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.

i need to heat a small metal bucket to 300 degrees fahrenheit and maintain it for about 2 hours. the metal bucket is grounded. can these heaters do that without shorting out?

Asked by: tattooboy13

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?

Asked by: steveH
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?

Asked by: Diana
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

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?

Asked by: Dovan
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.
