Manufacturing the ONAM CW-30 Series - the original water-cooled refrigeration system specifically designed for wine cellars - since 1986. Unit does not require air venting or gravity drain - use with domestic water (internal water regulation ensures water conservation) or closed loop systems (condenser, chilled, or geothermal loops) with entering water temperatures as high as 95° F. Easy plug-and-play installation - a refrigeration technician and regular maintenance is not required. System can be installed in a space adjacent to the wine cellar, or can be built-into millwork. Standard features: Internal condensate pump, heavy gauge aluminum construction, SS fasteners, robust German engineered evaporator fan and compressor, high and low pressure safety switches, high and low pressure refrigerant access ports, SS thermal expansion valve, cupro-nickel condenser, and dip coated evaporator (industrial tube thickness).
