Wine Cellar Refrigeration Systems – Rack Mounted Cooling Units (RM Series)

The Rack Mounted (RM Series) wine cellar refrigeration systems are optimized cooling units, built to deliver refrigerated air sufficient for medium-high temperature locations – custom wine cellars, wine tasting rooms, and large cabinets. RM series evaporators mount horizontally, often within the wine racking. These units have several access panels to forward or redirect the supply and return vents. Do you need to place your cooling unit between ceiling joists, in a soffit, or on a wall? The Rack Mounted series may be a perfect choice. These are the most versatile and therefore our most popular cooling products.

RM evaporators are offered in standard capacities from 2,600 to 6,600 BTU per hour and are used with R134a refrigerant.

All cooling units manufactured by US Cellar Systems are Split Wine Cellar Refrigeration Systems.

Wine Cellar Cooling Unit Features

  • The staggered coils include mechanically expanded copper tubing in aluminum fins. These features provide a particularly high performance.
  • Aluminum housing is insulated and rust-proof
  • The permanently lubricated motor is thermally protected
  • The automatic expansion valve (as standard) ensures a constant coil temperature which promotes “Humidity Balance.”
  • Pump-down solenoid valve (as standard) protects compressor in the event of leaks.
  • The need for additional wiring to the thermostat is eliminated by the use of pre-installed valves.
  • Manufacturer pressure tested to ensure quality.
  • Factory wired for simple field installation.
  • ETL certified.

RM Wine Cellar Refrigeration Systems – Typical Installation Instructions

  • Keep line sets as short as possible.
  • An excessive number of turns will cause refrigerant flow problems. This action could cause early compressor failure. Suction line accumulators are a recommended addition to this evaporator. They are required if working lower than the normal 55-65° operating range from the wine cellar.
  • The drain line must always flow downhill to drain or pump.
  • The system is controlled by a pump-down control system. There is no control wiring between the thermostat and condensing unit.
  • The line connections at Fan Coil and Condensing Unit may not be the same as the required line sizes.
  • Standard line sets should be 50′ or less. Extended runs may require larger line sizes and 3oz oil must be added for every 10′ over 35′.
