Quality construction and proven reliability for storing your vintages since 1986.  MAN System (previously known as ONAM or Onam cellar cooling in the wine trade) is made with embossed heavy gauge aluminum, stainless steel fasteners and designed to commercial standards.  This elite cellar cooling system boasts an evaporator with industrial tube thickness, dip-coated to resist pitting (7-step ElectroFin process), robust German engineered hermetic compressor with internal/external vibration isolators, oversized cupro-nickel coaxial condenser for efficient heat transfer and superior resistance to chlorinated water supplies.  For the wine cellar compressor, we have a German engineered and constructed scroll cage blower which is quiet and maintenance free.  The water valve is pressure activated for automatic water flow regulation (ensures high efficiency and water conservation).  The stainless steel expansion valve automatically regulates refrigerant flow to maximize efficiency while minimizing dehumidification!  A very important feature in climate control for your wine collection.

MAN Systems are CSA certified to Canadian and US standards.  They have extensive QC testing including 24-hour pressure testing.  It is environmentally friendly with R134a refrigerant and has a high / low pressure safety control to disable unit (preventing compressor failure) if operating

pressures fall below or exceed preset limits.  The internal, self resetting temperature switch disables the unit if the compressor cavity exceeds normal operating temperature. 

MAN’s thoughtful design features include:  an Internal condensate pump to eliminate the need for a gravity drain,  a safety switch that prevents equipment operation if pump fails, non-marking rubber isolators minimize vibration and sound transfer, wired remote digital thermostat for accurate wine cellar temperature control complete with on/off switch, refrigerant filter dryer protects the refrigerant system keeping it operating optimally.

MAN Systems are quiet and compact, yet powerful enough to cool a properly insulated space (R20) as large as 2,000 cubic ft.  It can be concealed within millwork which is a bonus for cooling efficiencies in the wine storage room.  It can be used with closed loop condenser water, chilled water or geothermal systems with water temperatures as high as 95°F.  This is an excellent feature in wine rooms for penthouses or condos, where water is not allowed and ducting to the exterior is not an option.  The Man or Onam cellar system can also be used with domestic cold water (while flow is internally regulated to ensure water conservation), provided this is allowable in your district.

The unit is serviceable with removable panels provide, has refrigerant sight glass for visual

diagnostics of system operation, and refrigerant access fittings on high and low sides of the compressor.  It is easy to install as well.  MAN Cellar Systems are a self contained refrigeration system where a refrigeration technician is not required.  Electricians are not required to hard wire

power to equipment.  The unit plugs into a standard (120 VAC) receptacle (15amp dedicated circuit)!
