CTM CW-72H3 – Marine Chiller System 72,000 BTU – 230V – 50/60HZ – R410A – 3 Phase

Larger yachts running on 3-phase electrical systems have a dedicated option in the CTM CW-72H3, delivering 72,000 BTU of central chiller cooling built specifically for 208-240V 3-phase power. This three phase yacht chiller is a direct drop-in replacement for Dometic’s MCGX72 chiller line, sharing the same DDC control board and controls.

Choosing a 3-phase unit over the single-phase soft-start version matters specifically for boats already wired for 3-phase power — it avoids the compromises of running a single-phase compressor off a 3-phase supply, and in many cases 3-phase motors run more efficiently and with less vibration than an equivalent single-phase unit at the same capacity.

Why Choose the CTM CW-72H3

This unit carries CTM’s standard 2-year warranty against material and workmanship defects. Given the OEM substitution table error identified above, confirming the exact replacement part number with CTM directly before ordering — rather than relying on that table — is worthwhile if you’re matching this to a specific Dometic unit.

What to Know Before Installing

• Confirm your vessel’s electrical system is genuinely wired for 3-phase power before ordering this variant over the single-phase CW-72HS
• This chiller requires separately specified CTM AH-series air handlers distributed to each independent zone
• Do not rely on the OEM substitution table on this listing given the copy-paste error noted above — confirm replacement part numbers directly with CTM
• Ships via freight given the 167 lb weight; commercial delivery address required
