Ceramic fiber Heaters

Electric Heaters

Circulation and Process Heaters Ceramic fiber heaters integrate a high temperature iron-chrome-aluminum(ICA) heating element wire with ceramic fiber insulation. Numerous stock,standard and/or custom shapes can be provided, achieving the “heated insulation” concept for your high temperature, non-contact applications. The ceramic fiber insulation isolates the high temperatures inside the heatedchamber from the outside. The heaters are low mass, fast heating, with high insulation values and the self-supported industrial heating elements that offer some ofthe highest temperature heating capabilities within the Watlow family of heaterdesigns.The sheath material available is molded ceramic fiber.

Product Overview

Watlow’s circulation heaters are compact heating solutions for fluids such aspurified and inert gases, supercritical fluids and liquids like de-ionized water for use in semiconductor and electronics industries as well as for general liquid and gas heating applications. Watlow’s industrial process heater lines ofimmersion, circulation and duct heaters are used to heat a myriad of high and low viscosity fluids ranging from de-ionized and process water, oils, solvents,rinse agents, caustic solutions, etc. to process gases like air, nitrogen, purifiedand inert gases as well.
