Watlow® Introduces CAST-X 3000 Circulation Heater For Reliable Indirect Heating

St. Louis - Watlow®, a designer and manufacturer of electric heaters, controllers and temperature sensors, introduces the CAST-X 3000 circulation heater - an economically priced heater offering high flow volume at the required temperature through a single compact product. Typical applications include steam generation and superheating for process applications and applications where cleanliness is a major concern. These include heating volatile materials in cases where contamination could be a problem such as deionized (DI) water and in food and beverage applications. The CAST-X 3000 is also available with optional explosion proof enclosure for use in hazardous environments.

This newest edition to Watlow's CAST-X family of heaters consists of two helical coiled tubes and tubular elements cast into a robust aluminum body which serves as the heat transfer media between the tubular element and the process tubes. The use of heavy wall 316L seamless process tubing assures high reliability and high pressure operation

The CAST-X 3000 features a fluid path independent of the heater sheath preventing fluid contamination, an integrated thermostat housing allowing the heater to run dry and the dual tube construction allowing water flow rates to 20 GPM when run in parallel. Its non-welded construction minimizes potential leakage, allows high-pressure operation and is self-draining when mounted vertically.
