RDI Rack Systems
Rack Systems are designed to provide optimum
performance and efficiency. All systems utilize R-404A
refrigerant for environmental protection and unregulated
distribution.
This catalog offers a wide range of standard model
compressors from 1/2HP through 15HP. Systems are
listed with BTU/HR capacity at different ambrinks and SST.
All systems are mounted on a rugged structural steel
frame. Air-cooled models are available for indoor
installation or with outdoor weather housing fabricated
of stainless steel, G-90 galvanized or unpainted paint grip
steel. All systems are available for indoor installation with
water-cooled
condensers.

TYPICAL WATER COOLED REFRIGERATION SYSTEMS ON 3 UNIT RACK

Outdoor enclosures provide durable and attractive protection to condensing units from the elements. The air louvers
on the enclosure feature one-piece construction, die-formed blades, folded corners and smooth seams. Louvers are
easily removable, without tools, to access control panels and normal service points. The entire enclosure may be
removed for major maintenance of the equipment. One-half to three-horsepower units require one enclosure rack
space while five-horsepower units fill two horizontal spaces.
