The Sea Frost BD Direct Evaporator System is an advanced design that will operate on 12- or 24- volt D.C. power. It is perfect for well insulated refrigerator boxes. The system consists of two components — the compressor, which is remotely located, and the stainless steel cold plate. The two components are connected by pre-charged copper lines attached at the plate. The rugged, half-inch thick polished stainless steel cold plate can be mounted on a shelf, wall or ceiling and offers the highest resistance to damage and corrosion. Optional ice-making trays are available for wall-mounted installations.

BD systems are factory pre-charged and require no special tools for installation. Popular Danfoss® hermetic compressors are used in both the BD and BDxp. These electronically-controlled, variable speed compressors feature state of the art efficiency. BD compressors are totally enclosed with a brushless D.C. fan and efficient, oversized copper and aluminum finned condenser. Ducted air cooling creates the highest efficiency and allows for installation in confined locations.

Sea Frost’s BD is well-suited for boats with adequate battery banks and charging equipment. Thermostatic operation maintains the cold plate at even temperatures. The thin direct evaporator cold plate requires minimal box space. Dockside, the system operates through the boat’s battery charger.

Options include custom plate sizes, custom line lengths, 2-plate freezer systems, freezer bin, remote thermostat, electronic thermostat with speed control, air and water cooling and ice-making tray kits.

All BD systems feature ducted air cooling. The four-inch round intake vent is ducted to the cabin to allow the compressor to draw in ambient temperature air. This air is then forced through the compressor box to cool the electronics and pass through the oversized air cooled condenser. Exhausted air exits through the back side of the cabinet ensuring efficient performance even in tropical climates.
