CTM CW-36HS – Marine Chiller System 36,000 BTU – 230V – 50/60HZ – R410A w/Soft Start

Description

Boats with three or more independent cabins needing solid mid-range central chiller capacity have a proven option in the CW-36HS, delivering 36,000 BTU with a built-in soft start board. One verified owner running it for about a year called it a “great little chiller” and a trouble-free drop-in replacement for their old Dometic unit.

At this capacity, soft start genuinely matters for electrical planning — a 36,000 BTU compressor’s standard startup draw can strain a limited generator or shore connection, and the 65-75% reduction in inrush current the soft start board provides is often the difference between reliable starts and nuisance breaker trips.

Key Features of the CTM CW-36HS Chiller

This compact titanium chiller three cabins unit brings CTM’s proven soft start and titanium coil construction to a capacity that suits most mid-sized cruising yachts with multiple independent zones.

• Built-in soft start board reduces startup current by 65-75% compared to the compressor’s locked-rotor amperage
• Direct drop-in replacement for Dometic MCGX36 and TWCX36 chiller units, using the same DDC control board and controls
• Titanium condenser coil resists corrosion significantly better than copper in seawater applications
• Advanced MCC control board is a fully compatible replacement for the OEM DDC control board
• Corrosion-resistant metallic electrical box with effective grounding and EMI shielding

CTM CW-36HS Technical Specifications

These figures come from CTM’s official spec sheet for this listing. Current draw here is distinct from CTM’s smaller 24,000 BTU chiller listing, unlike the recurring figure overlap that’s appeared in some other CTM product lines — this unit’s specifications check out as internally consistent.

Why Choose the CTM CW-36HS

A verified owner’s real-world review backs up the trouble-free, drop-in nature of this replacement, and it’s covered by CTM’s standard 2-year warranty against material and workmanship defects. If you’re replacing a Dometic MCGX36 or TWCX36, the shared DDC control board makes for a genuinely simple swap.

What to Know Before Installing

• Confirm your vessel’s electrical system is genuinely wired for single-phase 220V/230V power before ordering
• This chiller requires separately specified CTM AH-series air handlers distributed to each independent zone
• Ships via freight given the 97 lb weight; commercial delivery address required
• If replacing a Dometic MCGX36 or TWCX36, this unit uses the same DDC control board for a straightforward swap
