Watlow's new CAST-X 2000 circulation heater is an ideal heating solution for a variety of applications, especially where fluid cleanliness, temperature accuracy and high pressure are needed. These versatile heating units are safe for volatile, viscous or mildly corrosive liquids, are suitable for heating gases and can be used in either high or low pressure applications.
The CAST-X 2000's construction consists of a helically coiled tube cast into an aluminum body with tubular heating elements. The aluminum body is a seamless heavy wall that serves as the heat transfer media between the tubular element and the coiled tube through which the fluid being heated passes through. This non-weld construction minimizes material usage and offers a lower per package cost than traditional circulation heaters.
"The unique construction of this heater allows it to be used where thermally sensitive materials are being heated such as paints, resins and flammable materials," said Chris Baichoo, product manager. "The aluminum mass acts as a thermal flywheel and ensures accurate temperature control of the fluid to prevent degradation."
This new circulation heater is available with an integral thermostat that is also cast into the aluminum, which allows the heater to run dry without causing damage to the heating element.
The CAST-X 2000 is explosion resistant and prevents fluid contamination because the heated fluid does not come in contact with the heating element. "This is a performance requirement in foodservice equipment, semiconductor and analytical markets," adds Baichoo.
