Frequently asked questions
How do I choose the right watt density?
The hotter the process and the looser the fit in the hole, the lower the watt density should be. Share your operating temperature and hole size and we will recommend a safe rating. Our guide How to choose the right cartridge heater explains this in detail.
Why do cartridge heaters fail early?
The most common causes are a loose fit in the hole, too high a watt density, moisture or oil entering the lead end, and lead wires flexing in moving tools. Read 7 common causes of cartridge heater failure or tell us how your old heater failed.
Can you match my existing heater?
Yes. Send a photo or drawing with diameter, length, wattage and voltage, or send the old heater, and we will manufacture an equivalent.
