Wine Cellar Refrigeration Systems – Dual Air Quiet Cooling Units (DQ Series)

The Dual-Air Quiet (DQ Series) wine cellar refrigeration systems are cooling units designed to provide refrigerated air to 55-65 °F. DQ evaporators return air at the bottom and supply two-way air discharge 10-12 feet in both directions at a medium velocity airflow. This design promotes fantastic circulation in long and narrow display cases.

Large Wine Cabinet &Cellar Cooler Series High Performance Quiet Design

These units are the perfect solution for large wine cabinets and walk-in wine cellars. DQ evaporators are available in standard capacities from 1,800 to 4,600 BTU per hour. Contractors use them with an R134a refrigerant.

Wine Cooling Unit Features

  • The air defrosting coil does not require an additional heater.
  • Fan blades engineer for very low noise.
  • Staggered high-performance coils with copper tubing expanded mechanically into aluminum fins.
  • Housing constructed of insulated rust-proof aluminum.
  • The permanently lubricated motor is fully thermally protected.
  • The automatic expansion valve (standard) ensures constant coil temperature to promote “Humidity Balance.”
  • Pump-down solenoid valve (standard) protects compressor in the event of leaks.

DQ Cooling System Typical Installation

  • Keep line sets as short as possible.
  • An excessive number of turns will cause refrigerant flow problems. This action could cause early compressor failure. We recommend suction line accumulators. They’re required if working lower than the standard 55-65° operating range from the wine cellar.
  • The drain line must always flow downhill to drain or pump.
  • A pump controls the system 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. Add 3 oz. oil for every 10′ over 35′.
