Heater Material
Silicone rubber fiberglass insulated flexible heaters can improve heat transfer and speed warm-ups where controlled heating is required in confined areas. Two circuit designs are available: etched foil or wire wound. Heaters with etched foil designed elements are available where the length or width dimension is less than 10"(254 mm). All other heaters where both the length and the width dimensions exceed 10" (254 mm) use the wire-wound element design. Effect of power density: gentle warming is best done with 2.5 W/in2. An excellent all-purpose unit is the 5 W/in2. Rapid warm-up and high temperature are achieved with the 10 W/in2; however, the temperature must be controlled as the safe maximum operating temperature limit of 450°F (232°C) may be exceeded.
CAUTION AND WARNING!
Fire and electrical shock may result if products are misused or installed or used by non-qualified personnel. See inside back cover for additional warning.
Applications

Easy to install and functional.
We are using them to bake an ultra-high vacuum chamber and they work very well.

Buyer be where
Picture is not what you will get. Nothing stated item will need other parts to work. Returned item at additional cost. VERY Frustrated.

we are using these flexible rubber heaters with the CN16D3-R-AC PID controller and we are experience relay failures on the PID controllers. What do you recommend for protection of the mechanical relays when switching on these rubber heaters?
Thank you for your inquiry. For PID Control, which has continuous relay cycling, use a CN16D3-S-AC controller with a SSRL240DC10 Solid State Relay.

I need a pad that heats to 98 F and maintains at +- 2 degrees. Do any of these products do this? A 10 inch to 6 inch square works well. Thanks
Thank you for your inquiry biggbell. Unfortunately, we need more information in order to recommend a product like the power and power density. Please send an email to heaters@omega.com that way one of our engineers can provide further assistance.

i want to use a heater to heat and maintain a chamber at 140 degrees for extended periods of time. will something like a 10X11 silicon mat work to heat quickly?
This would heat the material that it is attached to quickly if you purchase in 10 watts/sq. inch, but for chamber heater quickly, we would suggest some type of enclosure heater which would be more efficient. If you search our site by this keyword you will find various ones that can be chosen.

Hi! I want to use this to sit on the stage of an extrusion printer I am experimenting with. Does this come with a temperature controler or would I need to buy that separately?
Thank you for your inquiry Diana. These heaters don't come with a temperature controller. You would need to buy them separately. Here is the general link to our PID controllers: https://www.omega.com/en-us/control-monitoring/controllers/c/pid-controllers
