Before installation, verify:
Voltage and power rating (e.g., 220V, 2kW)
Heater length and shape (e.g., L-shaped, over-the-side)
Chemical compatibility of the PTFE with your solution
Temperature rating (usually max. 260°C)
Before energizing the heater, fill the tank with the process liquid (do not operate dry).
Make sure the heater is fully submerged to the appropriate level (this is often marked on the heater).
The liquid should be compatible with PTFE (e.g. acids, alkalis, deionized water).
Over-the-side heaters are mounted to the wall of the tank using the L-bracket with the heater.
Do not allow the heater to touch any tank walls or the tank bottom to avoid damage.
Be sure to secure any cables or lead wires to avoid undue strain.
Connect the heater to a temperature controller or thermostat to prevent overheating.
Most systems use:
Thermocouples or RTDs for feedback
SSR (solid state relay) or contactor for switching
Do not connect directly to AC power without a controller.
Don't run heater dry (PTFE can overheat and fail)
Use liquid level protection (float switch or level switch) to remove power to heater when level drops
Ground and protect circuit (fuse or breaker)
Don't kink or pull on PTFE power cord
Set your target temperature on the controller (e.g., 60–80°C)
Monitor the process to ensure the heater is:
Not exposed to air
Not fouled with scale or sediment
Regularly inspect for any discoloration or damage to the PTFE surface
Periodically clean the heater using a compatible solution to remove buildup
Check terminals, power cord, and sensor condition
Replace the heater if PTFE shows signs of cracking or bubbling
