ONAM CW-30M Wine Cellar Cooling Systems

Product image shows AA configuration. The ONAM CW-30M wine cellar cooling systems are placed outside the cellar having its supply and return air ducted to the cellar itself. Therefore, only the two vents are visible within the wine cellar achieving a clean look. The CW-30M does not require outside ventilation.

What is required?  Power supply, water supply and condensate drain/built-in pump. A remote electronic thermostat with digital display is included.

Wine cellar cooling capacity - Approx. 4000 BTU (Net Cooling Capacity with cellar temp 55f & 60% humidity rated air flow of 400 cfm.)

17" D x 22.5" W x 24.5" H with Maximum Cubic Footage: 2000 cubic feet.

Although the cooling units are rated for various size rooms, the thermal load may require a larger sized cooling unit.  Thermal load may be affected by glass in the cellar, room positioning or other factors.  Please let a Rosehill Wine Cellar rep make some suggestions for you if needed. 

ONAM wine cellar cooling systems are self contained and easy to install. 

ONAM offers three different models, depending on the exact location of the unit. CW30M is located outside of the wine cellar and the CW30 and CW30W are located inside the cellar. Each of the different cooling units are ultra quiet, free from vibration free and easy to hide. The main benefit of the ONAM cooling units are that they do not exhaust heat into the air but instead heat generated in the cooling process is transferred to water that is then run into the drain. Reliable cooling units for cellars up to 2000 cubic feet.

ONAM Water Cooled Wine Cooling Systems Feature:

These units are designed for residential and commercial applications and easily installed. Requires only a dedicated 110V power supply, a water supply and a drain. The water consumption required when cooling (with a supply of 60F water) is approximately ¼ gallon (1 L) a minute. All ONAM products are designed with the best available components and with the following standard features:

• Powerful: Designed for cellars up to 2000 cubic feet.
• Refrigerant fittings easy accessing for servicing.
• Fan: Maintenance free, squirrel cage fan. (ONAM CW-30M & ONAM CW-30W)
• Evaporator: industrial tube with special dip-coated to resist pitting.
• Stainless steel thermal expansion valve Automatically regulating the refrigerant, while optimizing humidity. 
• Embossed aluminum casing; double walled construction.
• Insulation for quiet and efficient operation.
• Condensate pump included.
• Pressure activated water valve: water flow is automatically regulated for water conservation.
• Condenser is Cupro-nickel coaxial, designed to resist failure from a chlorinated water supply.
• Removable panel -  for easy service.
• Hermetic (vibration isolating) compressor.
• High & low pressure safety valve turns off unit if pressure exceeds limits.
• Safety high temperature controller switches the unit off if the compressor begins to operate at higher than normal temperatures.
• 6' plug in power cord; not hard wired
• R134a - refrigerant.
• Remote electronic thermostatic control for accurate temperature control. Also Equipped with OFF/ON switch (seems obvious, but other manufacturers do not provide this basic control).

• Water line kit included - To assist with plumbing installation, the ONAM water-line kit includes three 4' stainless steel flexible pipes (3/8"comp. x 3/8"comp.).  High Temperature water inlet option also included for environments where inlet temperature may be as high as 95°F. 

   

• All units will be shipped with evaporator coils having the new Electrofin coating – a seven step process involving dipping each coil into five different baths, rinsing and having the coating baked on.  We are sure this will only add to the durability of this component.
• All units will be shipped with Little Giant’s “Next Generation” VCMX Condensate pumps, offering more robustness and a higher head capability.  All pumps will be equipped with a safety switch - should the pump reservoir fill up beyond a certain point, the unit will shut off.  This feature should eliminate the chances of leaks due to condensate pump failures.

Warranty:

The ONAM water-cooled system is warranted free of manufacturing defects, both as to workmanship and materials for the period of two years from purchase date. Field labor is not included.

If your ONAM unit is giving you some problems, please try these trouble shooting tips: 

1. Press the reset buttons on the front of the cooling unit. There is a little cut-out on the metal housing and one switch goes sideways and the other goes up and down. If this was the issue, the unit turns on right away. 

2. Next thing to check is the batteries in the thermostat. There is a small screw to loosen on the bottom of the thermostat, and then it slides up and off. Two double A batteries could need replacing.
