Hydrocooler by water shower

[magic360 id=”5″]

Maxwell hydrocoolers have a perfect design, which achieves a very high performance and low energy consumption. These hydrocoolers are perfect for post-harvest cooling as the residence time, equipment and cooling specifications are designed to meet your needs.

What is it for?

The Hydrocooler quickly reduces the core temperature of fresh produce, prolonging shelf life and preserving taste and appearance.

How does it work?

The system consists of a flooded stainless steel heat exchanger on which ice accumulates.

A shower system sprays water onto the pallets and returns to the pool containing the ice water and heat exchanger. With this system the water does not rise above 0,5ºC.

Details
