CTM Marine CW-24H 24000 BTU Marine Chiller System

Description

The smallest chiller in CTM’s CW lineup, the CW-24H delivers 24,000 BTU for boats making their first move from split systems into central chiller cooling, without the added cost of a soft start board that most boats at this capacity don’t strictly need. It’s a direct drop-in replacement for the Dometic TWCX24 chiller unit.

Starting at this capacity makes sense for boats consolidating just two or three zones, and because CTM’s CW lineup shares control board architecture and titanium coil construction across every capacity tier, moving up to a larger chiller later — if the boat’s cooling needs grow — follows a predictable, well-documented path.

Key Features of the CTM CW-24H Chiller

This smallest ctm chiller system option brings the full CW feature set down to the entry capacity tier, without compromising on the titanium coil construction or DDC control board compatibility found across the range.

• Direct drop-in replacement for the Dometic TWCX24 chiller unit, 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
• The lightest and most compact chiller in CTM’s CW lineup at 75 lbs

CTM CW-24H Technical Specifications

These figures come from CTM’s official spec sheet for this listing. Worth flagging: this current consumption figure (7.6A/9.0A) is identical to figures published across several of CTM’s 24,000 and 36,000 BTU condenser listings in the split-system CX line, a pattern that has now also appeared here in the CW chiller lineup — confirming exact current draw with CTM directly is worthwhile if precise electrical planning matters.

• Capacity: 24,000 BTU
• Voltage: 220V/230V
• Phase: Single phase (dual cycle compressor: 50Hz at 220V / 60Hz at 230V)
• Refrigerant: R410A
• Current Consumption (Cool/Heat): 7.6 A / 9.0 A (identical to figures published across several other CTM condenser and chiller listings — confirm with CTM directly if precise sizing matters)
• Locked Rotor Amps: 42 A
• Fuse Max/Min: 25 A / 16 A
• Seawater In/Out: 5/8″ / 5/8″
• Chilled Water In/Out: 3/4″ / 3/4″
• Suggested Water Flow: 500 GPH
• Dimensions (W x D x H): 14.1″ x 9.8″ x 18.9″
• Net Weight: 75 lbs

Why Choose the CTM CW-24H

This is the most economical way into CTM’s chiller platform, backed by CTM’s standard 2-year warranty against material and workmanship defects. Given the current draw overlap noted above, the locked rotor amps and fuse rating are the more reliable figures for breaker sizing in the meantime.

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
• Confirm actual current draw with CTM given the data overlap noted above
• Ships via freight given the 75 lb weight; commercial delivery address required
