Polar Mate

PRODUCT DESCRIPTION
The Polar Mate , from Grunert, provides 12 or 24 VDC marine refrigeration in a compact system. Components are specifically designed to fit in restricted areas aboard any vessel. Three models feature air, water, and air/water condensers for maximum versatility. Air cooled units are used when thru-hull fittings are not desired or when the vessel is hauled. Water-cooled units provide increased efficiencies, and air/water units provide extended efficiencies for proper operation in high ambient temperatures. Evaporator assemblies are offered in both small and large capacities with custom configured assemblies upon request.

The Polar Mate is ideal for small boxes or day sailing applications. For design assistance, contact your local Dealer or the Customer Support Team at Marine Air Systems.

Polar Mate condensing units can be installed in any convenient location and are unaffected by vibration or moisture. All units meet or exceed applicable ABYC and U.S. Coast Guard regulations, CE Directives and general Air Conditioning and Refrigeration Industry.

FEATURES ---------------
Complete Kit
  • Unit can be shelf or bulkhead mounted.
  • Two sizes of evaporators can be configured for custom applications.
  • Horizontal evaporators are supplied with a door assembly and a horizontal ice cube tray.
  • Vertical evaporators are supplied with an extruded aluminum vertical ice cube tray.
  • 15’ refrigeration line set with “quick disconnect” fittings provided with each system.
High Quality Components
  • Hermetically sealed compressor for quiet, efficient operation.
  • All chassis components are painted with marine grade polyurethane to guard against corrosion.
  • Water cooled condenser constructed of spiral fused cupronickel encased in a copper shell provides maximum heat transfer and high corrosion resistance to see water flow.
Environmental Considerations
  • All units have quick disconnect fittings and are pre-charged with refrigerant for ease of installation.
  • Utilizes “ozone friendly” refrigerant 134A.
Quality Assurance
  • Each unit is assembled with a charge of nitrogen to ensure that scale does not form during soldering.
  • Every unit is leak checked, test run and shipped pre-charged with refrigerant.
  • Charge Guard® protection provides sealed access ports to ensure system integrity during handling and installation.

Installation Guidelines for Polar Mate
When choosing the proper model Polar Mate primary consideration should be given to calculated BTU loads and available power supply. Any special requirements (box capacity, air condenser exhaust, wiring sizes, etc.) should be determined prior to installation. (shut off valve) must be installed directly on the speed scoop outlet. A sea water strainer is mandatory between the sea cock and pump. The sea water system should be installed with an upward incline from the speed scoop & sea cock, through the strainer, to the inlet of the pump and then up to the inlet of the condenser coil. Use only reinforced marine grade hose. All hose connections shall use double/reversed stainless steel hose clamps. Seal all thru-hull fittings with a marine sealant designed for underwater use.
