Mermaid M24 Cool and Reverse Cycle Unit – 24,000 BTU’s – 220 V 

Newest to the Mermaid Manufacturing line is the M24 – 24,000 BTU model marine air conditioner. Due to Mermaid customer demands, the M24 was created to solve the problem of locating a self-contained unit where performance, price, and efficiency were hard to find with an output larger than 16,500 BTU’s.

With a cooling capacity of 2,400 cubic feet, Mermaid’s 24,000 BTU unit is designed to cool over 40′ cruisers and over 45′ sailboats.

Constructed on Mermaid’s standard stainless steel base with dual condensate drains, the M24 is an ideal addition to any vessel looking for maximum performance and durability – all in one package. The M24 is available in Right, and Top air discharge configurations and only comes in 220V. The air output collar holds an eight inch duct. It is recommended to use at least three vents on this unit – minimum sizes of 6 inch vents. Mermaid provides eight inch ducting and air splitters to take eight inch to multiple six inch vents.

All M24 models include a digital thermostat, insulation mounting pad, and air output collar. Pump not included. 

With Reverse Cycle Heating

With reverse cycle heating in a marine A/C unit, a reversing valve reverses the flow of freon. Normally the evaporator / fan blows cold into the cabin while the condenser expels the heat into the water. When reversed, the evaporator / fan blows heat into the cabin and the condenser expels the cold into the water. Unit BTU ratings are based on it’s cool mode. The reverse cycle heat mode produces 10-15% more BTU’s than the unit does in cooling mode.

New redesigned unit features:

– Redesigned control box with more reliability and fewer components (if you need pictures please let me know)

– 30 amp resettable circuit breaker (replacing the 30 amp glass fuse)

– Improved thermostat

– Inverted drip tray with carrying handles.
