Heat transfer fluids for -100ºC to 343°C, including several non-toxic fluids. Technical support focuses on preventive maintenance of the entire heating system. With six warehouses in North America, Paratherm can ship any time to prevent shut down of a line. Hot oil system cleaners restore system performance in a few weeks without shut-down, or overnight during system maintenance.

Unlike conventional heat transfer fluids, the Paratherm NF will not cause hard carbon formation on heated surfaces. Conventional heat transfer fluids, when severely overheated, will produce sooty carbon at the film layer. Much of this carbon immediately adheres to the heated surface and bakes on, forming a crust. As layer-upon-layer builds up, heat transfer - and in many cases flow - is impaired. Although nearly impossible to remove without scraping, sandblasting or using chlorinated solvents, the carbon can ultimately break loose, and large chunks of it can circulate through the system impeding flows and fouling components. Where fouling is extreme, heater tubing and electrical elements will stress and prematurely fail. Under similar extreme overheat conditions, the NF fluid evolves small carbon granules. These granules remain in suspension and are easily filtered out.

Users of Paratherm LR that switched from a silicone-based fluid have reported that the LR fluid will dissolve residual silicone oil in the system. Paratherm R&D has confirmed that the LR fluid will easily assimilate 5% silicone oil, by volume.

The Paratherm LR fluid is designed for a broad variety of cooling and heating applications. It is engineered to provide extended performance under rugged operating conditions, yet is easy and safe to handle.

Environmental Safety The LR fluid is plant-friendly and safe to use. The crystal-clear fluid contains no SARA1.- reportable substances such as chlorinated hydrocarbons, aromatics, heavy metals, or compounds of sulfur and nitrogen.

Fluid Toxicity The Paratherm LR fluid is non-toxic. And unlike other heat/cool liquids, it emits no pungent or noxious odors. Be sure to consult the Material Safety Data Sheet (MSDS) before using this product. This fluid is also rated food-grade by NSF.

Fluid Disposal Easy to dispose, used or contaminated LR fluid can be safely combined with spent lubricating oils and recycled locally (EPA, citation 57FR21524). Paratherm strongly encourages recycling of used heat transfer fluid to conserve natural resources and to minimize the problem of liquid waste in landfills. Please review local, state and federal regulations when you plan to dispose of any material. Liquids contaminated with chlorinated solvents or other regulated materials may require special handling, and may not be accepted by recyclers.

DOWFROST* HD heat transfer fluid is a formulation of 94.0 percent propylene glycol and a specially designed package of industrial corrosion inhibitors. The fluid is dyed flourescent yellow to aid in leak detection. Solutions in water provide freeze protection to below -60 °F (-50 °C) and burst protection to -100 °F (-73 °C).

Recommended use temperature range: -50 °F (-45 °C) to 325 °F (160 °C).

Suitable applications: single fluid process heating and cooling, closed-loop, water-based HVAC applications where propylene glycol solutions are preferred or required. Not suitable for food or beverage application.

Features:

• 20% Improvement in Flow Rate
• No Equipment Modifications
• 10°F Lower Operation, Same Viscosity
• Aerospace Testing Fluid
• Fine Chemical Processes, Pharmaceutical Production

The Paratherm CR^® (Patent Pending) heat transfer fluid provides predictable, repeatable performance in cryogenically-driven processes. Consistent properties improve productivity, and eliminate runaway coil freeze-ups. 10-cP viscosity @ -88ºC (20-cP @ -96ºC) brings higher efficiency at lower temperatures. Ease of containment and handling allow greater latitude in system design and component specification, and eliminate contamination and costly clean-up.

These advantages, combined with the fluid's unusually low freeze point of < -120°C, can lead to substantially shortened production times, improved product quality, better yields, and less hassle, when compared to d-limonene or silicone oil.
