Cast Aluminum Solutions Cast-X 500 Circulation Heater

  • Long-Lifespan, Low-Maintenance Design
  • SS 316L Fluid path separation for safety
  • Self-Draining, reduce material entrapment
  • UL -Approved Heating Elements


The Cast-X 500 Circulation Heater is a low-watt-density heating element designed and manufactured by Cast Aluminum Solutions (CAS). Cast-X Circulation Heaters are engineered using the latest thermal modeling and finest element analysis technology. Additionally these heaters contain helical-coiled stainless steel flow path tubes which have critical safety benefits. The media is sequestered in tubes, never touching the heating element. These heaters are especially safe in explosive or sensitive heating applications.

In addition, Cast-X Heater series are self-draining for safety and cleanliness. With compact, non-welded bodies, plus NEMA and ATEX enclosure, Cast-X units are small-footprint, high output heaters that meet the needs of high-purity processes, flammable operations, and your most critical heating applications.

Cast-X circulation heaters have multiple sensor options including type K or J thermocouples. These heaters also have sensor options with snap-action high-limit thermostats for temperature control.  Other accessories include insulating jackets and compression fittings.
