Do you always wonder how beer stays cold when there isn ’ t a cool around ? Or how it maintains temperature after traveling hundreds of feet ? Yep, it ‘s kept cold by a ethylene glycol hair-raiser. This amazing patch of equipment handles the job of keeping beer cold after it leaves a cool and is poured from a draft beer tugboat. After this article, you will understand all you need to know about beer ethylene glycol chillers and how they work.

What Does a Glycol Chiller Do?

A ethylene glycol hair-raiser handles keeping beer, inside a beer luggage compartment line cold as beer leaves a walk-in cooler.Beer trunk lines can vary depending on unlike dispense variables and the length of the beer run. Wherever the beer needs to go … it needs to be cold. so beer doesn ’ deoxythymidine monophosphate foam when it ’ sulfur dispensed and the owner of the beer system can maximize their keg move over .Picture of a Glycol Chiller

How Does a Beer Glycol Chiller Work?

Glycol chillers work by cooling a diol bath of ethylene glycol, which is antifreeze. then taking that cooled ethylene glycol and pumping it through the beer trunkline, and beer loom before returning rear to the diol hair-raiser. There are unlike types of diol chillers, but most used for draft beer applications are ⅙ horsepower up to 1.5 horsepower. The reservoir on the ethylene glycol units can vary from 5 gals up to 15 gals. The larger the compressor on the hair-raiser, the longer beer run it can cool. For example, beer runs can be a few feet to over 500 feet. The ethylene glycol hair-raiser is able to cool these beer runs with a larger compressor and larger diol bath, or reservoir. There ’ s a thermostat that sits inside of the ethylene glycol bath which monitors temperature. I normally set most of the chillers to around 28-30 degrees F. Chillers are normally set at 28 F coming from the manufacturer. They have a digital thermostat on the front, which makes it easy to view and change from the dominance gore. once, the ethylene glycol chillers are running and pumping diol through the conscription beer organization. They keep running 24/7. Until parts or glycol need servicing or replaced .Picture of 1/3 Hp Glycol Chiller

What Type of Glycol is Used for Chillers?

Glycol that is used for beer chillers is propylene diol .

What is Propylene Glycol?

It ’ s a food-grade antifreeze, non-toxic diol that ‘s used in the food and beer industry. It ’ s kind of despicable to the touch and is besides a lubricant for the pump on the hair-raiser. One gallon of propylene ethylene glycol will mix with 2.5 gallons of water. This achieves the optimum desegregate. once filled with ethylene glycol that hair-raiser can turn on. When turned on you ’ ll notice the diol viewing glass charge drops. It does this because the ethylene glycol is being sent out to the beer tugboat. once the ethylene glycol returns, top off the hair-raiser until the diol submerges the copper coils inside the reservoir. last, make sure to plug the reservoir hole. You don ’ deoxythymidine monophosphate want to leave the ethylene glycol bathe open because the water can evaporate from the blend making it harder for the diol to pump .

Glycol Beer Chiller and Draft Beer Application

Chillers are used in a outback administer scenario. All this means is that when beer needs to get to beer towers farther away than where their beer cooler chillers needed. anything outside of a beer cooler needs to be cold via a beer hair-raiser. Remember the purpose of the hair-raiser is to keep beer cold until it ‘s dispensed at 38 degrees F .Picture of Perlick Glycol Chiller

Different Types of Glycol Chillers

There are few different types, but I am going to talk about draft beer diol chillers / Power packs. so let ’ s get this thing going …

Air Cooled Chillers

The most popular of the chillers. These use a sports fan to cool off the condenser and rest in well-ventilated areas on racks next to a walk-in cool .

Water Cooled Chillers

pretty a lot the lapp thing as above with the exception that the unit uses running body of water. These units are best for tight spaces, heavy humidity areas and tend to last a little longer than the air-cooled chillers .

Different Sized Chillers

Glycol Chillers can range from 1/6th horsepower up to 1.5 horsepower for draft beer systems. The larger the compressor size, the longer a beer guide can be cold. typically, a ½ horsepower hair-raiser can run a 200 ’ beer race. ¾ Hp can run 350 ’ beer luggage compartment line and 1 horsepower normally around 500 ’ beer trunk lineage. Most of the larger chillers like the ¾ horsepower, 1 horsepower and 1.5 hp have larger reservoirs which help keep the ethylene glycol cold for longer beer runs .

Many Pump and Motor Chillers

Some chillers will come with a individual heart and motor on the diol unit. Usually it ’ s a ⅓ horsepower drive that drives a pump proper adjacent to it. This pump drives diol from the reservoir into the trunkline and spinal column to the reservoir nonstop. however, sometimes there are many beer stations and multiple beer runs that need to be cooled. frankincense, we need multiple pumps and motors on jobs. A single pump can cool a 8+2 trunkline. What this means is 8 products for beer and 2 lines for diol. Glycol supply and return cable. now, if the trunk line was a 10+4 trunkline and 200 ’ long. The hair-raiser would need two pumps and motors. Each pump and motor would run 1 supply credit line and 1 recurrence Glycol production line .Picture of a remote Beer system components Another scenario for many pumps and motors would be 3 bar stations that have 6+2 proboscis trace. Each pump and motive would feed each trunking going to its designated measure station. sometimes if the trunkline is short adequate and the size of the compressor is large adequate on the ethylene glycol unit. You would be able to loop the bundles together, but most of the time we will choose each run to its own pump and centrifugal .

Different Brand Glycol Chillers

In my know, I ’ ve used ethylene glycol chillers from a few different manufacturers. such as Banner, Perlick, UBC and Micro Matic. I ’ ve worked more with Micro Matic, UBC and Perlick. If you were to ask me which brand would I go with it would say Micro Matic. Over the years installing diol chillers … I can alone recall 2 times I ’ ve had issues with Micro Matic chillers and the problems was resolved .

Glycol Beer Chiller Maintenance

Change glycol annually for optimum performance. You are besides going to want to monitor every month and check the levels. The biggest thing is making certain ethylene glycol is covering the coils inside the reservoir. Check and clean the condenser fins every two months. These normally build up with dust particles and you want to make certain the airflow to the unit is unobstructed. last, listen to the unit … is it humming around the day you got it great. If there are some abnormal noises coming from the whole, it ’ sulfur best to get it serviced .


These are the chief things to look at and understand when it comes to glycol chillers inside a beer system. It ’ south one of the most important parts of a beer system.
