Solutions - Armatura w instalacjach RSW

Background

Today's fishing industry grows more competitive with every catch. Distances become greater. Quality demands increase. To not only survive, but to maximize profits, it is essential to utilize the best technology and finest equipment available. Whether it is a small boat or a large fishing vessel, refrigeration is essential for delivering top-quality products and receiving premium prices from today's demanding seafood buyers. RSW, or refrigerated sea water is a relatively new technology to the commercial fishing fleet.

In  simple  terms,  a  RSW-system  functions  as  follows  :  Seawater  is  recirculated  by  pump through the tanks (therefore product) and the chilling system. The seawater is chilled by the refrigeration machinery before it enters the tanks through a set of perforated plates or similar distribution devices. The chilled seawater passes upwards through the tank and layers of fish, thus keeping the fish semi-floating (in suspense) and at the same time cooling it.

The water circulating system is arranged as such that the flow can be reversed by the operating certain valves in the main water distribution manifold.
