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.

Temporary cold storage in disaster areas/war zones

Rapid deployment and production of block ice to provide basic cold chain environment for medicine, vaccines and perishable food, no need for a fixed factory building.

Remote mining areas/oilfield living areas

Ice is provided for workers' canteens and food preservation. The brine mode can produce transparent ice for direct drinking water cooling (with good viewing effect).

Large outdoor activities (music festivals, sports events)

On-site ice production meets diversified requirements such as catering stalls, first aid stations, and ice sculpture exhibitions.

Tropical islands/seasonal fishing grounds

No need to build a permanent ice factory; the container moves with the fishing vessel during the operation cycle to reduce logistics costs.
