Heat Transfer Oil: RPL-HT1000

Product Description:

RPL-H1000T heat transfer oil is special formulation designed specifically to aid in the rapid and efficient transfer of heat away from critical hot spots in severe applications. It has excellent oxidation stability and exceptional resistance to thermal decomposition. It also has low volatility which helps eliminate vapor lock in circulating pumps and reduces the risk of cavitations which are destructive to centrifugal pump blades.

Features and Benefits:

• Rapid, efficient transfer of heat

• Can be used up to 365F (185C) in open systems (exposed to the atmosphere)

• Can be used up to 600F (315C) In closed systems (not exposed to the atmosphere)

• Excellent oxidation stability and resistance to thermal decomposition

• Low volatility

Typical Applications:

• Asphalt and coal tar storage, transport and compounding

• Dyes, chemicals and pharmaceutical manufacturing plants

• Lumber drying

• Paper and paperboard production

• Petroleum products processing

• Plywood laminating

• Rubber and plastic molding, extrusion, curing and calendaring

• Sheet metal laminating

• Solar energy heat transfer and storage

• Textiles (hot calendaring)

• Tiles, linoleum and roofing products

• Varnish and resins manufacturing
