There are basically two cooling methods for beer dispensing systems: wet cooling devices and dry cooling devices. Both variants are so-called flow coolers. Here is the difference:
Dry cooling devices :
Dry cooling devices work with a solid cooling medium, a cooling block, which is cooled down to the desired temperature.
In special stainless steel cooling coils, the beer is passed through this cooled block when it is tapped.
These devices are compact, lightweight and ready for use quickly.
Wet cooling devices :
Wet coolers use liquid coolant that directly cools the beer as it flows through special cooling coils.
These devices are efficient and are well suited for professional use in the catering industry.
The integrated accompanying cooling cools the beer until it reaches the tap
