult Tempco for specific recommendations.
- Many applications will subject a heater’s electrical terminations to one or more of
the following potentially damaging conditions:
• Moisture
• Flexing
• Oil and other contaminants
• Abrasion
• High temperature
Note: To protect the heater from damage in these harsh environments, Tempco has a wide
selection of terminations and options available. |
