Everything You Need to Know About Beer Coolers

A beer cooler is a device or container designed to keep beer or other beverages cool. There are different types of beer coolers, including portable coolers, often used for picnics or barbecues, and electric refrigerators specifically designed for storing beer. Some beer coolers come with special features, such as temperature control, single-tap or dual-tap options, or integrated cooling technology to keep beverages cold for longer periods. They are particularly popular for ensuring the optimal drinking temperature of beer and enhancing the drinking experience. 

How does a beer flow cooler work?

A beer flow cooler is a cooling device that ensures the beer from a keg or tank reaches your glass at the optimal temperature. The beer is pumped through the beer line into the flow cooler. The cooler consists of a closed system that passes the beer through an insulated, single-tap or dual-tap line, lowering the temperature. The core of the cooler is a heat exchanger, which cools the beer by circulating it with a refrigerant. The flow cooler is typically used in conjunction with a beer tap system to dispense beer from the keg. The beer case has a continuous tap capacity of 60 liters per hour. The dimensions depend on different models of dry cooling devices. The dimensions also depend on the appearance of the beer cooler. Beer coolers come in keg form or in the shape of a beer case. 

What is a dry or wet cooler?

The difference between a dry cooler and a wet cooler when tapping beer lies primarily in how the beer is cooled. 

Dry cooler:

Functionality: A dry cooler uses an aluminum or stainless steel block through which the beer flows. This block is heavily cooled by a cooling element, similar to a refrigerator. The beer is cooled as it flows through the block and can be tapped directly.

Usage: Dry coolers are compact and can quickly bring beer to the right temperature. They are ideal for mobile use, events, or places where no permanent installation is possible.

Maintenance: Easier to maintain as no water refills or changes are necessary.

Advantages: Ready to use quickly, no water cooling needed, easier to handle.

Disadvantages: Often somewhat noisier in operation as the cooling system constantly works. It can be more difficult to maintain temperature stability with very high throughput. 

Wet cooler:

Functionality: A wet cooler uses a water chamber that is cooled by a cooling system. The beer runs through coils (usually stainless steel) within this water chamber, cooling it down. The cold water chamber ensures constant cooling of the beer, even with high throughput.

Usage: Wet coolers are ideal for permanent installations in bars, pubs, or at large events where a high amount of beer is tapped continuously.

Maintenance: Requires regular maintenance, especially refilling water and cleaning the system.

Advantages: Very stable in cooling, especially with high throughput, quieter operation.

Disadvantages: Heavier and bulkier than dry coolers, longer preparation time, regular maintenance required.

Conclusion:

Dry coolers are more flexible and better suited for mobile use or smaller events where quick readiness is needed.

Wet coolers, on the other hand, are ideal for permanent use in professional environments where constant and stable beer cooling is required.

Regular cleaning of your flow cooler is essential to maintain the quality of the beer and prolong the life of the device. Some models feature straightforward cleaning procedures, while others require special cleaning agents. Be sure to carefully follow the manufacturer’s cleaning instructions.

Here are some maintenance and cleaning tips:

• Regularly clean the cooler to remove deposits and impurities. Use a suitable cleaning agent and thoroughly rinse the cooler. Instead of being forced to buy a complete cleaning kit for the tap system, we offer individual cleaning kegs.
