JoinTech G20 Glycol Chiller – 2 Pumps

This glycol chiller allows you to precisely control fermentation temperature, even on large volumes. Thanks to its two independent pumps, it can manage two fermenters in parallel or stabilise a single fermenter up to 200 litres. Its 16.42 L reservoir and R600a compressor provide reliable cooling power for demanding brews.

To ensure optimal performance, this unit requires a 100 mm clearance around all ventilation areas. Regular dust removal from the radiator is also essential to maintain system efficiency. Ideally, it is used with a 30% glycol/water mixture, achieving a freezing point of around –8 °C.

Why choose this product?

• Precise fermentation control thanks to two independent pumps.

Rolling Beers Tips

• Use a 30% glycol/water mix to optimise cooling performance.
• Place the chiller in a ventilated area to improve heat dissipation.
• Rinse the glycol circuit once a year to maintain performance.
• For cold crashing, pre‑cool the bath 2 hours before starting the temperature drop.

Product FAQ

• Can it cool two fermenters at the same time? Yes, thanks to the two independent pumps.
• Which glycol should I use? 30% propylene glycol is recommended.
• Is it compatible with all fermenters? Yes, as long as they are under 200 L. You will need to adapt the hose connection to your fermenter.
• Can it be used for wort chilling? Yes, BUT only if the temperature is below 50 °C.
