Scraped-surface cooler POLAR

Ideal for the refrigeration of musts, juices, and wine, up to the freezing point, the Spadoni POLAR scraped body coolers (C-48) are characterized not only by high efficiency, but also by a modern line and the very best components.

The Scraped-surface cooler POLAR consists of three sections: evaporation, scraping and condensation.

The evaporator-constructed of AISI 304 stainless steel, with external polyurethane foam insulation-is the part of the system where the expansion of the refrigerant gas (R404A or R22) and the consequent absorption of heat from the liquid to be cooled takes place.

Function of the scraper-which is driven by a gear motor and rotates inside the evaporator cylinder-is to mix the refrigerant and increase heat exchange. It consists of a shaft, equipped with scraper blades, which keep the heat exchange surface clean by removing brine and sludge. This makes this machine particularly suitable for cooling liquids with a high percentage of suspended solids or a high ratio of impurities.

Finally, the condensing unit, which has the task of expelling the heat absorbed by the liquid together with that generated by the compression work, is operated by air (a finned battery composed of copper tubes with aluminum fins) and is positioned at the inside the machine, with a consequent notable advantage in terms of compactness and transportability.

Spadoni’s POLAR scraped-body chillers are produced in one-piece versions, on wheels, or structured on a fixed frame, depending on size.
