A modular refrigeration system having an evaporator, a condenser, a compressor, and expansion device fluidly connected by a plurality of conduits. The modular refrigeration system includes an integral base plate to which the evaporator, condenser, expansion device, and compressor are mounted. A compressor mount is formed in the base plate and includes at least one integrally formed stud extending from the base plate. The compressor has at least one mounting flange in which the stud is received. A fastener is affixed to the stud to secure the compressor to the base plate. A drain pan is formed in the base plate beneath the compressor to collect condensate. A drain basin is located beneath the evaporator and is fluidly connected to the drain pan via a trough. Condensate from the evaporator drains to the drain pan where it is evaporated.
