In the wort cooler, the hot wort is cooled down after boiling to the pitching temperature of 5 to 15°C. This is done in a two-stage plate heat exchanger, first cooled by brewing water and then by glycol.
The process is used in the brewing industry and is essential before the yeast is added to the wort, as it can only ferment at low temperatures. The closed pipe system and the hygienic design prevent the contamination with beer-damaging microorganisms.
After cooling, the wort is aerated. We also have the right system for this in our product portfolio.

The hot wort flows at almost 100 °C into a two-stage plate heat exchanger. In the first stage, it is precooled with brewing water in countercurrent flow. The wort heats the brewing water to 80 to 85 °C, which is then used for the next brew. In this way, the heat is returned to the brewing process instead of being lost.
In the second stage, the wort is cooled with glycol to the required final temperature for pitching.
All incoming and outgoing media are monitored by temperature sensors. The outlet temperature of the wort is regulated by a frequency-controlled supply pump in the glycol circuit. The wort flow is also regulated by a frequency-controlled pump.
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. The upstream valve combination allows the heat exchanger to be cleaned backwards.
