Flagship FM120CW – Chiller 120,000 BTU’S – 230V – Cool Only
At 120,000 BTU’S, Flagship FM120CW provides cool-only marine chiller capacity using 230V power for large onboard cooling systems.
- 120,000 BTU’S handles substantial cooling.
- 230V supply guides electrical planning.
- Cool-only output excludes heating functions.
- Chiller format supports centralized climate systems.
- FM120CW identifies the model.
Mid-to-large yachts with a handful of independent cooling zones — rather than the dozen-plus of a megayacht — find their match in the Flagship FM120CW, delivering 120,000 BTU from a central water-cooled plant. This mid size yacht chiller shares the same copper-nickel condenser and 316 stainless steel construction as the rest of Flagship’s lineup, just sized for a smaller vessel category.
The practical benefit of a chiller at this capacity is flexibility for future zones: a boat that adds a cockpit enclosure, a flybridge cooling zone, or converts a storage area into living space can often tap into existing chiller capacity rather than installing an entirely separate split system, provided the central plant has enough headroom.
Why Choose the Flagship FM120CW
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. Given the phase notation discrepancy above, verify your electrical configuration with Flagship or CTM before finalizing your order.
What to Know Before Installing
- Confirm actual voltage and phase configuration directly with Flagship given the discrepancy noted in the specifications above
- This chiller requires separately specified air handlers distributed to each independent zone — it is not a complete system on its own
- Ships via freight given the 490 lb weight; commercial delivery address required
- Professional installation and electrical planning is strongly recommended at this capacity
