Description
Counterflow Cooler Pro 5.2 m – wort chiller with four TC34mm connections from Brewtools
Counterflow cooler from Brewtools, designed for the Pro series of brewing systems. The cooler is 5.2 metres long and made of electropolished stainless steel (SS304). It has four 34 mm Tri-Clamp connections, two for wort and two for cooling water, so you can fit hose barbs or other fittings as needed. The inner tube has a large diameter (14.3 mm) to restrict the flow as little as possible.
How to use it
The cooler is designed to be used in a loop. The wort is pumped from the kettle, through the cooler and back into the kettle via the dip tube. This creates a whirlpool that collects hops and proteins (trub) in the centre of the tank, so less trub is transferred to the fermenter. When the return temperature reaches your pitching temperature, change the flow direction after the cooler so the wort goes to the fermenter.
- Circulate boiling wort through the cooler before cooling starts, so the inner tube is sanitised.
- Switch off the heating elements before cooling starts.
- Run the pump at full power at first, and slow it down towards the end so the trub can settle.
- Connect the cooling water so it flows in the opposite direction to the wort.
The cooler is not designed for single-pass cooling straight to the fermenter. The large inner tube gives little resistance for the whirlpool, but makes a single pass slower and uses more water.
Performance in Brewtools' own test
Brewtools tested the cooler with 50 litres of boiling wort to be cooled to 20 °C. The cooling water was 9 °C at 19 litres per minute.
| Method | Time | Cooling water |
|---|---|---|
| Whole tank cooled in a loop, then transfer | 19 min | 361 litres |
| Loop until return temperature is 20 °C, then transfer | 16.5 min | 315 litres |
| Single pass straight to the fermenter | 26 min | 500 litres |

FAQ about the Brewtools Counterflow Cooler Pro
How long does it take to cool 50 litres of wort?
In Brewtools' test it took 16.5 minutes from boiling wort to 20 °C in the fermenter, with 9 °C cooling water at 19 litres per minute.
Can I cool straight to the fermenter in a single pass?
You can, but the cooler is not designed for it. In the test a single pass took 26 minutes and 500 litres of water, compared with 16.5 minutes and 315 litres when the wort is circulated first.
Are clamps and hose barbs included?
No. Clamps, gaskets and hose barbs are sold separately.
Why should the cooling water flow the opposite way?
When the cooling water flows opposite to the wort, the hottest wort meets the warmest water and the coldest wort meets the coldest water. This gives the best cooling.
