CTM CX-48HS – 48,000 BTU Condenser – Marine Split A/C Unit – 230V – 50/60HZ – R410A w/ Soft Start

Large yachts running on generator or limited shore power face a real electrical constraint that smaller boats don’t: starting a 48,000 BTU compressor can draw enough inrush current to trip a breaker or overwhelm an undersized generator. The CTM CX-48HS solves this directly with a built-in soft start board, letting the largest condenser in CTM’s split lineup start reliably even when power capacity is genuinely limited.

Beyond the electrical benefit, soft start technology extends the practical life of the compressor itself by reducing the mechanical stress of every startup cycle, and it makes the boat noticeably more livable — starting the AC no longer means a jarring surge that dims lights or trips other equipment running at the same time. For a vessel with multiple air conditioning zones, that difference compounds across every unit running soft start.

Why Choose the CTM CX-48HS

This is the unit to choose if your boat’s generator or shore power is genuinely limited, since soft start turns what would otherwise be a hard electrical requirement into a manageable one. It’s backed by CTM’s standard 2-year warranty against material and workmanship defects, giving real protection on what’s a significant investment for a large-vessel HVAC system.
