Protec heat exchanger are designed to fit within the solution tank.  The use of steam or hot water flowing within the the tubes of the exchanger will transfer heat from your source to the liquid within the tank. Temperature control is obtained by controlling the flow of liquid through the heat exchanger.   These exchanges can also be used for cooling applications.

TherMax Heat Exchangers

Process Technology’s TherMax² Heat Exchanger is a state-of-the-art in-line stainless steel exchanger for deionized water and process solutions. This revolutionary design is constructed of a 316L stainless steel jacket and spiral bundle. Internal silicon baffles and a dimpled spiral sheet route water in a rotating circular motion, resulting in high heat transfer (other baffle materials are available to suit your specific needs). The heat transfer surface of the TherMax² enhances turbulence with low pressure drops, producing heat transfer rates 3 to 4 times that of tubular heat exchangers.

The all-welded construction provides not only long life, but easy installation as well. There are numerous applications for the unit including industrial, process system, cogeneration, solar, plating, electronics, commercial and industrial washers, evaporators/condensers, chillers, heat recovery, boilers (steam and water), vapory recovery, and water heaters.

Ideal for Electroless Nickel Applications

Seven sizes available in the TherMax² - Compact cylinders from 3 inches (70 millimeters) by 6 inches (158 millimeters) to 5 inches (120 millimeters) by 20 inches (515 millimeters). Weight, from 2.4 pounds (1.1 kilograms) to 31 pounds (14 kilograms).
