CAST-X 4000

 
CAST-X 4000
The new CAST-X 4000 circulation heater from CAS delivers high flow volume and electrical power in a compact unit. The CAST-X 4000 is available in single or double tube versions for maximum flexibility and efficiency. The media being heated never comes into direct contact with the heating elements reducing the risk of fluid contamination.

The compact size of the heater is made possible by our cast-in construction. By design, the heater elements are completely embedded in the aluminum. This heats the aluminum mass, creating a thermal flywheel which efficiently transfers heat to the heavy wall 316L stainless steel tubing which is also cast-in. The resulting product delivers maximum power and capacity in a small footprint.

Since the material being heated in the tubing never comes into direct contact with the heating elements, the CAST-X 4000 is ideal for indirect heating applications where contamination and fluid cleanliness are important.

The CAS design outlasts, and out performs a typical immersion heater. The Cast-X 4000 delivers superior performance and long life. With very low maintenance, downtime is minimal and overall cost of ownership is low.
