Safe Circulation Heater Ideal for Contamination-Free Gas and Liquid Heating

The new CAST-X 500 from Watlow® is a small, lightweight circulation heater ideal for heating gas or liquids in demanding applications. Even in its compact size, the CAST-X 500 is extremely powerful with operating temperatures up to 350°F (177°C) and working fluid pressure up to 3000psi. The CAST-X 500 heater is available in a variety of wattages and can be shipped in just a few days.

The CAST-X 500 heater is constructed of a helical coiled tube cast into an aluminum body with a replaceable cartridge heater installed in the center. The cartridge heater can be replaced with various wattages to suit your equipment’s changing requirements.

The aluminum body serves as the heat transfer media between the cartridge heater and the coiled tube where the fluid is being heated. The aluminum mass acts as a “thermal flywheel” and ensures accurate temperature control of the fluid to prevent degradation.

The unique, non-weld construction of the CAST-X 500 allows it to be used where thermally sensitive materials are being heated such as paints, resins and flammable materials.

The heater is suited for applications where fluid cleanliness is critical, because the material being heated never comes in contact with the heater. This is a performance requirement in foodservice, semiconductor and analytical industries.
