Marine Refrigeration Unit
CB has years of deep expertise in deep-sea refrigeration technology. As an industry-leading marine refrigeration system provider, our MSC-XX-FN-M Series Marine Refrigeration Unit, has integrated design to aim to premier position in the high-end marine refrigeration market.
Unit is optimized for extreme sea conditions including high-salinity corrosion and heavy rolling/pitching, and has a compact footprint and rapid installation. It adopts eco-friendly NH3 refrigerant, the system supports fully automatic, high-efficiency operation across multiple operating conditions. It can be used Widely on large process trawlers and purse seiners with flexible integration with terminal equipment such as shelf quick freezers, RSW/low-temperature brine heat exchanger, and air coolers—demonstrating superior system integration capabilities in deep-sea applications.

Product Features
Supports 10%–100% stepless capacity regulation and variable volume ratio (Vi) adjustment, cooperated with a high-precision VFD control to achieve precise matching between energy output and actual load. Utilizes a three-stage horizontal oil separator to strictly control discharge oil carrying ratio below 6 PPM, eliminating thermal-resistance oil film formation on terminal heat exchanger surfaces right from the source. Forced Oil Feed System: A dedicated oil pump at the bottom of oil separator to has forced supply with multi-point precise oil injection line, equipped with a dedicated oil temperature control valve. Oil cooler can be configured with two independent design options based on operational needs: seawater cooling or refrigerant cooling. Fully complies with marine classification society rules and standards.
Product Advantages
Multi-Condition Adaptability: Comprehensively matches diverse process requirements from coastal fishing to ocean processing, including catch pre-cooling, quick freezing, and cold storage. Eco-Friendly & Green: Utilizes NH3 natural environmentally friendly refrigerant, meeting low-carbon and environmental protection requirements. Reliable Oil Return Operation: Incorporates multi-stage oil separation along with marine-grade oil return structures and system design, ensuring oil return and long-term durability. Minimalist Operation & Maintenance: Automated control system minimizes relying on highly experienced crew members, reducing manual operation and maintenance costs. Exceptional Structural Stability: Features a robust unit structure that delivers absolute mechanical reliability under high vibration, heavy salt corrosion, and extreme environments.
