Flagship FM48CW 48000 BTU 230V Marine Water Chiller

Description

The smallest chiller in Flagship’s water-cooled lineup, the FM48CW delivers 48,000 BTU for boats making their first step up from split systems into centralized chiller cooling. This entry level marine water chiller shares the same compact 25″ x 15.5″ x 23″ chassis as the FM60CW, just tuned for a smaller cooling load.

Starting at this capacity tier makes sense for boats with two zones that want central-plant simplicity without paying for capacity they won’t use — and because it shares a chassis with the FM60CW, upgrading to more capacity later, if the boat’s needs grow, follows a known and predictable path within Flagship’s lineup.

Key Features of the Flagship FM48CW Chiller

This unit brings the same construction quality as Flagship’s larger chillers down to the smallest capacity tier in the water-cooled range, without cutting corners on the corrosion-resistant materials that matter most in a marine environment.

• Copper-nickel alloy (90/10 CuNi) condenser tube resists corrosion even in high-salinity waters like the Red Sea
• Dry, sloped aluminum drain pan prevents mold and mildew growth from standing condensate
• Low voltage diagnostic control module with labeled LEDs identifies high/low refrigerant pressure, freeze protection, and low water flow faults
• Laser-cut sheet metal components built to aircraft/military tolerances for a rigid, corrosion-resistant structure
• All 316 marine-grade stainless steel components throughout the unit

Flagship FM48CW Technical Specifications

These figures come from Flagship’s published spec sheet for this listing. As with the FM60CW, the page’s metadata lists a weight of 150 lbs while the specification table shows 179 lbs — the specification table figure is used here as the more likely accurate source.

• Cooling Capacity: 48,000 BTU
• Dimensions (L x W x H): 25″ x 15.5″ x 23″
• Amps (Cool): 22 A (voltage not specified on this listing — confirm with Flagship before ordering)
• Phase: 1
• Cycle: 60 Hz
• Net Weight: 179 lbs (spec table figure; product metadata lists 150 lbs — confirm with Flagship or CTM if exact shipping weight matters)

Why Choose the Flagship FM48CW

Flagship’s published warranty terms cover the condenser, chassis, compressor, and evaporator for five years parts and one year labor, with controls, pump, and blower covered for one year parts and labor. As the smallest chiller in the lineup, this is the lowest-cost path into central-plant cooling for boats that have outgrown split systems.

What to Know Before Installing

• Confirm exact operating voltage directly with Flagship, since it isn’t specified on this particular listing
• This chiller requires separately specified air handlers distributed to each independent zone — it is not a complete system on its own
• Ships via freight; confirm actual weight with Flagship or CTM given the discrepancy noted above
• Professional installation and electrical planning is strongly recommended
