Custom-made 15 Ton Triple Chiller Assembly (back)

45 Ton Triple Chiller System
(Three 15 Ton Chiller Assembly)

From 6 ton up to 150 ton available. Ready for installation. Vertical configuration is available.
Completely assembled in the factory. Can be taken apart completely, and then reassembled and installed onboard a yacht.



Custom-made 15 Ton Triple Chiller Assembly (front)

45 Ton Triple Chiller System
(Three 15 Ton Chiller Assembly)

The above modular Ocean Breeze chiller is designed for retrofit or new yacht installation, from small yachts to mega yachts. Typical lead time is 6 weeks from the time our draftsman measures the existing equipment aboard the yacht to the completion of the installation. Drawings in SolidWorks format from our engineering department are then submitted for approval along with complete electrical system design. The completed modular chillers are then assembled and tested in the factory, disassembled prior to delivery, and then reassembled aboard the yacht. Average installation by a two-man team takes about 10-14 days.

    Do not use CPVC (chlorinated polyvinyl chloride) piping with a chiller system which uses polyolester (POE) oil. Refrigerant leaks in the evaporator/heat exchanger may release polyolester (POE) oil and refrigerant into the chilled water piping. Polyolester (POE) oil and refrigerants break down into acidic compounds (including the sludge-like heptanoic and isononanoic acids) when exposed to water and are therefore incompatible with CPVC (chlorinated polyvinyl chloride) pipes. Exposure to these acidic contaminates may result in pipe softening, degradation, cracking, and failure, especially in areas where the piping is under stress. Polyvinyl ether (PVE) oil is compatible and will not degrade CPVC (chlorinated polyvinyl chloride) piping. It is recommended to drain and flush out any and all chilled water piping when upgrading from a polyolester (POE) oil or mineral oil system to a system which uses polyvinyl ether (PVE) oil.



    Installation Notes

  • Min Seawater Condenser Flow: 2.4 GPM per 12,000 BTU (1 Ton)*

  • Max Seawater Condenser Flow: 3 GPM per 12,000 BTU (1 Ton)*

  • Piping for pump intake and discharge must be at least 4 inches of bronze or cupro-nickel pipes.

  • Max Circulation Water Flow: 3 GPM per 12,000 BTU (1 Ton)

  • Fan Coil can be controlled by motorized valve.

  • 2-way or 3-way or fan cycling

  • All thermostatically controlled.

  • All chillers must be bonded and grounded.

  • Pencil zinc must be installed on condenser manifold discharge.

  • Minimum 30% glycol or 30% antifreeze for chilled water circulation. Do not use automotive antifreeze. Marine antifreeze only.

  • Chilled water piping must not be made from CPVC if the system uses POE oil.

  • Chilled water piping insulation: ½" insulation minimum,
    ¾" insulation recommended.

  • Gate valves are recommended for flow adjustment. If ball valves are used, the handle should be removed after the flow adjustments have been made.

  • Valves used for the seawater piping must be bronze. Valves for the chilled water piping may be either bronze or brass.

  • Make-up water system is optional.

  • Seawater in and out connections can be changed to either side of the condenser coil depending on the application.


    • *Pump selection is very important. Insufficient water flow can cause the condenser coil to reach higher temperatures, accelerate corrosion of the condenser coil, decrease compressor efficiency, and decrease the overall lifespan of the compressor.

    Adequate Water Flow vs. Inadequate Water Flow

    Inadequate water flow will fail to flood the coil and does not have enough pressure to push out air. It will also be unable to cool the condenser and fail to carry away heat from the unit. Failing to flood the condenser will leave air pockets with a turbulent water surface which aerates the water with air bubbles. If the pressure is too low and below the vapor pressure of water, cavitation inception will occur and bubbles will form from dissolved air and water vapor. Air bubbles are caused by cavitation and can cause mechanical erosion from shockwaves from the imploding bubbles. The shockwaves can erode the protective cuprous oxide layer on the cupro-nickel. Without the protective cuprous oxide layer, harmful chemicals such as hydrogen sulfide gas, dissolved in water contaminated by sewage and bacteria, will leave the copper vulnerable to corrosion. Insufficient water flow can cause the condenser coil to reach higher temperatures which can accelerate corrosion reactions.

    1 ½ HP, 109 GPM Seawater Pump

    Piping for pump intake and discharge must be at least 4 inches of bronze or cupro-nickel pipes.
    Heat, high-pressure, and harmonic vibrations can cause PVC to crack and fail.

    2.4 GPM × 15 tons = 36 (Min.) to 45 (Max.) GPM Flow Rate per Chiller
    72 (Min.) to 90 (Max.) GPM Total Flow Rate for Both Chillers

    *GPM testing can be done with an electronic or mechanical guage, or manually with a 5 gallon bucket and a stopwatch.

    *Seawater-in is on the side of the refrigeration liquid line (never the discharge side) and is labeled as "Water In."
    It is critical to follow the labels. Condenser coils can be ordered and manufactured so that the seawater-in can be on either the left or right side.
