PRODUCT DESCRIPTION
The Mariner series of holdover refrigeration systems is available from
1/4 HP capacities, for use with 12,24, or 32 volt DC power supplies, and has
been proven to be the ideal system for seafaring vessels with or without on-board
AC power. Its unique design allows for automatic operation when either the alternator
or the battery charger is energized. An electrical interlock prevents accidental
battery drain.
These units come standard with a cupronickel seawater condenser for improved
efficiency and lower operating pressure. The extensive Mariner series
can efficiently cool a number of different box sizes and configurations. For
maximum versatility, add an optional air cooled condenser to provide uninterrupted
service when the vessel is hauled or unattended.
Condensing units can be installed in any convenient location and are unaffected
by vibration or moisture.
the Mariner series units meet or excced applicable ABYC and U.S.Coast
Guard regulations, CE Directives, and general Air Conditioning and Refrigeration
Industry (ARI) standards.
FEATURES
- Unique compact base fits any application.
- Water cooled and air/water cooled units avaiable.
High Quality Components
- Rebuildable compressor, including valve plates and shaft seals for extending life.
- Replaceable brushes on all DC motors.
- Continous duty cycle rating on DC motors.
Remote Electrical Box
- Completely enclosed box protects all components.
- On board low voltage(DC) circuit provides safe operation of controls.
Environmental Considerations
- Utilizes "ozone friendly" refrigerant R-409A.
- All units have base valves with service ports for evacuation, leak checking and refrigerant containment.
Quality Assurance
- Each unit is hermetically sealed using nitrogen to ensure a contaminate-free
circuit.
- Every unit is leak checked, test run and shipped pre-charged with refrigerant.
- Charge Gaurd® protection provides sealed process ports to ensure system
integrity during handling and installation.

- BTU ratings are the average rate of heat extraction from either
26 °F, 0 °F,-9°F or -18 °F solution holdover plates, and are not the capacity of the compressor
or condensing unit.
- 32 volt DC availalbe upon request.
- For wire size, ampacity, etc., refer ro ABYC Standards, Section E-9(DC Voltage).
