FREEZERS
SPILLOVER SYSTEMS

For proper storage of frozen food, holdover plate surface area must be increased over that of the same refrigerated space. A spillover freezer/refrigerator system consists of two holdover plates in one section of the box. The box is divided by an air tight insulated wall. A self contained temperature controlled air damper (thermodamper) is fitted at the bottom of the divider wall. A return air port is fitted in the top of the divider wall. This thermodamper automatically controls the amount of cold air flowing between the freezer and the refrigerator.

SINGLE VALVE
(Series Systems)

In a large cabinet, or if the freezer section is not large enough to fit plates to cool both refrigerator and freezer, a series system will be needed. This system has two plates in the freezer and one plate in the refrigerator. All three plates are piped in series. The refrigerant flows from one valve to the freezer plates and from there to the refrigerator plate.

TWIN VALVE
(Two Zones)

Two zones may be obtained by solenoid switching the refrigerant flow. Two valve units are used, one for the freezer and one for the refrigerator. The freezer, refrigerator or both may be operated. This is used where the freezer is not always needed, where the freezer needs more running time than the refrigerator, or where the cabinets are not adjacent to each other.
