Chromalox MOS Mid-Size Hot Oil System is engineered to operate to 600°F (315°C) standard, with an option for up to 650°F (343°C), at atmospheric pressure (non-pressurized). Its electric heating core assures responsive and precise temperature control in a space saving package. The system can be used with most types of heat transfer oils such as Paratherm®, Mobiletherm®, Therminol®, Dow Brands®, etc. The MOS operates in a closed loop system using a cold expansion tank (optional). A cold expansion tank can remove the need for a nitrogen (N2) purge and reduces the degredation of heat transfer fluids.

Applications

The Chromalox MOS system is great for applications such as reactors, evaporators, dryers, platen presses, heat exchangers, roll heating, or any jacketed kettles / vessels / tanks. Hot oil 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 MOS 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 only Chromalox brand, long-lasting heating elements. The panel is UL-listed and assembled in-house. The pump is air-cooled with a mechanical seal, rated to 650°F (343°C). The final assembly is fully-shop tested prior to shipment.
