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.

BDXP Systems

The BDxp is has approximately 30% more capacity than the standard BD.   The BDxp should be used in larger refrigerator and freezer applications. The BDxp has an AEO (Adaptive Energy Optimizing) feature. This feature senses the amount of cooling needed and adjusts compressor speed accordingly.   The BDxp may be fitted with a speed control in order to manage power draw. Air cooling is standard; optional air and water cooling is available. Housing size and weight are identical to the BD.

Air Cooled Installation

Ducted air cooling creates the highest efficiency and allows installation in confined areas such as a sail locker, or under a cabinet or seat. The ducting eliminates re-circulation of the cooling air. The air temperature increase is minimal (2° to 3° F.). Air flow can be reversed.

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.
