Compact systems for cooling the wort and storage of heat water in BREWORX MODULO modular breweries

The plate heat exchanger is a part of each brewhouse BREWORX MODULO. It provides cooling down of the wort at the end of the brewing process to target temperature of about 20-25 ° C. This is a ideal temperature for starting the fermentation with yeast of upper fermenting.

For the production of on bottom fermented beer it is necessary to cool the temperature of the wort to 6-10 ° C. Therefore, it is necessary to install another brewery equipment for the second stage of wort cooling. In minibreweries BREWORX MODULO the unit WCU (Water Cooling Unit) or the combined water treatment unit WCU / HWT (Water Cooling Unit / Hot Water Tank) are used for this purpose..

1. Modulo WCU (Wort cooling and aeration units with the cold water tank)

– Compact independent units for cooling and aeration the wort with the cold water tank

The WCU  is a compact mobile unit, containing everything to cooling down the wort from temperature of about 20 ° C to a temperature of 6-10 ° C. This temperature is needed for the wort fermentation in the production of bottom-fermented beers. This group includes virtually all types of beer that are common in the Czech Republic – for example, light lager of Pilsner type.

The WCU unit contains :

1) Insulated tank for storage of sufficient volume of ice water.

2) Cooling unit with that provides the cooling water in a cold water tank to a temperature of about 1 ° C from the initial temperature of about 15 ° C within 10 up to 20 hours.

3) Plate heat exchanger, ensuring effective transfer of the cold from ice water into wort.

4) Pump for the necessary flow of ice-water through the plate heat exchanger.

5) Valves and flanges for connection of hoses or stainless steel pipes.

6) Stainless steel frame with wheels or adjustable feet for easy handling with the unit and safe positioning on uneven ground.

Heat recovery using the WCU unit

The implementation of the WCU unit (without hot water tank) into a brewery does not allow recovery of heat produced during wort cooling – the received hot water is discharged into the waste drain, or it is collected into some other vessel – for example into tanks of the wort brew machine.
A limited volume of tanks of a brewhouse allows to save about 40% received hot water. WCU equipped with water tanks of volume 2 – 3 times higher than volume of tanks of the brewhouse machine ensures saving up to 95% hot water energy.

We offer these WCU compact wort cooling and aeration units :

2. Compact WCUHWT units (Wort cooling and aeration units with the cold and hot water tanks)

– the wort cooling units with integrated the heat management system

Mobile independent compact equipment for wort cooling and aeration with the recovery of heat water obtained from waste heat in cooling the wort.

Special module, which integrates the unit for cooling of the wort and the hot water tank on a shared frame with the wheels and adjustable legs. Hot water that we receive from cooling of the wort in the first stage of cooling (in the plate heat exchanger integrated in the brewhouse) is collected in a stainless steel insulated water tank and is ready for use everytime. Most often brewers use the hot water for preparation the next batch of wort, but also when washing and sanitizing other equipment in the brewery. This recuperation of waste heat from wort cooling contributes to substantial savings in production costs.

The WCU-HWT unit contains :

1) Insulated tank for storage sufficient volume of ice water.

2) Insulated tank for storage sufficient volume of hot water.

3) Cooling unit with integrated condenser, which provides cooling in a cold water tank to a temperature of about 1 ° C from the initial temperature of about 15 ° C within 10-20 hours.

4) Plate heat exchanger, ensuring effective transfer of the cold from ice water into wort.

5) Pump for the necessary flow of ice-water through the plate heat exchanger.

6) Pump for creating a pressure in the hot water pipes when using the stored hot water.

7) Valves and flanges for connection of hoses or stainless steel pipes.

8) Stainless steel frame with wheels or adjustable feet for easy handling with the unit and safe positioning on uneven ground.

9) Optionally, the unit can be equipped with electric heating elemets, standardly water is heated in a wort boiling tank in the brewhouse machine.

Heat recovery and utilization of hot water with the WCU-HWT unit

The WCU-HWT unit in the brewery without hot water tank allows recovery to 95% of the heat , produced during wort cooling – resulting hot water is collected in full volume in the tank for hot water. Hot water will be used for the next cycle of subsequent wort boiling, or for washing and sanitizing of brewhouse, tanks and other equipment in the brewery.
