Flexotherm™ is proud to produce heated drum heaters and insulating blankets. Flexotherm™ drum heaters and insulating blankets are made of silicone rubber-reinforced fiberglass cloth laminated around a nickel alloy circuit. This build affirms that the heaters provide an even and consistent heat transfer throughout the product. The drum heaters are outfitted with a spring and hook system to easily fit around 5, 15, 30, or 55 gallon drums. This design ensures that the drum heater will be readily available for whatever size the application calls for. We also offer custom configurations for those that need more precise specifications for their application or job.
