Bingshan BSET has successfully delivered a customized batch of marine refrigeration compressor units for a major fishing fleet in Southeast Asia.
This advanced brine cooling system is specifically engineered to provide sustainable, low-temperature seawater for pelagic fishing vessels.
By optimizing the catch preservation process, the system significantly extends the vessels' at-sea endurance and backward journey times, ensuring that fish products maintain premium freshness upon arrival at the homeport.
Technical Profile: High-Efficiency Marine Refrigeration Process
To withstand the harsh corrosive environment of tropical oceans and guarantee continuous operation, Bingshan’s technical team designed a highly stable direct expansion (DX) liquid supply system.
The technical specification highlights include:
1. Eco-Friendly & Reliable Refrigerants: Compatible with Freon alternatives including R22, R404a, and R507 to meet diverse global maritime environmental compliance standards.
2. Heavy-Duty Working Conditions: Specially rated for reliable performance under challenging tropical ambient conditions, with design rating points at -5°C (Evaporating) / +35°C (Condensing).
3. Premium Marine-Grade Equipment Configuration: Each customized system integrating a heavy-duty marine refrigeration compressor unit, anti-corrosive brine condenser (seawater condenser), liquid receiver, gas-liquid separator, and high-efficiency dry evaporator.

Operation Profile: Three-Stage Seawater Brine Cooling Mode
Unlike conventional chilling methods, this project utilizes a smart three-stage brine cooling sequence to maximize thermal efficiency and product shelf-life:
1. Pre-Chilling on Outward Journey: Utilizing the ship's outward transit time, the system pre-chills the onboard seawater from an ambient +25°C down to +0°C before reaching the fishing grounds. This proactive cooling minimizes the thermal shock when the system goes under full load.
2. Ice-Water Mixture Formation: Before the catch is loaded into the fish-rooms, the pre-chilled 0°C seawater is pumped into individual holds and mixed with a small amount of crushed ice. This forms a perfect ice-water slurry that wraps around the fish instantly, rapidly lowering their core temperature and halting enzymatic degradation.
3. Freshness Maintenance on Backward Journey: During the long backward journey to the port, the system continuously circulates the cooling seawater to absorb residual heat from the fish body and water volume. The seawater inlet/outlet temperature is strictly maintained between +5°C and 0°C, ensuring the catch remains in a premium, fresh-frozen state for extended return voyages.
