Temperature control
Chiller
Municipal or tap water is generally the lowest-cost way to remove most of the heat from freshly boiled wort. If your water is not cold enough to reach pitching temperature—or you want to conserve water—first chill as far as practical with tap water through the fermentor jacket or a plate chiller, then finish with a BREWHA brewery chiller.
For Small through Large systems, switching around 30°C / 90°F is typical. Larger systems can often switch around 20°C / 70°F. The first warm-water runnings can be recovered for cleaning or the next hot-water requirement.
If the final temperature drop is too large for the chiller alone—as may happen with 1.5 BBL and larger systems—or tap water is above 10°C / 50°F, use a cold liquor tank to finish the job. On larger commercial systems, some brewers also circulate wort from the fermentor through a plate chiller and back in a closed loop to reduce knockdown time.
Where to purchase
- BREWHA 3,000 and 6,500 BTU brewery chillers are available with optional jacket hoses and a fitted utility cart. The 6,500 BTU model includes two circulation pumps and is recommended for tanks 1.5 BBL and larger.
- BREWHA offers one-stage and two-stage counter-current plate chillers. A one-stage unit works when cooling water is below 10°C / 50°F; a two-stage unit is useful where tap water can perform most—but not all—of the chilling.
- A dual-purpose hot/cold liquor tank can store the chilled water needed for the final cooling stage.
