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 System Cleaner
DuraClean 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 the fluid at 150°F (66°C) until the system is deposit-free, drain thoroughly and refill with fresh heat transfer fluid.

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.

Propylene Glycol Fluid
Safe-T-Therm is an inhibited propylene glycol designed to protect metals such as brass, copper, solder, steel and cast iron. The fluid’s formula also includes an orange dye for leak detection and an antifoam agent to minimize foaming during service. Using the propylene-glycol based fluid in place of brine solutions or uninhibited glycol/water solutions can lower maintenance costs and improves heat transfer efficiency.

Heat Transfer Fluid with Corrosion Inhibitors
Oxygen and heat transfer fluid surface contact in a system’s expansion tank or elsewhere can cause metal corrosion and acidity. Xceltherm 500M inhibits the ability of oxygen to damage system components and the fluid, especially when materials of construction such as copper or brass are present. With an operating range of -80 to 500°F (-62 to 260°C), it can be used for heating or cooling. The operating temperature range allows a system designed for water to run at higher temperatures without pressure by switching to a hot oil product.
