Heat Transfer Fluids - MultiTherm PG-1

Non-Toxic
Promotes Plant and Personal Safety
MultiTherm PG-1? food grade mineral oil 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 Maintenance Costs
System downtime due to mechanical seal failure, sludge build-up or heater burnout can result in lost production time as well as extra direct maintenance cost. MultiTherm PG-1? can help reduce these costs. It has lubricating properties that reduce wear on mechanical seals and packing glands. The fluid is chemically inert and will not attack seals or gaskets. System cleaning is reduced since any carbon formed can be filtered or drained from the system. By eliminating maintenance problems, MultiTherm PG-1? helps reduce the costs.

With non-fouling MultiTherm PG-1?, these problems disappear. As it degrades, it produces small carbon particles that do not
stick to system surfaces, but remain suspended and are easily drained or filtered out. Since heat transfer surfaces remain clean, system performance remains constant.

Non-Fouling
Long Term Temperature Control
All organic heat transfer fluids undergo thermal degradation over time. Conventional synthetic fluids or low quality oils will form
soft carbon material (sludge) that eventually coats all system surfaces, and can form a hard coating. Because the coating acts as an insulator, heat transfer rates are reduced resulting in longer heat up time, lower production rates, changes in control response and, in extreme cases, burnout of heater tubes or electrical elements.

Lower Equipment Costs
Fluid properties can also affect equipment costs. Many conventional fluids have high viscosity at ambient temperatures and
can require oversized pumps and/or heat tracing equipment to facilitate cold startups. MultiTherm PG-1? is pumpable to
