Watlow’s CAST-X SERIES 1000 and SERIES 2000 circulation heaters are ideal heating solutions for demanding applications. CAST-X heaters consist of a helically coiled tube cast into an aluminum body with tubular elements. The aluminum body blankets the tubular elements and acts as the heat transfer media between the elements and the coiled tube through which the fluid being heated passes through.

This innovative and cost-effective cast construction provides multiple advantages compared to traditional circulation heaters. The unique construction of the CAST-X heaters allows the heater to be used where thermally sensitive materials are being heated such as paints, resins and flammable materials such as fuels and solvents. The CAST-X circulation heaters’ aluminum mass maintains heat accurately and consistently, resulting in an optimum level of temperature control. The aluminum body also efficiently conducts heat away from the tubular elements, prolonging heater life.
