CTM CX-16S – 16,000 BTU Condenser – Marine Split A/C Unit – 115V – 50/60HZ – R410A w/ Soft Start

Vessels running on generator power, a limited shore connection, or an inverter system need a different approach to a 16,000 BTU compressor than boats with unlimited dockside electricity, and the CTM CX-16S delivers exactly that with a built-in soft start board. One verified installer described the setup as going in “well with no problems,” running copper lines from condenser to evaporator, pulling a vacuum, and testing for leaks without complications.

Soft start technology matters most when electrical headroom is the limiting factor rather than raw cooling need — it reduces the compressor’s inrush current by 65-75% compared to standard locked-rotor amperage, which is often the difference between a system that starts reliably on a 30-amp cord and one that trips a breaker every time the compressor cycles on.

Why Choose the CTM CX-16S

An installer’s real-world review confirms this unit goes in cleanly on new copper line installations, and it’s backed by CTM’s standard 2-year warranty against material and workmanship defects. If your boat runs on a generator or limited shore power, soft start is worth the added cost over the standard CX-16 to avoid nuisance breaker trips.

What to Know Before Installing
