Description
Flagship Marine FM18RLP Low Profile Self-Contained Marine Air Handler
Featuring an advanced split architecture layout, the Flagship Marine FM18RLP engineering configuration delivers a dense 18,000 BTU/h cooling and reverse heating performance designed to stabilize isolated cabins up to 1,000 cu.ft. Utilizing compact 12.0×21.0x15.0-inch low-profile footprints, this robust condenser links directly to an automated blower network to clear space in machinery compartments. The design guarantees immediate thermal drops throughout tight overhead environments while maintaining structural versatility across specialized cruiser layouts as a premier low amp marine air handler solution.
Technology built into the single-phase 115V 60Hz control bus protects critical electronics while managing a 13.8A full load cooling draw and a 63A locked rotor startup spike. The 74 lbs structural chassis pairs an advanced evaporator assembly with high-efficiency cupronickel coils mounted in a stainless steel drain pan, damping acoustic noise levels during 16.5A peak electric heat operation cycles. Seawater loops sustain a 4.16 GPM fluid movement rate via 5/8-inch ports, completing a weather-sealed installation package equipped with a standard 6-inch duct discharge connection diameter.
Core Engineering and Performance Elements of Flagship Marine FM18RLP:
- High efficiency 18,000 BTU cooling and electric heating capacity
- Space saving low profile architecture fits restricted under bunk layouts
- Premium cupronickel condenser coils resist severe open ocean corrosion
- Heavy duty stainless steel base frame prevents structural rust leaks
- Low 13.8A full load cooling current draw efficiency profile
- Hermetic rotary compressor mechanics dampen operational sound emissions effectively
- Standard 5/8-inch seawater inlet and outlet plumbing pipe size
- Ignition protected design fully complies with modern boat layouts
- Compact 74 lbs structural chassis simplifies self contained installation
- Pre charged eco friendly R-410A system refrigerant tracking loop
Advanced Thermal Exchange Performance
Cupronickel condenser coils provide maximum thermal transfer by dissipating extreme heat while resisting harsh internal marine scale accumulation. The robust structural configuration balances automated refrigerant pressures across an optimized evaporator array, sustaining peak operating performance. This durable combination eliminates unexpected climate drop-offs under punishing high-salinity oceanic operational cycles, acting as a premium corrosion resistant boat AC platform.
Two Year Factory Warranty Protection
A comprehensive 5-year limited factory warranty protects your entire marine air conditioner investment against unexpected mechanical component failures. Factory certified technicians authorize immediate structural coverage for verified electrical and mechanical parts defects from the initial retail transaction date. Onboard operators receive absolute long term security, minimizing operational downtime while maintaining constant vessel comfort.
Vessel Layout and Application Fit
Vessels requiring 18,000 BTU cooling matrices achieve perfect environmental stability by integrating this targeted low-profile unit. The physical layout is custom-tailored for compact express cruisers or center consoles requiring under-bunk or overhead mounting with a minimal 4.5 kW auxiliary generator overhead. Proper installation ensures optimized structural airflow, maximizing onboard living space while reducing internal generator strain.

Flagship FM18RLP 115V AC FAQ
What voltage rating does this system use?
Flagship FM18RLP utilizes a standard 115V electrical feed. This configuration allows boaters to tap directly into traditional American domestic shore connections without multi-voltage transformer modifications, offering a high-capacity 18,000 BTU cooling and reverse-cycle heating solution that operates efficiently inside tight engine rooms.
How much does Flagship FM18RLP weigh?
Flagship FM18RLP features a net weight of 75 lbs. The slightly heavier 115V electrical windings are supported by a deep-draw marine-grade stainless steel condensate pan assembly that stops active corrosion and bilge sludge pooling without stressing narrow hull stringer grids.
Where is Flagship FM18RLP applied onboard?
Flagship FM18RLP is ideal for main salons and wide mid-ship master cabins. It delivers premium environmental control for express cruisers and commercial hulls lacking high-voltage utility lines, fitting effortlessly beneath shallow booth dinettes where its ultra-low height profile avoids encroaching on valuable cabin headroom.
