Purpose

MultiTherm® is offering an economical alternative for heat transfer fluid users.
MultiTherm IG-1® is a highly refined; hydrotreated mineral oil designed primarily for use in closed loop heat transfer systems.
MultiTherm IG- 1® is designed for use in systems that are equipped with expansion tanks, and it is recommended to have pressure relief valves and an inert gas blanket on the system. In properly designed systems it will provide trouble-free, long lasting service.

Applications

MultiTherm IG-1® is an excellent heat transfer fluid used in numerous industries that are looking for an economical heat transfer fluid for various manufacturing processes. Common applications for MultiTherm IG-1® heat transfer equipment used in manufacturing of asphalt shingles and roofing compounds, road-paving equipment, die-casting, paper and particle board.

Closed Loop Systems

MultiTherm IG-1® is designed for use in liquid-phase heat transfer systems, which are "closed" to the atmosphere. Where practical, it is recommended that there be an inert gas blanketing the systems expansion tank to guard against exposure to air and water to reduce the need to change-out the fluid prematurely.

MultiTherm IG-1® heat transfer fluid is designed with a maximum film temperature of 600°F and a maximum bulk temperature of 550°F.

Low Vaopr Preassure

MultiTherm IG-1® heat transfer fluid has a low vapor pressure compared to other economical heat transfer fluids. This is important because fluid boil-off is an issue in open systems. The rate of boil-off of a heat transfer fluid is dependent on the fluid vapor pressure. The higher the vapor pressure, the greater the rate of fluid boil-off.

High Flash Point

MultiTherm IG-1® also offers the benefit of having a high flash point of 442°F / 228°C compared to other economical heat transfer fluids on the market
