Wine Cellar Refrigeration Systems – Low Profile Quiet Cooling Units (LPQ Series)

The Low Profile Quiet (LPQ) wine cellar refrigeration systems are cooling units designed to provide refrigerated air quietly and dependably. LPQ Systems are an excellent choice for quiet, long-term storage. They require very low maintenance. These ceiling-mounted wine refrigeration units are excellent for vaulted rooms. The LPQ unit supplies refrigerated air behind the coil, down the wall, and brings return air in the angled front, promoting circulation.

LPQ Single & TE Cooling System – Typical Installation

  • Keep line sets as short as possible.
  • An excessive number of turns will cause refrigerant flow problems. This could cause early compressor failure. Suction line accumulators are recommended. Required if working lower than the normal 55-65° operating range from the wine cellar.
  • 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′.
