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.

 Water Cooled Option

The water cooling option, added to the BD air and BDXP air cooled systems, incorporates a copper-nickel tube-in-tube condenser. A remote pump, elected by a switch on the cabinet, operates with the compressor and fan. Water cooling should be used in engine room or other confined installations. This type of condenser utilizes the scrubbing effect of water and is far more efficient than static water cooling.

Water cooling is standard on the BDXPX systems.

Stainless Steel Freezer Bin

For a small freezer within a refrigerator, the stainless steel freezer bin is ideal. Two walls of the Freezer Bin are double sided direct evaporator cold plates which freeze the bin on the inside, creating a small freezer, and refrigerate the cabinet.

The bin should be mounted high in the box, either vertically or horizontally, and operates best in a relatively small, well insulated cabinet. The standard built-in thermostat regulates the compressor to maintain constant temperatures. Other options include a remote thermostat, Electronic Thermostat Thermometer with speed control, stainless steel door, starboard bin lid and ice making tray kit. Custom widths are also available up to 12 inches.
