Remote System

The condensing unit sits outside the building which allows the heat to be released outside. Remote systems generally cost less for the unit itself. Although installation may cost more. Some parts like pipes, insulation & connectors will be needed. Some remote systems come precharged & preassembled from the factory, while others must be assembled and charged during installation.

Self Contained System

A pro is that the self contained system has the evaporator coil and compressor mounted to the top which is best for installation where space is limited on the side. Comes preassembled. Although, heat is released inside the building, and the coil sits inside the box taking up some shelf space.

Rack System

The size of the refrigeration system, how powerful it is in terms of horsepower, depends on whether it is a refrigerator, freezer, or both. For example, smaller refrigeration units generally have a 1/2 horsepower compressor while freezers have a 1 horsepower compressor for greater cooling power. Larger units will require increasingly more horsepower as the box size increases.
