200w Flexible Silicone Rubber Drum Heater With Temperature Sensor For Fermenter Tank

Flexible silicone rubber heaters use wire-wound elements (resistance wire) laminated between silicone rubber to ensure a uniform heat profile and excellent physical strength. This technology is typically used in lower volume or larger size applications as it is easier to conform to the size and shape of the application, avoiding holes and cutouts, or to concentrate the heat profile in a specific section or sections of the heater as required. Wire wound design is a solution to the limitations or etched foil technology.

* The silicone rubber heaters have advantage of thinness, lightness and flexibility;
* It can improve heat transfer, accelerate warming and decrease power under the process of operation. Fiberglass reinforced silicone rubber stabilizes the dimension of heaters;
* The max wattage can be made for 1 w/cm²;

* The heaters can be made for any size and any shapes.

• Nickel Chrome (NiCr) alloys are the most common material used in silicone rubber heater applications with maximum operating temperatures up to 1,250°C (2,280°F). Typically called Nichrome wire, it is a non-magnetic alloy that has high resistivity and good oxidation resistance.
• Copper Nickel (CuNi) alloys have medium range electrical resistivity and very low temperature-coefficient of resistance so they are typically used in flexible heater applications with maximum operating temperatures up to 600°C (1,110°F).
• Iron Chrome Aluminum (FeCrAl) alloys are high-resistance materials with very good form stability resulting in long element life typically used in applications with maximum operating temperatures up to 1,400°C (2,550°F). Because silicone rubber heaters made with this material will have higher surface loading capability, higher resistivity, and lower density than traditional Nichrome alloys, the heater can be designed with less material to provide weight savings.
