The BMB20-C integrates a direct-expansion aluminum alloy evaporator, an industrial-grade condensing unit, and an integrated ice storage bin within one corrosion-resistant container. The container is thermally insulated and ventilated according to marine standards, ensuring safe operation in ambient temperatures from -20°C to 50°C. All internal piping and wiring are factory-fitted and tested, reducing site commissioning to a single-day process requiring only external power, water, and drain connections.

Inside the container, water is distributed into vertical direct cooling molds where refrigerant circulates through the plate jackets to form transparent ice from the inside out. Once blocks reach the target thickness, a digital controller initiates a hot-gas defrost cycle that releases the blocks into an inbuilt harvest tray. Melt water and impurities are automatically drained outside the container. A fail-safe hydronic balancing manifold ensures equal refrigerant flow to all plates, regardless of container tilt on uneven ground.

The containerized design eliminates civil works for a dedicated ice room. The system features a semi-hermetic compressor, a marine-grade water-cooled shell-and-tube condenser with cupronickel tubes (optional), and a touchscreen PLC with remote cellular monitoring. A vibration-isolated frame protects all components during truck or ship transport. Power supply is 380V/50Hz/3P, easily reconfigured to 440V/60Hz; the container includes its own weatherproof electrical room with lockable access. Full compliance with CE and ISO 668/1496 shipping standards simplifies cross-border deployment.

Ocean fishing/port aquatic wholesale

Large block ice melts slowly, maintaining low temperatures in fishing holds or trading pools for 3~5 days, suitable for centralized ice use on ships or docks.

Food processing workshop environmental cooling

Place large ice blocks in the workshop during summer to continuously cool using high latent heat, with no wind chill, suitable for meat processing plants and dairy factories.

Concrete dam pouring temperature control

Crush large ice blocks into ice shavings during mixing; large blocks are easy to transport and store, with high direct cooling efficiency to meet the ice demand for engineering volumes.

Storage of vegetables/fruits pre-cooling

Block ice combined with cold fans is used for rapid pre-cooling in the field to prevent respiratory heat accumulation.
