CAST-X 2000

CAST-X 2000
The CAST-X 2000 circulation heater from CAS is an ideal heating solution for demanding applications. The CAST-X 2000 heater consists of a helical coiled tube cast into an aluminum body with tubular elements. The aluminum body serves as the heat transfer media between the tubular element and the coiled tube through which the fluid being heated passes through. The unique construction of the heater allows it to be used where thermally sensitive materials are being heated such as paints, resins and flammable materials such as fuels and solvents. The aluminum mass acts as a “thermal flywheel” and ensures accurate temperature control of the fluid to prevent degradation. The CAST-X 2000 is available with optional explosion proof enclosure for use in flammable environments.

The CAST-X 2000 is well suited to applications where fluid cleanliness is critical because the material being heated never comes in contact with the heating elements. This is a performance requirement in the food service equipment, semiconductor and analytical markets. The CAST-X 2000 heater comes with a heavy wall seamless stainless steel passageway that assures performance in high-pressure applications where viscous or mildly corrosive materials need to be heated
