Chromalox MWS - Mid-Size Water/Glycol System - is engineered to operate to 300°F (150°C) with either water or water/glycol fluids. Its electric heating core assures responsive and precise temperature control in a space saving package. The system is suitable for a large range of heating needs with a compact design. The MWS operates in a closed loop system using a cold expansion tank (optional).

Applications

Chromalox MWS system is great for applications such as reactors, evaporators, dryers, platen presses, heat excangers, roll heating, or any jacketed kettles / vessels / tanks.

Hot water systems can be used in a variety of industries such as chemical, plastics, cosmetics, automotive, rubber, refining, pharmaceutical, non-woven / textiles/ fibers, aerospace, or any other industrial market.

Construction

Chromalox MWS systems are ruggedly constructed for industrial applications. The heavy-duty, steel support base features channel grooves for forklift transport. The heater chamber is fully welded and houses Chromalox brand, long-lasting heating elements. The panel is fully UL-listed and assembled in-house. The pump is air-cooled with a mechanical seal, rated to 300°F (150°C). The final assembly is fully-shop tested prior to shipment.
