PEM nut inserts and numerous stainless steel rivets
All sheet metal components are laser cut with aircraft/military quality tolerances in the ten-thousandths of an inch range as depicted here with the skeleton of an air-cooled chiller. Note the PEM nut inserts and numerous stainless steel rivets that result in a very rigid, strong and exacting structure.

Built at our Sturat Florida Plant.
All Flagship Marine condensers are hand-crafted from start to finish at our Stuart factory location to our exacting specifications

Still Built with Pride in the USA
with Only Domestic Alloys.
No Cheap Imports.

Flagship Marine's chillers are the most rugged, commercial/military quality chilled water systems available! When downtime can equal lost dollars, the durable and dependable Flagship Marine units are money in the bank.
To make the very best in chillers we put the very best materials in the hands of skilled technicians. Our chillers are built to last decades. Made in the USA Since 1995
• All stainless components are 316 marine grade stainless steel!
• Evaporator housings, drain pans, electrical boxes etc.
are 5005 marine grade aluminum!
Copper Nickel socolets
Flagship Marine takes no shortcuts
with quality and design!


   All condenser tube to manifold connections are made with precision machined 90/10 CuNi (Copper Nickel) socolets that are TIG welded to the schedule 80 90/10 CuNi nipple with a monel alloy and brazed to the condenser tubes to ensure many years of trouble free service.

   This configuration meets all MilSpec and ABYC requirements. Naked connections aren't nearly as durable and fail to meet those standards.
   For your convenience all manifolds are fitted with reducing couplers and a 3/4" drain plugs for winterizing.

Expansion Valve
EXPANSION VALVES VS. CAPILLARY TUBES


All Flagship Marine equipment incorporates expansion valves which adjust the modulation of the refrigerant to match the conditions of sea water, humidity and ambient temperature. This maximizes performance by preventing excessive or inadequate refrigerant head pressures, resulting in more cooling and extended component life!
This is why all new HVAC equipment must now use expansion valves instead of the capillary tubes you may still have in your home air conditioner.
We don't "cut corners" - these cost us about $75-175 each vs a $3.00 cap tube, and on the larger units we use "balanced port" rather than the standard expansion valves which automatically adjust to the amount of refrigerant flowing rather than being a fixed flow and out of balance.

Capillary tubes cannot adjust the refrigerant modulation which is fixed by the physical length of the tube. Like a broken clock that is right only twice a day, capillary tubes either over-modulate or under-modulate the refrigerant as the sea water temperatures vary. As an extreme example, if you are in upper Mississippi when the water is 40° and the air is 95° the modulation will be excessive and the head pressure much too low. Expansion valves adjust the modulation according to the conditions.
No Capillary Tubes
Dry Drain Pan
Flagship Marine Exclusive: Dry Drain Pan
No more mold and mildew starting in your drain pan!
We now manufacture sloped aluminum drain pans that are dry so the condensate water doesn't have a chance to grow mold and mildew.
sheet metal components
All sheet metal components are laser cut with aircraft/military quality tolerances in the ten-thousandths of an inch range as depicted here with the skeleton of an air-cooled chiller. Note the PEM nut inserts and numerous stainless steel rivets that result in a very rigid, strong and exacting structure.
Variable Frequency Drives
If your vessel is wired single phase or you have marginally sized generators, or if you want to almost completely eliminate voltage fluctuation when compressors start, we can install Variable Frequency Drives (VFDs) in our equipment. 
The VFD reduces the start up inrush and will greatly reduce any brown out, generator lag or flickering in your TV when the compressors start. 
The typical inrush (millisecond start up amperage) is about 5-7 times the running amps, however with a VFD the compressor frequency slowly ramps up to the 60 HZ speed so the inrush is typically about 1.3 times the running amps.  You can also manually program in lower or higher frequencies as well to accomplish running on lower amps or more output at higher amps if you need to, but of course you will lose or gain proportional performance by doing so.
Flagship Marine strives to provide the most simple, trouble free and durable equipment available, and frequency drives are not in keeping with the KISS principal that guides our component selection and design, however there are applications that warrant these excellent products.
Diagnostic Monitor with ICM Modules
Flagship's Exclusive Diagnostic Monitors Use
Time Tested "Over the Counter" ICM Modules
No Printed Circuits
With Flagship there are no expensive proprietary printed circuit boards.
No highly trained technician needed, typically a voltmeter and a
screwdriver is all that is needed to make most repairs!
All Flagship Chillers have a low voltage control module with clearly labeled LEDs advising the end user specifically what has tripped the chiller, be it high or low refrigerant pressure, freeze control protection as well as low chilled water flow. Diagnostic Monitor Panle
Programable Digital Control

Our new digital control is programmable or you can override the programs and manually control the temperature.

In addition to a host of features it has a back-lit screen for programming even in the dark.

ANY four wire battery-operated control will operate ANY Flagship Marine Unit

Personalize Your Thermostat

We STRONGLY suggest a strainer and anti freeze (Polypropylene that is non toxic) be installed on the return chilled water to the chiller.

Our chillers have many freeze control safety devices - refrigerant low pressure cut off, freeze protection cut off as well as a low chilled water flow shut off. However there is one malady that will defy all of 
these measures - spot freezing.

If debris in the chilled water loop plugs even a small section of the evaporator, there will be a dead spot of stagnant water at this location causing a cold spot that is prone to freezing and evaporator rupture, causing total system failure and an expensive repair.  The low pressure can be normal and the freeze control will not be tripped 
because it's only a small section that freezes.

In a typical system the return chilled water is 54°F and the exiting water is 46°F. However the refrigerant is about 20°F - well below freezing, so if you have a small section of stagnant water you can have a complete system failure by rupturing the evaporator at that small section.

The ONLY protection is an anti freeze solution, and the best preventative measure is installing an 16 - 20 mesh strainer before the evaporator.

Brazed Plate Heat Exchanger Cleaning Recommendations

We recommend that you clean the heat exchanger by reverse flushing it with a mild organic acid solution. In other words have the acid solution enter the heat exchanger through what is normally the water outlet. The flow rate for the flushing should be greater than the normal operating flow rate of the heat exchanger (2 x if possible).

When using a solution other than water, always use it according to instructions and check with the supplier that it is compatible with the materials in the heat exchanger. The units are constructed of AISI 316L Stainless Steel with AISI 304L connections. The units are brazed with pure copper.

Once the cleaning operation has been completed, you may want to also run a solution (1 – 2 %) of either sodium hydroxide (NaOH) or sodium bicarbonate (NaHCO3) through the heat exchanger. This solution will neutralize any residual acid that may have remained after flushing the heat exchanger with water. The heat exchanger should also be thoroughly flushed with water after using the neutralizing solution.

Cleaning Solution:
9 % Phosphoric Acid
35 % Citric Acid
1 % Inhibitors
55 % Water

A cleaning solution with approximately the same constituents should be available at any refrigeration or industrial supply house (try Grainger). Care should be taken that the cleaning compound will not negatively affect either Copper or stainless steel. If you have any questions or require further information please feel free to contact us.
