Electric heat vs. Reverse Cycle    How to Size Your Boat    Coleman/RVP Air-Cooled Rooftop AC




Our new design, which has evolved over many years of experience, has resulted in the most rugged, simple, trouble free and compact unit available today. A child can follow the schematic!

No expensive proprietary printed circuit boards, no add on charges for "controllers"- everything is in one modular electric control box and is "over-the-counter"!



HUGE amount of power with a TINY footprint!

This 15 ton (180,000 BTU) chiller with a bulletproof Copeland ZP154 scroll compressor
(155,000BTU air cooled - we DON'T skimp!) is an incredible 19.5" wide x 29" long x 19.6" high!!!!!


Even so, all critical components are readily accessible and our exclusive low voltage
monitor is conveniently mounted on the top of the evaporator.


Electric box not shown and is on 6' leads.


  


This 360,000 BTU dual compressor chiller has an incredible 31" x 52" footprint and is only 39" tall!


The evaporator refrigerant circuit is bufurcated with a single chilled water loop, so you have two completely isolated refrigerant circuits!
The control box has independent RANCO temperature controllers, transformers, circuit breakers and voltage/phase protection, and everything is over the counter!


chiller

This 10 ton extreme-duty chiller has been designed for sea water temperatures of
up to 105°F and is fitted with optional sea water manifolds with 150#
four bolt flanges, chilled water flow switch and refrigerant gauges.



ALL components of our standard-duty,  8 ton unit are easily accessible.



 


What sets Flagship Marine apart from our competition is our belief in the KISS principle (Keep It Simple, Stupid). This has guided our component selection and design emphasis for many years. We brag that even a child can follow our schematics!

Look at this single compressor chiller electric box. All the components are “over the counter” at a fraction of typical costs in our industry. The most expensive item here is less than $53.00!



Flagship Marine incorporates only the highest quality components that are primarily manufactured in the States, and all the production takes place at our factory locations in Stuart, FL.

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!!!



When real estate is in short supply, as it always is, how about ten tons (120,000BTUs) of air cooled chilled water on a 22"x 28" footprint!!!!!!
It is ten feet high, but this is often not a concern.


The outside panel features a six-row copper/copper condenser with six HP of blowers to accommodate the most extreme conditions!

The inside panels are all removable for easy access to everything, and the eye-level, convenient electric box has ALL of the electrical components in it, next to the legendary, over the counter and bulletproof Ranco ETC controller, as well as our exclusive low voltage control center, refrigerant gauges and charging ports.



How about 30 tons of air-cooled chilled water on an incredible 22"x 84" footprint!!!!!!!
Flagship Marine components fit together with aircraft quality precision.

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.

 

WHY FLAGSHIP MARINE UNITS
NEVER
HAVE CONDENSER FAILURES!

The heart of every marine air conditioner is the condenser—the heat sink to the ocean and the only component the corrosive sea water touches is the inside of the inside tube.  Failure of this tube is catastrophic for the entire system. Even extremely corrosive places like the very high salinity of the Red Sea are no problem for Flagship Marine condensers because we use an unusually thick walled 90/10 CuNi (copper nickel) tube with particular annealment, hardness and other characteristics.
We don’t dramatically shorten our condensers to save money by enhancing this tub: knurling or rifling for example. Our tube is “slick walled” with no thin spots that fester these failures.   
Paper thin condenser tubes dissipate heat very quickly so the condenser tube can be short and inexpensive.  We don't cut corners by doing so.  We have full length condensers!  The shorter the condenser, the cheaper it is and the shorter it will last!

Flagship Marine has always prioritized durability and quality over cost savings and we NEVER cut corners. We also don’t skimp on our brazing material—ALL refrigerant lines are brazed with a 15% silver alloy, not the 5% typical of other manufacturers. As a result, Flagship Marine is very proud to have had almost ZERO condenser failures in the last two decades!

CHOOSE FLAGSHIP MARINE FOR CONSISTENT QUALITY AND DURABILITY!




CONDENSER SERVICE TIPS

Every 5-7 years or so, it's good form to chemically clean the inside of the condenser tube with a phosphoric acid solution (such as "Barnacle Buster"), and if in fresh water every couple years with a bleach solution.  In locations with muscle crab infestations more frequent treatments may be necessary.  This will bring the condenser back to a like-new condition.

Over the years the heat transfer will be diminished by a marine growth which will gradually increase the refrigerant pressure and reduce efficiency. Simply circulate the solution through the condenser for a couple hours or so (depending on the dilution), and when you're done a high pressure garden hose will help blast away any stubborn deposits. Muriatic acid will also work but it unnecessarily removes the protective patina and is VERY hard on your lungs and the environment!



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





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.


We manufacture a variety of different sized chilled water holding/storage tanks. Shown are 40 and 80 gallon tanks in 14 gauge stainless steel.

Must be on the low pressure return line, and be sure the pump sucks from the bottom of the tank so eliminating air bubbles is easy. You DON'T want the pump to suck a bubble and cavitate! 

A small expansion tank open to atmospheric pressure should be placed at a high point. 

The holding tank can be at any opportune location, typically in the bilge or engine room immediately before the pump, and is flooded - the expansion tank is plumbed to the top of the holding tank
.

OPTIONAL SEA WATER MANIFOLDS



Also available, for a fraction of the cost, are these Hi-Max PVC manifolds that come with the hose and double stainless steel clamp connections - properly sized for your particular chiller.

Flagship Marine's sea water manifolds are 90/10 CuNi schedule 80 pipe, which is MUCH more durable (about 10x thicker!) than our competitors' tubing. These, in combination with the socolets, meet mil spec requirements and will FAR outlast all others. No sinking or water damage hazard from ruptured hoses or paper thin manifolds at 3AM!
 

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.

Flagship Marine takes no shortcuts with quality and design!

FREQUENCY DRIVES AND DIGITAL SCROLL COMPRESSORS?
      The new frequency drive and digital scroll compressor technology is certainly interesting, and it's very entertaining to watch a scroll compressor spool up and down, but in the marine industry we see no appreciable benefit to warrant the significant complexity and expense to justify incorporating this technology in our equipment.
      Scroll compressors, by their design, ALWAYS start "unloaded", regardless of residual head pressure.  They can restart one second after shutting down effortlessly, unlike a piston or rotary compressor.  The only concern is having enough run time to insure the refrigerant oil returns to the compressor, so it's good form to have a significant temperature differential.
      Flagship Marine strives to provide the most simple, trouble free and durable equipment available, and frequency drives and digital controllers are certainly not in keeping with the KISS principal that guides our component selection and design.  Of course if you do want these compressors we will oblige!
     If saving 3% in electricity over the life of the compressor is important to you, then these new technologies might justify the initial added component expense, and the complexity and ongoing maintenance expenses you will incur over the years.  We will be happy to oblige.

Typical single-evaporator chilled water fan coil features:

  • Precision-engineered 16-gauge anodized aluminum chassis, drain pan and evaporator housing are lightweight and corrosion resistant.

  • Drain pan under evaporator only. This results in a dry chassis and no condensate sloshing.

  • Engineered hat-section reinforcing plate provides exceptional strength and light weight.

  • Incredibly rugged and simple over-the-counter components in electric box – no proprietary, expensive printed circuit boards!

  • Whisper-quiet Dayton split-pole blower motors, absent the humming sounds of variable speed DC motors.





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!

The optional heat can be one of our legendary incoloy clad electric elements in the fan coil (shown), an in line oil fired boiler, an electric element in the chiller, or reverse cycle.

We prefer the electric elements in the fan coils because the entire system is shut down when in the heating season - the only moving part is the blower motor when heat is called for.

We have had tens of thousands of these elements in service for many years - they are extremely safe and basically indestructible.

Flagship Marine keeps it simple which maximizes savings and greatly increases reliability while minimizing costly down time!


With multiple chillers plumbed in parallel our competitors will say you "MUST" turn the water off to chillers that are not running and slow down the chilled water flow accordingly to maintain the temperature differential.  They will sell you all sorts of expensive and complicated, proprietary equipment and controls to accomplish this, such as pump VFDs (Variable Frequency Drives) and control circuit boards.

We disagree - this is completely unnecessary.  If for example one of four chillers is running it's true that the overall temperature differential will be 25% of what it would be if all four chillers were running, however if only one chiller is needed to maintain the desired chilled water temperature what difference does this make?  None.  The one chiller that is running is perfectly happy with it's typical 8-10° temperature differential being mixed with the dormant chillers which will result in about a 2° overall differential - so what?  The loop is still 46°!

We have many years and millions of operating hours of experience with such systems without any of these controls... the air handlers only know what the chilled water loop temperature is - the chiller differential is irrelevant.  If one chiller is needed to maintain the 46° temp only one will be running.  When the load increases the second chiller will kick in to maintain the 46° temperature, as the load increases at high noon the others will kick in as needed.

When someone says you "must" or you "have to"- take it with a grain of salt. They are probably just trying to sell you something expensive or justify their unnecessarily complicated equipment! We truly believe in the KISS principal (Keep It Simple Stupid!). You will not find elaborate and expensive proprietary printed circuit boards and controls with Flagship Marine, saving you a LOT of money and saving you a LOT of down time when these components fail. A Phillips head screwdriver and a voltmeter is typically all you need to fix a Flagship Marine chiller, and the most expensive electrical component is the legendary Ranco ETC controller that is over the counter and about a hundred bucks!

Another good one is "You must control the refrigerant head pressure by modulating the sea water flow through the condenser". No you don't!  We size the pumps for the worst case heat of the summer, so in the winter with cold water the head pressure is a bit low - so what? The compressor is very happy and relaxed with the lower head pressure and amperage!  This is ONLY a problem in very extreme situations such as the northern Mississippi river when the water is 33° and the air is 105°!  Then the head pressure may truly be so low it becomes a problem, but this is very atypical!

Considering a Mini Split System?

This fairly new innovation has one variable speed condensing unit supplying refrigerant to up to eight small remote evaporators.  This can result in a very significant savings to the end user in certain situations, such as a home, by cooling only the rooms that are occupied.

In a marine application it's not typical for air conditioned areas to not be occupied, so these savings are not realized in the marine industry.  However, the many detriments of these systems remain and they can be acute in a marine application.  It's no wonder why no marine HVAC manufacturer makes mini split systems.  If  you do decide to install a residential system on your vessel, you should expect to be replacing the outdoor components quite frequently! Due to the adverse marine environment you might get a couple years out of the condensing unit!

In operation when one of the remote evaporators calls for cooling, the slave board in the remote evaporator sends a signal to the mother board in the condensing unit. This triggers the compressor to ramp up and open the solenoid going to that evaporator to provide refrigerant thus cooling the room.

Every remote evaporator requires its own refrigerant lines connecting it to the condenser.  On a typical vessel you will have hundreds of feet of refrigerant lines, half of which are cold return lines that must be insulated. Each evaporator requires  separate piping and wiring of the power cable, the refrigerant tubing, the suction tubing, and a condensate drain between itself and the condensing unit.  Now imagine all of this buried behind panels, deck heads and cabinetry.   This is reminiscent of the split systems of the past which have fallen out of favor in the marine industry over the years because of the ongoing maintenance and down time due to relentless refrigerant leaks caused by  rotted copper lines and leaking brazed joints that are so hard to locate.

Imagine the difficulty a technician will have trying to sniff out a leak that could be anywhere along these hundreds of feet of refrigerant lines.  At least every 50' (the length of a roll of copper tubing) you have a brazed joint, and these lines are buried in the structure of the moving/flexing vessel.  With a SINGLE leak the ENTIRE system is down!

As proven time and time again there is "no free lunch" with thermodynamics, so the tonnage is the same resulting in no weight or current savings.  The only way to save weight is to use thin sheet metal and other inferior components.  If the load is 12 tons you will need twelve tons of cooling regardless of the type of system - you will NOT be running a mini split system at 25% capacity at high noon with a hundred people on board!  It will be 100%!  A chiller system works the same way so at 10PM your Flagship Marine chiller might be running ten minutes/hour, so the total current consumption will be basically the same with any system.

The condensate is oftentimes problematic because it can be difficult finding a sensible means of running a condensate drain from every remote wet evaporator.  Sometimes it's easier to run dry ducting rather than install wet evaporators.

In conclusion, we believe a chiller system in these applications is much more desirable, and especially with Flagship Marine equipment you will have ZERO expensive/proprietary printed boards that can cost you a small fortune over the years.  Mini splits are the MOST complicated/complex systems electronically. Printed circuit boards and naked copper tubing don't do well on a moving, flexing vessel in a marine environment!

Some advice and common sense about warranties:

As with most contracts, the first and most important thing to read in any warranty is the smallest print... unless it's a "No questions asked" warranty (which they never are). Almost all warranties are only as good as the honor of the company standing behind it.

I know of companies that have literally NEVER performed on their warranty because it is NEVER the fault of the product. "I know this compressor is only two months old, but it obviously failed from low voltage (or high voltage, or a lightening strike, or
it's burned from a lack of cooling water - TAKE YOUR PICK!)".

The most wonderful sounding and comprehensive warranty can be absolutely worthless. In some cases they offer extended warranties for a handsome fee, which are again absolutely worthless with the wrong company - save your money! These are nothing more than a very lucrative alternate profit center!

We do not offer "extended warranties" for a fee and we do stand behind our products!
