CAST-X 1000

CAST-X 1000
The CAST-X 1000 circulation heater from CAS consists 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 circulating the heated fluid. This innovative and cost-effective cast construction provides multiple advantages compared to traditional circulation heaters. The CAST-X 1000 circulation heater’s 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.

The reliable construction of CAS’s CAST-X 1000 circulation heaters allows fluid to circulate through a coiled tube instead of in direct contact with tubular elements. This feature eliminates hot spots caused by poor flow conditions that typically result from contact between tubular elements and the heated fluid. In addition, because the unit can run dry with the thermostat without damage, there is less chance of overall heater failure and fluid leakage.

The robust, rugged design of CAS’s CAST-X 1000 circulation heaters also delivers problem-free operation in a more compact size than traditional heat exchangers. The CAST-X 1000 circulation heater is appropriate for numerous applications and may be customized to meet specific customer needs.
