Let's walk through how this beverage cooling setup works:

First, the cold source starts with the chiller-inside it, there's a shell-and-tube evaporator. This evaporator's main job is to cool water by a steady 5-6°C; once the water's chilled, it gets stored in a 3,000-liter cold water tank (the tank just keeps a consistent supply of cold water on hand, so there's no lull in cooling).

Next, a pump moves that cold water from the tank over to the plate heat exchanger. This is where the beverage actually cools down: the cold water and the beverage flow through the exchanger side by side (no mixing, just heat transfer), and the beverage's temperature drops by about 1-2°C (gentle enough to keep its flavor intact).

A quick functional note on the heat exchanger: it's made of stainless steel (non-negotiable for gear that touches beverages, since it's food-safe) and it's detachable. This isn't a "feature" to sell-it's a practical detail: the detachable design lets you take the plates apart to clean every surface, which is key for keeping beverage equipment sanitary.
