10 Glycol Tips for Water Chiller OperatorsThe use of an industrial inhibited glycol and water mixture is recommended in most water chiller systemsEthylene and Propylene are the two standard types of inhibited glycols commonly usedThe main job of glycol is to prevent freezing of the process fluid and ensure consistent flow at the operating.
Chillers use glycolwater mixtures to provide cooling to products and materials that need to be kept at a low stable temperatureGlycol manufacturers such as Du Pont are required by law to provide a glycol level recommendation chart to consumers.
Moreover does glycol improve heat transfer Ethylene glycol and propylene glycol have higher vapor points and therefore can absorb heat at higher temperatures without boilingYet even with its lower vapor point water still carries more heat per unitA larger tube also has more wallsurface area resulting in improved heat transfer.
Dec 02 2021nbsp018332What is a Glycol Cooler A glycol chiller is a type of refrigeration system that uses a fluid to circulate coolantThis fluid is either water or a mixture of water and glycol a mixture of ethylene glycol and waterThe process can be divided into three parts 1 The highpressure pump circulates liquid around the coils through the heat.
Dec 03 2019 By implication glycolbased chillers are better suited to lowtemp environmentsConversely water has a better ability to retain and conduct heat from an associated process than a glycol mixture canAs a result the efficiency of heat transfer for a water chiller will be higher than that of a glycol chiller.
Dowtherm SR1 is the Industrial Grade Ethylene Glycol that we specify for use in our chillersThe glycol is an ethylene glycol blend without the silicone and a full array of system corrosion and rust inhibitorsIn short it is designed and made specifically for chiller systemsIt is available in a wide variety of blends and we ship it to.
Ethylene and Propylene Chillers Ethylene EG GlycolEthylene glycol is an antifreeze used in industrial cooling units to protect against freezing and as a rust inhibitorThe percentage of ethylene glycol used in a glycol and water mixture is determined by the lowest outdoor ambient temperature and the temperature of the application loop.
Ethylene glycol is an antifreeze product used in industrial glycol cooling equipmentIts primary use is in industrial cooling applications as freeze protection and rust inhibitingThis growth can only be credited to the years of hard work gaining the trust of its customers which include end users OEMs suppliers distributors.
Ethylene glycol is an antifreeze product used in industrial glycol cooling equipmentIts primary use is in industrial cooling applications as freeze protection and rust inhibitingPercentage of glycol used can be determined by a location’s lowest outdoor ambient temperature and also the temperature of the process application loop.
Ethylene glycol a derivative of ethylene oxide is used for the manufacture of polyester fiber for clothes upholstery carpet and pillows and the blending of automotive engine antifreeze and coolantEthylene glycol is also used to manufacture fiberglass for products such as jet skis bathtubs and bowling ballsA major use is in the production of polyethylene terephthalate PET resin a recyclable plastic such as soda and water bottles.
Glycol can be purchased from reputable vendors including Chase Cooling SystemsWhen purchasing glycol know the concentration you need and the concentration you are purchasingGlycol comes in stock concentrates as well as in set blendsIt can be ordered in 55 gal drums 5 gal pails or bulk 275 gal totesAlways make sure you are purchasing the appropriate grade glycolAutomotive antifreeze should never be used in a chiller.
I figured that would be the case but since I have access to some of the red stuff I wasnt sure if it compatible with a computer cooling systemHowever all my radiators on my intended cooling system are made of copper.

Jul 01 2021nbsp018332The fundamental difference between the two types of chillers is the change in their freezing point and thermal conductivityThe freezing point of pure ethylene glycol or a mixture of ethylene glycol and water is much lower than that of pure waterThis means that glycolbased chillers are more suitable for lowtemperature environments.
Jun 26 2020 Ethylene glycol does have a relatively high toxicity so its use in food applications like beverage production is often frowned uponPropylene glycol has a much lower toxicity and still has relatively good heat transfer qualities and low viscosity which makes pumping easier so it is the chemical of choice for many of these applications.
Jun 26 2020nbsp018332We recommend using glycol solutions up to 50 to operate chilling systems down to 4F 20C but for operating temperatures below this we tend to recommend moving away from glycols to other heat transfer fluidsThis is mainly due to the high viscosities that come about from increasing glycol mixture percentages and reduced operating.
Mar 06 2020 Glycol chillers can be operated using either propylene glycol or ethylene glycolMost food production companies and restaurants use propylene glycol in their chillersHow do glycol chillers work Glycol chillers work by circulating the cold fluid from the refrigeration unit—the chiller—to the target area or fixture such as a freezer.
Mar 23 2017nbsp018332Scanair Glycol Chillers are latest in technology engineered and designed for demanding process of glycol cooling applications that will maintain the temperature range from – 20 o C To 30 o C 177 1 o C Capacity from 500 KcalHr to 150000 Kcal Hr from 05 LPM To 120 LPM with different flow capacity.
May 01 2003nbsp018332Never use car antifreeze in a chiller systemThe additives found in this type of antifreeze will foul heat exchangers and result in poor heat transferThere are two basic types of glycol used in process chillers ethylene and propyleneThese glycols are available in temperature ranges of 60 to 350 o F 51 to 177 o C and work well for.
May 02 2019nbsp018332Chemical UsesGlycol HOCH 2 CH 2 OH is a mildly toxic chemical that alters the freezing temperature of waterAccording to the American Chemistry Council ethylene glycol commonly referred to as glycol is used for process cooling in many industries.
Sep 17 2019nbsp018332North Slope Chillers recognizes the unique requirements that individual businesses have in process cooling especially when using glycolGlycol heaters and chillers are tantamount to achieving the best resultThat’s why each chiller system is created to be the solution to specific temperature control problemsChillers can be custom ordered.
The chemical formula for ethylene glycol is C 2 H 6 O 2 and its molecular weight is 624 Ethylene glycol occurs as a clear slightly viscous liquid that is completely miscible with water145 Ethylene glycol is odorless3 The vapor pressure for ethylene glycol is 0.
Though not a glycol manufacturer North Slope Chillers is an expert in the use of propylene glycol in chiller systemsFor more information about glycol concentrations click here.
When it comes to using glycol heaters or chillers propylene glycol is the most important chemical when you have to balance cooling a product and preventing water from freezingWhen mixed with glycol water freezes at lower temperatures allowing for cooler liquids to flow through a chiller system without the danger of the system freezing up.
There are two types of glycol commonly used for process chillers Propylene and Ethylene GlycolThese products vary on metrics such as performance environmental factors and general safetyThe specific needs of your process will determine which glycol type is best for your system.
