How to choose cooler: Classic Cooler or Flowing Cooler?

In distillation, the cooler is almost as important as the still itself. It is the place where vapor meets cold water and where aromatic vapors are transformed into the final distillate. If you are wondering which cooler suits you better, the classic cooler or the flowing cooler, we will explain it simply below.

The classic cooler is made of galvanized steel. Vapor from the still passes through a copper coil immersed in a vessel filled with cold water, and this water is periodically replaced or topped up in order to remain cold. The drawback of the classic cooler is that, due to its larger volume, it consumes more water, and when working with larger quantities, it can operate more slowly compared to flow-through coolers. The quality of the obtained distillate is the same, but more effort is required to regulate the temperature of the distillate. The advantage of this cooler lies in user habits, and habits are difficult to change.

On the other hand, the flowing cooler is made of stainless steel. It works by continuously allowing fresh cold water to enter the cooler, while the heated water is discharged through a drainage hose. Vapor passes through a tube system surrounded by cold water at the appropriate temperature. The water flow is adjusted using the installed valve, the optimal cooler temperature is 40–60 degrees, and the temperature of the outgoing distillate should certainly also be monitored. This allows the distillate to be cooled more efficiently and continuously, which is especially important with larger stills.

The flowing cooler cools evenly, enables precise control of the cooling temperature, requires a constant and regulated water supply, and has a capacity of 30 liters, providing significant water savings.
