Marine Combi System

This multiple water-cooled condensing unit has been treated and coated specifically for use in the marine environment, so you can enjoy years of trouble free service. The neat, self-contained package is ready to install in boats from 45 to 100 feet (14-30m). For larger boats, multiple units can be used.

General Specifications:

• Three models to choose from:
  1. DC: 24-28V DC, 135A using 3.5kW brushless motor
  2. AC: 110-240V AC, 50-60Hz using 400V DC brushless motor
  3. Hydraulic: 10kW precision built hydraulic motor;
• Combi Touch Screen Colour Display drives and allows for monitoring of all compressor clutches, raw water coolant volumes, desalination and deck wash pressures, all internal temperature and pressure settings and air conditioning capacity control. One Combi Display can control up to 20 Combi units with a single 3mm, 75 Ohm input/output co-axial cable;
• Firewall prevents damage to Combi electronic circuits from accidental high voltage inputs. Incorporates mini switchboard providing protection for all Combi-driven pumps and circuits, (approx 10 individual fuses);
• Optional Emergency Manual Override in case of electronic failure, allowing manual switch-over, bypassing all electronic systems;
• Three independent compressors can be dedicated to any combination of air conditioning and/or refrigeration;

Refrigeration Specifications:

• Refrigeration power of up to 47,000 BTU (14kW), using internal compressor;
• Additional refrigeration power of up to 47,000 BTU using external compressor mounted on propulsion engines or genset.

Air Conditioning Specifications:

• Capacity controlled air conditioning power of up to 40,000 BTU (12kW), using internal compressor;
• Temperature and pressure sensors for monitoring air conditioning and refrigeration systems;
• Air volume control of air conditioning handlers;
• A range of compact, speed controlled, 24V DC operated evaporators are available, from 8,000 - 40,000 BTU. Evaporators can be run by gas or chillers. Alternatively, evaporators can be used for heating by circulating the vessel's hot water system or genset/propulsion engine coolant.

Desalination/High Pressure Deck Wash Specifications:

• High pressure pump delivers 13 L/min, (3.5 US gpm), to 105 bar (1,500 psi), ideal for desalination and other high pressure saltwater needs, such as High Pressure Deck Wash (with desired function selectable via switch). Pump output pressure is adjustable via Combi Display;
• Desalination option produces 180-200 L/hr, (53 gph) or 4,800 L/day, (1,270 gpd);
• High Pressure Deck Wash allows you to switch between salt and fresh water.
