What temperature should a glycol machine be?
Different applications call for different temperatures, but generally, most breweries set their glycol chiller temperatures at 28-30° F, while wineries typically set theirs at 30-35°F.
Can you use a glycol chiller for distilling?
Glycol cooling is typically required in most distilleries. It plays a vital roll in all processes from mash cooling through the fermentation process and then during the distilling process.
How cold does a glycol chiller get?
The coldest temperature will depend on the size of the chiller and the ratio of glycol to water. For example, a light industrial chiller can fluctuate from 65°F (18.3°C) to 15°F (-9.4°C). Ultra-low deep freeze chillers can achieve freezing temperatures from a high of 70°F (21.1°C) down to -112°F (-80°C).
What is a glycol chiller used for brewing?
What Is a Glycol Chiller? Brewery glycol chillers are cooling units that utilize propylene glycol (an organic anti-freeze agent) or a mix of propylene glycol and water to extract excess heat from a brewing process and dissipate it in a heat exchanger or refrigeration system.
How often should glycol be changed?
“Some of our customers have had the same glycol in their systems for thirty years, some have had to replace or add after only five years – it’s totally unique to the facility.” However, HOH recommends testing at least once a year to ensure that proper levels are being maintained and that you really are protected.
Why is glycol so expensive?
A raw material supply crunch and buoyant demand from the pharma industry pushed up the price curve of Propylene Glycol.
How do you make a homemade glycol chiller?
Steps To Making Your Own Glycol Chiller
- Step 1: Tear the AC unit apart.
- Step 2: Disconnect the thermostat.
- Step 3: Unbolt the fans.
- Step 4: Bend the copper tubings and fit the condenser in your cooler.
- Step 5: House the Glycol System.
- Step 6: Cut holes for the glycol hoses.
- Step 7: Load your glycol and water mixture.

Can algae grow in glycol?
Using inhibited glycol in your system will prevent scale and corrosion from forming, algae and bacteria will not grow and metals such as copper, brass, steel cast iron and aluminum are protected. However, there are some things to know when using glycol in your chiller that if not followed properly, problems may follow.
Can you mix different brands of glycol?
Different brands or types of glycol should never be mixed, due to the different corrosion inhibitors used by different manufacturers. If topping up an existing system, only use the same brand that was originally installed.
What are the 2 types of glycol?
There are two main types of glycol used for this function: ethylene and propylene.
How long does glycol last?
Does glycol expire? Inhibited glycols have an indefinite shelf life if they are stored at ambient temperature and not exposed to direct sunlight. Uninhibited (plain) glycols have a shelf life of two years.
What is glycol used for?
It is most commonly used as antifreeze in automobiles, brake fluid, HVAC Systems, and some human-made fibers. It is derived from ethylene oxide, which comes from ethylene.

How does air cooled chiller work?
An air-cooled chiller works by absorbing the heat from processed water. Once the water in the air handler system is used, it becomes warm and is sent back to the chiller. Heat is transferred away from the water using the chiller’s evaporator.
Does ethylene glycol degrade over time?
Ethylene glycol can also enter the environment through the disposal of products that contain it. Air: Ethylene glycol in air will break down in about 10 days. Water and soil: Ethylene glycol in water and in soil will breakdown within several days to a few weeks.
Can I mix ethylene glycol and propylene glycol?
Though both are glycol compounds, ethylene and propylene cannot be mixed because they have different fluid, toxicity, and heat transfer properties that would prevent a system from working properly.
Which is better ethylene or propylene?
The difference between Propylene Glycol and Ethylene Glycol in antifreeze comes down to both toxicity levels and efficiency of performance. Ethylene glycol possess far superior heat transfer properties whereas Propylene Glycol carries a very low toxicity.
Why do you mix glycol with water?
Adding glycol to the water helps prevent both freezing and bursting, depending on the type of glycol used and its concentration. Freeze protection prevents the water from freezing, allowing it to continue to flow.
Is glycol harmful to humans?
Ethylene glycol has a sweet taste and is often ingested by accident or on purpose. Ethylene glycol breaks down into toxic compounds in the body. Ethylene glycol and its toxic byproducts first affect the central nervous system (CNS), then the heart, and finally the kidneys. Ingesting enough can cause death.
Why is ethylene glycol toxic to humans?
Ethylene glycol’s toxicity mainly results from the accumulation of its toxic metabolites. Ethylene glycol is a central nervous system (CNS) depressant that produces acute effects similar to those of ethanol. These CNS effects predominate during the first hours after exposure.
What should chilled water pressure be?
Generally, most chilled water systems operate at a pressure of around 10-12 bar. Some chilled water systems work at more than 16 bar of pressure but they rarely exceed 20 bar. High pressure chilled water systems usually use heat exchangers to reduce the pressure to below 20 bar.
How much pressure is in a chiller?
The refrigerant is sucked into the compressor from the evaporator as a cold, low pressure gas at 1.91 barg. It is then compressed into a hot, high pressure gas which is discharged from the compressor at 8 barg.
