Description

Flagship Marine FM18RLP (230V Cool & Heat) Low-Profile Marine Air Handler

The Flagship Marine FM18RLP (230V Cool & Heat) deploys a space-saving self-contained framework engineered to supply a powerful 18,000 BTU/h heating and cooling solution directly to localized cabins up to 1,000 cu.ft. The heavy-duty 12.0×21.0x15.0-inch low-profile chassis installs remotely within narrow bulkhead layouts, pumping conditioned air smoothly at 550 CFM through a 6-inch duct connection to prevent hot spots. This dense engineering configuration delivers exceptional thermal regulation on complex international yachts, providing the ultimate choice over a traditional 230v chilled water fan coil alternative layout.

Operational safety on a single-phase 230V 50/60Hz electrical infrastructure is secured by an integrated hermetic rotary compressor pulling a 6.9A cooling current and an 8.3A heating current. The 74 lbs assembly utilizes a rugged stainless steel frame paired with premium cupronickel condenser loops, holding mechanical machinery vibration sound emissions to an absolute minimum while managing a 32A locked rotor startup surge. External seawater loops require a continuous 4.16 GPM pump feed through 5/8-inch pipe links, finishing an optimized build that handles global frequency configurations safely.

Technical Capabilities and Attributes for Flagship Marine FM18RLP (230V Cool & Heat):

  • High performance 18,000 BTU reverse cycle cooling and heating
  • Compact 12.0-inch profile maximizes vertical space clearance in cabins
  • Premium cupronickel condenser loops prevent severe saltwater oxidation damage
  • Heavy duty stainless steel base frame resists machinery room rust
  • Ultra efficient 6.9A nominal cooling running current draw profile
  • Hermetic rotary compressor mechanism minimizes localized cabin vibration sound
  • Standard 5/8-inch seawater inlet and outlet plumbing connections size
  • Universal 230V framework adapts to international yacht generator grids
  • Rigid 74 lbs structural chassis ensures stable bilge mounting
  • Pre charged eco conscious R-410A structural refrigerant loop

Advanced Thermal Exchange Performance

Cupronickel condenser coils provide maximum thermal transfer across all high-temperature seawater circuits by optimizing heat absorption boundaries. The system loop interfaces directly with external staging modules, guaranteeing stable technical operations as a core element of an integrated NMEA 2000 marine HVAC distribution network. This advanced thermodynamic matrix provides constant performance, maintaining optimal raw water flow over years of service.

Comprehensive Manufacturer Coverage and Service Protocols

A comprehensive 5-year limited factory warranty protects all structural parts against defects under standard marine operating protocols. This coverage delivers direct component remediation through authorized dealer channels, ensuring original engineering tolerances are maintained without out-of-pocket material expenses. Vessel owners enjoy peace of mind knowing mechanical and electronic infrastructure elements are fully secured.

Vessel Layout and Application Fit

Vessels measuring 36-45ft are perfectly sized for this compact low-profile marine climate control configuration. It is uniquely engineered to serve interior cabin spaces up to 1,000 cu.ft that require a minimal 4.5 kW auxiliary generator overhead. Seamless hardware optimization balances continuous moisture extraction, letting operators maximize layout space while reducing internal equipment strain.

Flagship FM18RLP 230V AC FAQ

What are the electrical requirements for FM18RLP?

Flagship FM18RLP operates safely on a 230V power connection. This heavy-duty single-phase configuration draws low operational current during active reverse-cycle heating cycles, allowing larger powerboats to distribute climate loads smoothly over international shore lines or standard diesel generator panels without throwing main distribution breakers.

What airflow volume does this system deliver?

Flagship FM18RLP generates an airflow volume of 500 CFM. The integrated dual-stage low-profile centrifugal blower fan sweeps air evenly across expansive saloon areas, matching multi-cabin duct setups while running quietly against structural marine plywood bulkheads to keep interior sound footprints minimized.

Which vessels fit the Flagship FM18RLP?

Flagship FM18RLP is designed for custom motor yachts and deep-V express cruisers. Its flat, low-clearance chassis architecture fits perfectly into tight ceiling pockets or under shallow cockpit benches on vessels from thirty-eight to forty-eight feet, incorporating standard 100 percent cupronickel condenser plumbing loops for premium durability.
