Energy-Efficient Commercial Refrigerators – Save on Costs

Drop In/ Penthouse Units

Penthouse Refrigeration System – Penthouse Refrigeration Systems are like Standard Top Mount Systems except they do not have an evaporator coil sticking down inside the walk-in. The air inside the walk-in is drawn up through the evaporator coil located with the condensing unit on top of the walk-in to be cooled. A licensed refrigeration technician will be needed to install the refrigeration system. These systems sometimes seem higher in upfront cost but when all things are considered including the fact that they are factory assembled and don’t take up space in the walk-in it is less expensive in the long run.

A penthouse unit is a self-contained system including a condensing unit (discharges the heat outside the box) and the evaporator (absorbs heat when warmer air is passed through, thereby cooling the inside of the unit), which is positioned in a square cutout of one of the roof sections. The air inside the walk-in is drawn up through the evaporator coil located with the condensing unit on top of the walk-in to be cooled. If space is important, a penthouse unit is the most suitable. A custom refrigeration system consists of an evaporator mounted on the ceiling inside of the box and the condensing unit mounted either on top of the walk-in, or in some cases outside on the roof of the building if it is preferable to pump the heat right out of the building.
