The glycol chiller is indispensable equipment for pubs and restaurants. It allows pubs to extend the beer passage from the storage place to the beer rack. Also, it creates a special aesthetic appearance due to the freezing of beer columns. The glycol pump is a critical element of this cooling system and needs to be replaced periodically.
How the Glycol Beer Cooling System Works
The most important element of the glycol pump system for beer is the glycol reservoir, to which the glycol pump is connected. It is no coincidence that it is called the heart of this entire cooler because it pumps glycol through a special tube to a beer python. The whole system consists of the following main elements:
- Beer kegs that are kept in a remote storage
- Beer hoses that are attached to kegs
- A glycol cooler that contains glycol and water and sends them with a glycol transfer pump through special tubes to the beer python or beer trunk line
- Beer Trunk Line, which alternates water and glycol pipes (usually 2 to 4) and beer pipes. They go directly to the beer pouring points
- Draft Beer Tap Towers through which beer is poured directly to visitors
What Are The Advantages Of Glycol Chilling System
You can choose other ways to cool beer, for example, water or dry, but the advantages of glycol equipment are undeniable:
- This is the best option for long beer lines exceeding 15 feet. And if this line is over 65 meters, then there are simply no other chilling options
- It is possible to spread beer skittles in the storage and spill points as far as 600 feet, so this is ideal for stadiums and other large venues
- Yeast and bacteria growth does not occur due to the fact that the beer remains chilled throughout the all beer trunk line
- The glycol-water mixture, unlike water, does not freeze below 0°C, and therefore can easily circulate through the system
- Frosted beer columns are very impressive for pub visitors
- After the pub is closed, it is not necessary to drain the beer from the beer lines, since it will be chilled there anyway
Glycol Pumps Tasks in Refrigeration System
The glycol circulation pump ensures the operation and performance of this entire system. If it is chosen incorrectly, then there may be problems with the functioning of the cooler, and the ideal mechanism for delivering chilled beer will not work:
- the beer on the taps will be at a different temperature than you and your visitors would like
- filling trunk lines speed will be slow
- there will be various problems with beer foam
Therefore, the selection of a cooler and pump power is a very important process. Before purchasing a particular model, it is better to consult with specialists. Beverage Craft’s online store offers a selection of all kinds of glycol pump models, at least one of which is sure to fit your needs. Consult with the online store specialists, and they will tell you whether a particular model of glycol pump will be optimal for your case, or if it is better to select another one.
Types of Glycol Pumps in Beverage Craft
The Beverage Craft online store specializes in beer equipment, which can be in demand both at the points of beer commercial production and sale, and for home needs. Glycol pumps and motors are one of the top sellers. This beer cooling system appeared not so long ago. However, it immediately became widespread due to its effectiveness and attractive appearance. You can find the following models of glycol pumps on the Beverage Craft website:
- Pump and Motor Assembly for 45, 75, and 100 GPH. GPH is an indicator of how many gallons of beer per hour are cooled by this glycol transfer pump
- Vertical agitator pumps: a special pump for non-standard voltage that does not require shutdown and can work around the clock
- Rotary vane pump for 45, 75, and 100 GPH: the glycol circulation pump has a brass body and is attached with special clamps
How to Choose a Glycol Pump for a Beer Line
In order not to make a mistake with the selection of glycol pumps and not to waste your money, consider the following indicators when choosing glycol pumps and motors:
- The length of the main line, i.e. the distance between the beer kegs stored in the cold room and the bottling tower. This length should not exceed that for which the pump you have selected is designed. The recommended length of the line for a particular pump is indicated on the package and is expressed in feet
- Decide how many types of beer you are going to offer visitors. If this figure is more than 8, then you need two supply and return lines for the glycol-water mixture. This means that a twice as powerful pump is required for the same length of the line.
- How many bars will serve beer from one storage. The branching system also reduces the efficiency of the pump, and therefore, with two or three bar counters in different places, it is necessary to pick a more powerful pump, even if bar counters are located close to each other.
Is One Pump Enough to Serve Beer?
In most cases, one pump can handle all tasks. However, there are exceptions in which two glycol pumps must be purchased:
- If you are going to offer numerous types of beer, and at the same time your pub has a significant number of customers. Since in such a situation the load on the operation of the chiller will be very high, it may fail at some point. To insure yourself in such a case and reduce the load on the glycol pump system, it is better to have two of them.
- If you have several towers for pouring beer, which are located on different sides of the room. Then it is necessary to breed the main lines and buy two glycol pumps.
To date, the beer cooling system using a water-glycol mixture is the most advanced and efficient. If you choose the right glycol pumps and motors, they will work perfectly and smoothly. Visit Beverage Craft to consult with experts and find the best model for your pub.
