MultiTherm IG-4 Heat Transfer Fluid
Available from Multitherm LLC
MultiTherm IG-4® is a non-toxic durable heat transfer oil for use in closed loop, liquid phase heating systems up to 600°F.
MultiTherm IG-4 provides users with a safe, durable and economical heat transfer fluid without the potential hazards caused by some conventional fluids. IG-4 is a highly refined product with resistance to oxidation and thermal breakdown. It can take the stress without requiring premature replacement. Properties include high flash point, very low vapor pressure, oxidation resistant, non toxic and non hazardous.
The benefits of a low vapor pressure fluid are in the fact that the higher the vapor pressure, the greater the rate of fluid boil-off. Since MultiTherm IG-4 has exceptionally low vapor pressure, and excellent oxidation resistance, as a result, its service life is significantly longer under these severe conditions. MultiTherm IG-4® does not contain any component recognized as a hazardous chemical under the OSHA Hazard Communication Standard. IG-4 also offers the additional benefit of being an NSF approved Heat Transfer Fluid. IG-4 being a Paraffinic based oil that coats all system surfaces with a protective fluid film, it therefore provides outstanding lubricity for moving parts and also helps protect components from corrosion. Finally, MultiTherm IG-4 is generally more simple to dispose. Used, uncontaminated fluid can be treated as used lubricating oil, and handled through a local waste oil processor
