Dowcal fluids are inhibited glycols which offer exceptional corrosion protection for most metals which are used in heat transfer systems These fluids are widely used in food beverage and pharmaceutical operations with operating ranges between -50C and +175C for chilling or in Single Fluid Heating and Cooling processes
Using Inhibited Propylene Glycol for heat transfer applications instead of brine solutions or uninhibited propylene glycol reduces maintenance costs and improves heat transfer efficiency Outperforms Dowfrost and Ambitrol range of inhibited propylene glycol based heat transfer fluids Applications: Beverages Juices Breweries Distilleries Packaged Food Freezing Canneries Preservers
Paratherm LR low range heat transfer fluid has higher heat-transfer coefficients than 50% ethylene-glycol and 50% propylene-glycol solutions below -22F and -4F respectively And while glycol solutions have a maximum operating temperature of 320F Paratherm LR is completely stable up to it's 450F maximum operating temperature
Propylene glycol-based low temperature transfer fluids (PG-based LTTFs) are mixtures of propylene glycol with water corrosion and scale inhibitors and dyes They are much less toxic than heat transfer fluids based on ethylene glycol and can depress freezing points to as low as –60F (–51C) They are marketed by Dow under the trade names AMBITROL coolants DOWCAL fluids DOWFROST

Great Western Glycol was founded in 2003 and has grown to become one of the largest glycol recovery operations in the western United States The GWG facility includes over 450 000 gallons of tank capacity a vacuum distillation system and blending equipment A set of high-capacity certified scales ensures that bulk loads are accurately handled and transporters are assured of staying within
DOWFROST HD 40 HEAT TRANSFER FLUID DYED is a Propylene Glycol Based Heat Transfer Fluid manufactured by The Dow Chemical Company It is essentially comprised of Propylene Glycol of CAS No 57-55-6 at about 37 0 - 43 0 % and Water of CAS No 7732-18-5 at about 60 0 % and others Its physical state is of a liquid that appears as yellow to green liquid
Glycol-based heat transfer fluids must be diluted prior to use to provide adequate freeze protection and enhanced heat transfer characteristics For engine cooling and other industrial applications ethylene glycol (EG) is the glycol of choice ethylene glycol-based coolants are normally preferred over propylene glycol (PG)-based coolants because of their more desirable physical properties
Propylene glycol also has a higher viscosity than ethylene glycol which results in somewhat lower heat transfer efficiency and somewhat more difficult cold weather pump startup for propylene-glycol based fluids When diluting KOSTChill fluids KOST USA recommends the use of deionized or distilled water
Propylene and Ethylene glycol are commonly used heat transfer fluids for protection in Industrial and Commercial closed loop water based HVAC and cooling systems These glycols come in both inhibited and uninhibited but as you can see from the picture above better system protection can be achieved where a properly selected inhibited glycol is used
Coolant Antifreeze or Heat Transfer Fluids are designed to stop engine failures by preventing the inner engine parts from forming deposits Compatible with most variants of cooling systems with added inhibitor package It provides protection to brass copper solder steel cast iron aluminium alloys and other components such as rubber hoses gaskets rubber seals and plastic components that
For many heat-transfer applications it is necessary to use a heat-transfer fluid with lower freezing point than water The most common antifreeze fluid - ethylene glycol - must not be used where there is a chance of leakage to potable water or food processing systems In food processing systems the common heat-transfer fluid is based on propylene glycol
Propylene glycol (IUPAC name: propane-1 2-diol) according to the National Library of Medicine and Agency for Toxic Substances and Disease Registry is a synthetic liquid substance that absorbs water It is labeled an organic compound in chemistry due to its carbon attributes Its chemical formula is CH 3 CH(OH)CH 2 OH It is a viscous colorless liquid which is nearly odorless but possesses
The KOSTChill line of glycol based heat transfer fluids are engineered with glycols along with additive systems that have been tested and approved Depending on your application we can provide Ethylene Glycol (EG) Propylene Glycol (PG) Di-ethylene Glycol (DEG) Tri-ethylene Glycol (TEG) and NSF rated HT-1 Food Grade products Our heat transfer fluid manufacturers laboratory hassaved
Propylene glycol-based low temperature transfer fluids (PG-based LTTFs) are mixtures of propylene glycol with water corrosion and scale inhibitors and dyes They are much less toxic than heat transfer fluids based on ethylene glycol and can depress freezing points to as low as –60F (–51C) They are marketed by Dow under the trade names AMBITROL coolants DOWCAL fluids DOWFROST

EnviroGard™ inhibited propylene glycol based heat transfer fluids are categorized under Rhomar Water's Incidental Food Safe Glycol line of products All ingredients in these products are GRAS and these products are NSF registered EnviroGard™ antifreezes have a Gosselin Toxicity Index of 1 which indicates that it is "essentially non-toxic" and thus environmentally friendly These
Aluminum is a great material to use in a heat transfer fluid system however typical corrosion inhibitors may not be good enough to protect the product The pH of typical glycol-based heat transfer fluids is too high ( 9 0) Aluminum behaves well at a pH of 4 5 to 8 5 You can either adjust the pH of your fluid or add an aluminum corrosion
Propylene glycol and ethylene glycol are widely used in the HVAC industry to protect systems from damage caused by freezing and corrosion The primary difference between propylene glycol and ethylene glycol is toxicity and heat transfer characteristics Let us help you choose the right heat transfer fluid for the job
Using Inhibited Propylene Glycol for heat transfer applications instead of brine solutions or uninhibited propylene glycol reduces maintenance costs and improves heat transfer efficiency Outperforms Dowfrost and Ambitrol range of inhibited propylene glycol based heat transfer fluids
A non-hazardous reduced toxicity ethylene glycol-based antifreeze/heat transfer fluid concentrate is provided comprised of ethylene glycol an antidote for ethylene glycol poisoning such as propylene glycol and selected additives The antifreeze/heat transfer fluid concentrate may be combined with water to form a coolant solution for use in internal combustion engines
Zitrec F is miscible with the majority of conventional heat transfer fluids based on propylene glycol However to protect against corrosion we recommend using it without any mixing Zitrec F is a heat transfer fluid based on mono propylene glycol Zitrec FC should only be diluted with softened water
Paratherm LR low range heat transfer fluid has higher heat-transfer coefficients than 50% ethylene-glycol and 50% propylene-glycol solutions below -22F and -4F respectively And while glycol solutions have a maximum operating temperature of 320F Paratherm LR is completely stable up to it's 450F maximum operating temperature Stability tests showed less than 3% degradation after 500
Hydratech Propylene Glycol based heat transfer fluids are formulated to operate in both cooling and heating systems at a wide range of concentrations To provide protection over a long period of time the initial mixture must also have the right balance of corrosion scale and biological inhibitors in order to maintain proper corrosion control at various concentrations The inhibitors in
Chemical based heat transfer fluids can also be based on several chemicals including silicone terphenyl and alkylated aromatic compounds Be aware that chemical composition impacts how suitable a fluid is for an application So correctly matching the fluid to the system and application can help preserve fluid life in addition to a robust approach to condition monitoring and maintenance You
