RDI Systems: Matched Refrigeration for the Walk-In Box

A new walk-in cooler goes up behind a deli on a Monday. By Friday it has to hold 38 degrees through lunch rushes, door openings and a hot afternoon on the roof. The panels and the door are the easy part. What decides whether that box works is the pair of machines that move the heat: an evaporator inside, pulling warmth out of the air, and a condensing unit outside, dumping it into the atmosphere. RDI Systems builds both halves of that pair, sized to work together.

Chapter 1

A refrigeration line built around operating cost

RDI Systems presents its equipment around two ideas: lower energy use and lower cost of ownership over the life of the system. Its evaporator range covers low height, low velocity, low profile, medium profile, heavy duty and warehouse coolers and freezers, roughly 3,600 to 28,000 BTU/h in the published range, aimed at supermarkets, beverage storage, refrigerated warehouses and industrial rooms. Its outdoor condensing units run from fractional horsepower to large multi-horsepower sizes, with hermetic or scroll compressors and an integral liquid subcooling circuit that adds a few degrees of subcooling before the refrigerant reaches the expansion valve. RDI equipment is listed as made in the USA.

The Lineup

What RDI Systems builds today

The RDI Systems equipment HVAC365 carries falls into two groups:

Low profile unit coolers: medium temp models with air defrost and low temp models with electric defrost, built with EC fan motors in two- and three-fan cabinets.
Medium temp condensing units: scroll units for walk-in coolers, including pre-charged models on R-448A.
Low temp condensing units: freezer-duty units in single- and three-phase configurations.

See every evaporator style under unit coolers and evaporators.

Questions

Frequently asked questions about RDI Systems

What does RDI Systems make?

RDI Systems makes commercial refrigeration equipment for walk-in coolers and freezers: unit coolers and evaporators for inside the box, and air-cooled condensing units for outside.

What is the difference between medium temp and low temp equipment?

Medium temp equipment holds coolers at roughly refrigerator temperatures, while low temp equipment is built for freezers. Low temp unit coolers usually use electric defrost because the coil runs below freezing.

What does a pre-charged condensing unit mean?

A pre-charged condensing unit ships from the factory with refrigerant already in it, which simplifies installation when it is paired with a matched evaporator and line set.

Why do RDI unit coolers use EC motors?

EC, or electronically commutated, fan motors use less electricity and give off less heat than older shaded-pole and PSC motors, which lowers the load on the refrigeration system itself.
