Supported Applications
The Omega OMEGALUX® CS Series comprises Stainless Steel Sheath Cartridge Heaters designed to provide high wattage in limited spaces. These heaters are manufactured with precise dimensions and tolerances to ensure maximum heat transfer for minimum core temperature and faster heating. Documented applications include dies, molds, platens, heat sealing, labeling, packaging, and hot melt adhesive machinery.
Operating Conditions & Performance
The series is available in two construction types with distinct thermal limits:
- CSS Series: Features coiled resistance elements and ceramic cores for economical design. Sheath temperature rating to 677°C (1250°F).
- CSH Series: Features swaged construction for longer life at higher temperatures. Sheath temperature rating to 760°C (1400°F).
Heaters are designed to fit holes drilled and reamed to the nominal diameter of the heater. The series supports diameters from 3.2 to 19 mm (1/8 to 3/4") with lengths ranging from 25 mm (1 in) up to 305 mm (12 in). Standard voltage options are 120V and 240V.
Performance tolerances per the specification table include:
- Diameter Tolerance: From 0.025 to 0.229 mm (0.001 to 0.009") less the nominal diameter in inches.
- Length Tolerance: ±2% or ±1.6 mm (1/16"), whichever is greater.
- Camber Tolerance: 1.7 mm/m (0.020"/ft) of length for units up to 305 mm (12") L.
- Wattage Tolerance: +5% to -10% at rated voltage.
Note: Watt densities listed in selection tables are based on a unit installed in mild steel. Different materials affect these values; the lower the thermal conductivity of the material, the lower the maximum allowable watts per square inch.
Configuration Options
The CSS-CSH series offers configurable dimensions across diameter and length to match specific installation requirements. Key variant parameters include:
- Diameters: 3.18 mm (1/8"), 4 mm (5/32"), 4.76 mm (3/16"), 6.35 mm (1/4"), 9.53 mm (3/8"), 12.7 mm (1/2"), 15.9 mm (5/8"), and 19 mm (3/4").
- Sheath Material: 300 Series stainless steel.
- Lead Length: Standard lead length is 150 mm L (6"). Custom lengths are indicated in specific model numbers (e.g., "-24" LEADS", "-20"").
- Lead Insulation:
- CSH Series: Fiberglass, rated to 250°C (482°F).
- CSS Series: PFA for heater diameters of 6.4 mm (1/4") and smaller; Fiberglass for heater diameters of 7.9 mm (5/16") and larger.
The series supports a wide range of wattages depending on diameter, length, and voltage selection. Model numbers follow the format CSS-- or CSH--.
Key Product Differences
The primary distinction between series members is the construction method:
- CSS Series (Standard Construction): Utilizes coiled resistance elements and ceramic cores. This design offers an economical solution for standard heating applications.
- CSH Series (High Watt Density/Swaged Construction): Features swaged construction intended to provide longer life at higher temperatures compared to the CSS series.
Variations also exist in lead insulation materials based on heater diameter and series type. Additionally, specific model numbers include suffixes indicating non-standard lead lengths (e.g., 18", 20", or 24" leads) which differ from the standard 150 mm L (6") configuration.

while rated at 120V, but fail really quick at 120V
It'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.

Good product but slow shipping
It worked for me in a drilled aluminum block to cut pvc. Shipping was very slow (over two weeks). I think regular mail would been better but this option was not presented.

Great website and great products
Looking for a replacement heater for a small control box. Your website came up high on my Google search, easy to navigate website and numerous options came up that would fit our needs! Price was good and the delivery was fast.
Have used Omega products in the past and not been disappointed yet!

Can I operate the CSS-02120/120 cartridge heater in the dc voltage range from 0 to 120 Volt to adjust the power?
Thank you for your inquiry. No, this cartridge heater is designed to work only with AC volts.

Can these be submersed in water?
The CSH series heaters are not suitable for immersion into liquids. They are intended to be installed into machined metal blocks
so they can heat a larger mass so as to aid in proper heat dispersion. They are also not properly sealed for water submersion. You can look at the VPT series small immersion heaters, specifically the VPT-107/120V for a small cartridge style immersion heater.

Is it waterproof?? Can I put the wires all the way under water?
Thank you for your inquiry. Cartridge heaters are designed for dry environments only. The cartridge heater or lead wires cannot be exposed or submerged in water.

Can a DC voltage be used for the cartridge heaters?
The CSS and CSH series Cartridge Heaters can be used with DC Voltage.

I have a block of 6160 aluminum (8" x 5" x 2" thick) I want to use for a rubber curing platen. What probe would I use to get approximately 325 degrees? Or do you have a chart showing specific square inch of heating a particular thickness of material?
Hi rdjohn,
Thank you for the inquiry. You'll need to calculate how much heating power is required to heat up the block plus any mass that is in contact in a given period of time. With that info you can install 1 or 2 cartridges in to the block. Add a temperature sensor for feed back-control. Following link will provide some guidance;

CSS-03235/120V, What would be the heat up time to 300F? Considering for use in a continuous steam generator so maintaining temp under load is important. Need high steam output. PTC type heater is too slow recovery.
The sheath of the Cartridge Heater will heat very quickly but needs to be inserted into a tightly drilled out hole in a metal block. How quickly the block heats will depend on many things like the weight of the block, it's specific heat and the ambient environments temperature. Calculations can be found on line or you can email the Temperature Engineering group at temp@omega.com for advice.
