Marine Refrigeration & Chilling the Catch
125 Rton Freon DX Chiller
100 Rton NH3 Condensers
200 Rton NH3 Condenser
When we started back in the 1990’s, there were no brine chillers and the refrigeration took place only in the fish wells, which was highly inefficient. Fish backbone temperature reduction took days, whereas now it takes hours. Ti-Marine developed both flooded and DX chillers and these technologies significantly improved fish quality through faster freezing of the catch.
In order to handle these increased chilling loads, the Ti-Marine line of Ammonia and Freon condensers was continually improved. Enhancements to the tube surface, larger tube diameters, stacking two units and water boxes made from Titanium added to the value of a Titanium condensers.
Our marine refrigeration systems see the broadest use because cooling the catch is priority number one. Large or small, all fishing vessels need to chill the catch as fast as possible. This is best accomplished with lots of seawater / brine circulating around the fish. Brine flows in Titanium tubes are typically between 1.5 to 2.0 times higher than what copper and brass can handle. And all the tubes in a Ti-Marine unit are individually seal welded into the tube sheet, so erosion is not a concern. The Ti-Marine line of refrigeration heat exchangers runs from 20 Rtons up to 500 Rtons, in both Ammonia and Freon.
This advantage applies from the smallest RSW chiller to the largest refrigeration condenser. It’s not unusual for an ‘over-under’ combination of an ammonia condenser/brine chiller to be stacked in the space previously occupied just by the original condenser.
