Heat Transfer System CleanerDuraClean Ultra is capable of cleaning sludge, coke and varnish from expansion tanks, reservoirs, processes and piping within a few hours. The heat transfer system cleaner has a light odor but maintains the aggressive cleaning action found with caustic solutions and chemical solvents. Engineered to clean quickly with minimal labor and downtime, users simply drain the existing fluid from the entire system or just the troublesome areas, circulate at 150°F (66°C) until the system is deposit-free, drain thoroughly and refill with fresh heat transfer fluid.

Thermal Heat Transfer FluidMultiTherm PG-1 is a nontoxic, colorless and odorless food-grade heat transfer fluid that has an operating temperature above 600°F (316°C). In the food processing industry, the heat transfer fluid is used in indirect heating loops for frying and baking. It is acceptable for use as a heat transfer fluid in plants operating under the Federal Meat and Poultry Inspection Program. It does not contain any components recognized as hazardous chemicals under OSHA Hazard Communication Standard. Also, it is also FDA certified, USDA acceptable, NSF HT-1 approved for incidental contact, Kosher certified, and food certified in Canada.

System Cleaner Liquid Dissolves Sludge
Paratherm LC liquid restores thermal fluid system performance on the fly. Cleaning while the system operates, it dissolves and suspends sludge deposits that can reduce flow - and thus heat transfer - in larger continuously operated hot-oil systems. Compatible with mineral-oil-based fluids, it operates while the system does, eliminating the downtime and extra handling and disposal involved with flushing fluids or chemical cleaning agents.

Heat Transfer Fluid
Purity FG is a food-grade fluid that provides high thermal efficiency in systems operating up to 620°F (326°C). The heat transfer fluid’s chemistry can extend fluid life and can lower operating costs by reducing the frequency of fluid change-outs. Typical applications include drying, central cooking facilities, edible oil deodorizing and the heating of deep frying oils. The fluid also may be used in heating baths where an odorless, nonhazardous fluid is required for worker health and safety.

Heat Transfer Fluids
Therminol heat transfer fluids meet the requirements of most chemical processes. Each chemical process has unique operating parameters that can be used by a design or process engineer to select the heat transfer fluid that will result in the best total performance. Therminol 55 can be used when only moderate temperatures are needed. Therminol 59 is best when combination heating and cooling conditions are present. Therminol 66 liquid-phase heat transfer fluids, as well as Therminol VP-1 and Therminol VP-3 vapor-phase heat transfer fluids, are preferred when high operating temperatures are required.
