OMEGALUX™ CS series cartridge heaters provide high wattage in limited spaces. They are manufactured with 300 series stainless steel sheaths to precise dimensions and tolerances to ensure maximum heat transfer for minimum core temperature and faster heating. The CSS series cartridge heaters utilize an economical design of coiled resistance elements and ceramic cores, and can be used whenever a high Watt density is not required. The CSH series are high Watt density cartridge heaters which feature a swaged construction which allows for longer life at higher temperatures. See graph (below) for the maximum recommended Watt density when selecting the high Watt density, CSH series, cartridge heaters.
CSS and CSH series cartridge heaters are designed to fit into holes drilled and reamed to the nominal diameter of the heater. The hole should be reamed to the fractional size with a +.001" tolerance.

Rated 4 out of

Mike Tan from
while rated at 120V, but fail really quick at 120VIt's a great C heater, but can't really used at 120V. We tried at 85V, still ok, didnt dare to go any higher.
I called omega engineer once to discuss this issue. They quickly referred to the lead wire issue. I then have replaced the entire lead wire cloth with ceramic beads, the voltage issue still remains. Also, there is like 4 mm cloth within the heater which is hard to be removed. I understand there is more expensive ones for vacuum application, but some customers just have limited funding.
Overall, it's great heater, but with some issue that we need to be aware of.
