CTM CX-48HN – 48,000 BTU Condenser – Marine Split A/C Unit – 230V – 50/60HZ – R410A NMEA 2000

Vessels in the 60 to 80-foot range often need more cooling capacity than any self-contained unit can practically deliver, and the CTM CX-48HN condenser handles that scale — 48,000 BTU with NMEA 2000 embedded control, built as a drop-in replacement for major split-system brands including Dometic, Cruisair, and Marine Air.

Why Choose the CTM CX-48HN

This is a condensing unit only — it requires a separate air handler (evaporator) installed in the living space, connected by insulated refrigerant lines, which is the fundamental trade-off of split systems versus self-contained units. That separation is exactly what makes split systems quieter in the cabin and more practical for large vessels running multiple HVAC zones off one or more condensers.

An EPA certificate is required before CTM ships any split condensing unit — factor that into your ordering timeline if you don’t already have one on file.

What to Know Before Installing

• EPA certification must be provided before shipping; contact CTM directly if you don’t have one
• Requires a separately purchased evaporator (air handler) unit — this listing is the condenser only
• Ships via freight due to size and weight
• Waterline connections should match your existing unit; the CX-48HN uses a 3/4″ seawater inlet
