Watlow: Circulation heater
The CAST-X 3000 circulation heater, from Watlow, provides reliable indirect heating.
Typical applications include steam generation and superheating for process applications and applications where cleanliness is a major concern. Optional explosion-proof enclosure available. Heater consists of two helical coiled tubes and tubular elements cast into an aluminum body. The use of heavy wall 316L seamless process tubing provides reliability and high pressure operation. Heater features a fluid path independent of the heater sheath, an integrated thermostat housing, and dual tube construction allowing water flow rates to 20 GPM when run in parallel. Non-welded construction minimizes leakage, allows high-pressure operation and is self-draining when mounted vertically.
