Watlow announces the introduction of the CAST-X 500 circulation heater. The newest and smallest heater in Watlow’s CAST-X product line is ideal for demanding gas and liquid applications and is intrinsically industrial safe. The heater is suited for applications where fluid cleanliness is critical because the gas or liquid being heated never comes in contact with the heater. This is a performance requirement in the semiconductor, analytical and foodservice equipment industries. The heater’s applications include the heating of solvent, DI water, air, CO2, nitrogen, diesel fuel and printing professional ink, as well as packaging sterilization, analytical instrumentation, steam generation and pasteurization in foodservice applications. The CAST-X 500 heater is constructed of a helical coiled tube cast into an aluminum body with a replaceable cartridge heating installed in the center. The aluminum body serves as the heat transfer media between the cartridge heater and the coiled tube where fluid is being heated. The unique construction of the heater allows it to be used where thermally sensitive materials are being heated, such as professional paints, resins and flammable materials. The aluminum mass acts as a “thermal flywheel” and ensures accurate temperature control of the fluid to prevent degradation. The heater’s compact size reduces space needs in customers’ equipment and assures quick response due to its low mass, making it a better overall thermal solution than oversized heat exchangers manufacturers.
