Manufacturers Find New Ways to Keep Cool

New, newer, and newest heat transfer fluids rescue low-temperature processes.

A fine-chemical producer in Georgia needed a low-temperature heat transfer fluid to replace the flammable-rated product in their reactor loop. A fragrances and pheromones firm in New England needed much lower temperatures than their citrus-derived fluid was capable of delivering. And a pharmaceutical manufacturer in Puerto Rico needed a non-aqueous food-grade thermal fluid because the specified glycol/water solution couldn’t deliver the cooling capacity the process demanded.

All three companies needed heat transfer fluids better suited to the specific requirements of their cooling processes.

Over the past two years, Paratherm Corporation, a long-time manufacturer of high-temperature heat transfer fluids, has developed a new line of lower-temperature transfer fluids, and these products filled the technical needs of all three processors.

The newest, Paratherm MG™ mid-range fluid is a food-grade non-aqueous heat/cool fluid that eliminates the significant design and operational problems found in steam/chilled-water systems. The fluid, now installed in the Puerto Rico application, is recommended for processes operating from 0°C to 260°C.

Processors with more severe low-temperature requirements are discovering the unique qualities that distinguish Paratherm LR™ Heat Transfer Fluid. This food grade (NSF approved) fluid operates between -40°C and +204°C. Its over 60°C flashpoint allows it to be classified as Combustible rather than Flammable, reducing safety concerns. Chemical, cosmetic, and electronic-materials manufacturers have replaced Silicone-based, glycol/water, and other fluid chemistries with the Paratherm LR fluid. This is the fluid that solved problems in the fine-chemicals plant in Georgia.

Paratherm’s cryogenic-range Paratherm CR™ heat transfer fluid (Patent Pending) was specifically developed to provide the ultra-cold process temperatures (down to -100ºC) pharmaceutical and fine-chemical manufacturers need to increase product purity while simultaneously cutting production time. The low viscosity permits higher fluid turbulence, resulting in faster heat removal than silicone liquids or d-limonene-based fluids. These benefits are providing operational and competitive advantages to the pheromone and fragrances producer in New England.

Paratherm Corporation's product line has grown to seven heat transfer fluids and two high-performance system-cleaner liquids, but the service mission of Paratherm Engineers and Staff has remained the same; to use their thorough knowledge and experience with thermal systems and heat transfer fluids, their relationships with heater and equipment manufacturers, and their focused attention on the needs of customers, to deliver smoothly operating systems and applications, and maximum production, to processors that choose Paratherm.
