Caribbean

PRODUCT DESCRIPTION
The Caribbean models of Grunert refrigeration are designed for those yachts that utilize the power available from their main engine. Typically, all on board energy requirements are condensed into one or two engine run times per 24 hour period.

These units come standard with a cupronickel raw water condenser for improved efficiency and lower operating pressure (unlike other Grunert systems, air cooling is not an option). Add the Grunert Passage maker to the Caribbean system for optimum flexibility for those times when you want to maintain box temperatures and the boat is unattended (or the vessel is hauled). For design assistance, contact you local Dealer or the Customer Support Team at Marine Air Systems.

The compressor components for this system must be installed near or on the main engine with all necessary components nearby.

Caribbean units meet or exceed applicable U.S. Coast Guard regulations, CE Directives and general Air Conditioning and Refrigeration Industry (ARI) standards.

 
FEATURES ---------------
Modular Concept
  • Components can be remote mounted.
  • Receiver, drier pressure switch and valves are on one convenient pallet.
High Quality Components
  • Rebuildable compressor, including valve plates and shaft seals, for long life.
  • Zinc chromate primer protection against corrosion - for all chassis components.
Remote Junction Box (optional)
  • Enclosed box protects components and provides for convenient connections.
  • Low voltage (12 volt) controls provide an extra margin of safety.
Environmental Considerations
  • All systems have base valves with service ports for evacuation and leak checking the system and a receiver for refrigerant storage.
  • Utilizes 'ozone friendly' refrigerant 409A.
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 Caribbean
When choosing the Caribbean primary consideration should be given to calculated BTU loads and available power supply. Any special requirements (number of boxes and/or controls, refrigerant line lengths, wiring sizes, etc.) should be determined prior to installation. prevent refrigerant leaks (due to vibration or loosening of suction side connections due to frost). This compound should be applied sparingly to the male threads of the fitting, and great care must be taken to prevent contact with the flare seat. Flare connections must be adequately tightened - usually as tight as possible, with the exception of 1/4” lines which can be crushed if the flare is over-tightened. All associated mechanical components (solenoid valves, check valves and expansion valves), must be located and secured properly.
