MultiTherm IG-4® is a non toxic durable heat transfer fluid for use in closed loop, liquid phase heating systems up to 600°F.

A variety of industries benefit from the use of our Multi-Therm IG-4 Heat Transfer Fluid. In the Chemical Process Industry, MultiTherm IG-4 is used in central hot oil systems for heating all types of process equipment and products. In Asphalt Storage Facilities, the fluid is used for line tracing and tank heating. Die Temperature Control Systems benefit from its clean operation and high flash point. In Commercial Laundries, MultiTherm IG-4 provides higher throughput with a greater degree of safety in flat work ironers.

Non Toxic/Non Hazardous MultiTherm IG-4 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 IG-4 offers several advantages over many synthetic heat transfer fluid products. The fluid does not contain any chemical components recognized as hazardous under the OSHA Hazard Communication Standard. Moreover, there are no reportable substances under SARA Title (302), (304), (311), (312), and (313). Further, the fluid rarely causes skin irritation on contact and it rarely causes respiratory irritation due to fluid vapors that may be present. These advantages add up to afford a safe, user-friendly alternative to synthetic chemicals and products.

Easy Disposal

MultiTherm IG-4 is generally simpler to dispose of than many synthetic thermal liquids and toxic cleaning chemicals. Used, uncontaminated fluid can be treated as a used lubricating oil, and handled through a local waste oil processor. Check with all applicable regulations in advance.


MultiTherm LT-112 ® is the ideal choice when heat transfer fluid requirements demand both low toxicity and an elevated flash point. With its proven record of environmental safety and affordable pricing, MultiTherm LT-112 ® is one of the most effective heat-transfer fluids on the market for most mid to low range applications.

DURABLE

Closed Loop Systems

Closed loop, liquid phase heat transfer systems often operate for extended periods of time with little or no problems. However, equipment malfunctions such as circulating pump failures, bypass valve malfunctions, and cracked heater tubes can put extra stress on the heat transfer fluid. If the fluid has been in service for a period of time, and especially if it has been exposed to air at high temperature, these malfunctions can cause rapid degradation and require immediate replacement to prevent further equipment problems. MultiTherm IG-4 is a highly refined non toxic product with resistance to oxidation and thermal breakdown. It can take the stress without requiring premature replacement.

Open Systems

Oxidation and fluid boil-off are major problems when using organic heat transfer fluids in hot open systems. Oxidation produces organic acids which can polymerize and create deposits. The rate of boil-off is dependent on the fluid vapor pressure. The higher the vapor pressure, the greater the rate of fluid boil-off. 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. In an open tank, MultiTherm IG-4 should not exceed 350°F/(177°C).

HIGH FLASH POINT

In certain applications, local, state or federal regulations may require that the thermal fluid system operate below the fluid flash point. This can result in the need for greater heat transfer surface area (more equipment expense) to achieve required heat loads. MultiTherm IG-4 has one of the highest flash points of any heat transfer fluid (440°F / 227°C). This provides maximum system efficiency.

LOWER COSTS

Reduced Equipment Costs

Basing equipment design on MultiTherm IG-4 can reduce equipment costs. Its extremely low vapor pressure eliminates the need for pressurized expansion tanks to prevent pump cavitation and can allow specification of lower cost, low pressure piping and process equipment. VOC emissions are not normally a problem with MultiTherm IG-4 since system pressures are low and fluid vapor pressure is very low.

Reduced Maintenance Costs

MultiTherm IG-4 is based on a paraffinic oil that coats all system surfaces with a protective fluid fil
