Beer cooler

Our beer cooler cools the beer to temperatures of -1 to -2 °C with the help of a cooling medium, usually glycol. This takes place in a single-stage plate heat exchanger.

The process is used in the brewing industry to cool the beer for the cold storage phase and therefore ensure optimum temperature control during fermentation. The beer cooler is also used before filtration in order be able to carry it out at the lowest possible temperatures.

Advantages and functions

Constant cooling of the beer to below 0 °C
No freezing of beer due to bypass circulation of glycol
Few armatures are needed when using glycol
Quick achievement of cooling temperature
Wide capacity range of 40 – 100 % of nominal capacity
Hygienic design, full CIP capability
Easy operation, low maintenance effort, long service life
Fully automatic operation with standard PLC and touch panel
Optional integration in process control system and remote maintenance
Individually dimensioned and designed for each specific application
Equipment and components according to customer specification
Compact tubular-frame system (skid mounted)

Technical Description

The beer to be cooled flows through a single-stage plate heat exchanger in countercurrent to the refrigerant glycol. The beer is cooled to a constant temperature of -1 or -2 °C in a very short time. The flow rate of the beer is optionally controlled by a frequency-controlled pump.

If glycol with very low temperatures is used as refrigerant, the system is equipped with bypass control. This prevents freezing of the beer by recirculating warm glycol.

The unit can be controlled by a local PLC with a touch panel or by a process control system.
Designed for high hygienic standards, all common cleaning agents in the brewing and beverage industry can be used for CIP cleaning.
