MultiTherm 503® process heating and cooling in standard low pressure equipment

MultiTherm 503® is a high quality non-toxic heat transfer fluid for use in closed loop liquid phase heating and cooling systems from 10°F to 500°F.

 

Purpose
MultiTherm 503® has been successfully used in a variety of applications. In the Chemical Process Industry, it has been used for heating and cooling batch reactor systems. In the Plastics Industry, MultiTherm 503® has been used for hot/cold cycling of molded products and to improve the versatility of laminating lines. MultiTherm 503® provides users with a non-toxic, low pressure alternative to synthetic chemical based heating/cooling fluids. MultiTherm 503® meets the requirements for FDA regulations 21CFR178.3620(b) non-food articles in contact with food.

 

MultiTherm 503® provides users with a safe, durable and economical heat transfer fluid without the potential hazards posed by some conventional thermal fluids.

 

Non-Toxic
Promotes Plant and Personal Safety
MultiTherm 503® has distinct advantages over many synthetic heat transfer fluids. It contains no components recognized as Hazardous Chemicals under OSHA Hazard Communication Standard. There are no Reportable Substances under SARA Title III (302) (304) (311) (312) (313). The fluid does not normally cause skin irritation on contact. Vapors may have a mild odor but do not normally cause respiratory irritation. All these advantages combine to provide a safe, user friendly alternative to synthetic fluids.

 

Lower Costs
Reduced Maintenance Costs
MultiTherm 503® can help reduce system maintenance costs. It has excellent metal coating properties and lubricity, which reduce wear on moving parts and protects surfaces from corrosion. Chemically inert, it won’t attack gaskets and seals. And since MultiTherm 503® operates in low pressure equipment, there are no pressure control or purging systems to maintain. Minimize Leak Testing Fluids with high vapor pressure can require extensive leak testing prior to start-up to prevent fluid loss during operation. This can add significantly to total maintenance down time. With MultiTherm 503®, system pressure is limited to pump circulating pressure so leak testing requirements are significantly reduced.
