To satisfy unique refrigeration demands of offshore operations featuring heavy continuous load, non-stop running and high-precision temperature regulation, as well as core process standards for differentiated temperature zone storage and constant-temperature fresh-keeping of fishery products, CB provides a dedicated refrigeration system for this vessel, consisting of:
* 4 sets of NH₃/CaCl₂ secondary refrigerant cooling screw compressor units,
* 24 sets of floor-standing air coolers with auxiliary equipment.
* A professional floor grating air circulation system is also equipped to fully optimize the terminal airflow circulation system inside holds, ensuring evenly distributed and stable temperatures throughout the entire fish hold, and perfectly meeting storage & transportation requirements of simultaneous multi-temperature zone operation and long-term fresh preservation of fishery goods.

CB NH₃/CaCl₂ secondary refrigerant system effectively solves the drawbacks of traditional marine refrigeration system, thoroughly resolving core pain points such as insufficient temperature control accuracy, single available temperature zone, high risk of ammonia leakage, which easily lead to fish cargo loss and threaten the safety of onboard operators.

After commissioning and operation, the system enables independent and synchronous operation of multiple high & low temperature zones to match fresh-keeping demands of various types of fishery products, while drastically cutting energy consumption for onboard cold chain logistics and overall operational costs. Compliant with the low-carbon, energy-saving, safe and high-efficiency development philosophy of pelagic fisheries, the system remarkably elevates the safety, stability and intelligence level of the vessel’s cold chain operations.
