Top Rated Self-Contained Refrigeration Systems

Self contained refrigeration systems are also called "drop-in" and fit into a pre-cut hole in the walk-in cooler/freezer they are intended for.  Self-contained refrigeration systems come in both top and side mount models: the completeness of the sealed system is its main characteristic.

Self-contained refrigeration systems are often referred to as “drop-in” units.  These systems are used for walk-in freezers and coolers such as those found in restaurants.  The reason they are called self-contained is because the condensing unit, blower coil and controls are all connected and sealed together.  Self-contained refrigeration systems fit into a pre-cut hole in the freezer or cooler.  These systems can be either top-mounted or side-mounted.


When purchasing either a top or side-mounted unit the buyer must be aware that some shelf space will be sacrificed.  The top-mounted system effectively drops the ceiling down and may lead to the loss of top-shelf storage space and head room in the cooler. Purchasing a system with low profile coils may eliminate that issue. 


Alternately, side-mounted systems take up space on the side wall where shelving could be.  A second consideration for side mounted self contained refrigeration systems is the condensation hose must be connected to a drain.
