Chilled Water Air Conditioning

MTS 25-Ton Modular Chillers

For Large Vessels & Super Yachts

The MTS is a high-capacity modular chiller unit for large pleasure yachts and commercial vessels. Optional electric heaters can provide air conditioned comfort onboard year round.

Each module contains a hermetic scroll compressor and shell-and-tube marine-grade condenser, along with other mechanical and electrical components on a single chassis. Multiple modules can be staged as needed to meet the required load.

• Modular design for staging multiple units.
• Hermetic scroll compressor avoids leaks.
• Marine-grade cupronickel tube-and-shell condenser.
• Dual bottom-draining liquid connections and trap in condenser for optimal performance in choppy seas.
• High-pressure switch and pressure-relief valve for safety.
• Optional frequency drives available to minimize starting amps.
• Filter drier keeps refrigerant oil clean and dry for long compressor life.
• 100% pump-down capacity for refrigerant circuit repairs without having to recover the refrigerant.

CHCG Series Compact Modular Chillers

Compact Module In An Enclosed Design
Now with R410A refrigerant, The CHCG series of modular compact chillers is ideal for larger boats in the 45-70 ft. (15-20 m) range. The new CHCG series harnesses the impressive performance of R410A in the same space-saving footprint as the older CHC units.

MCGX Titan Chillers

Dometic MCGX modular chillers use titanium condensers to greatly increase durability and product lifespan. Titanium is unaffected by the punishing combination of saltwater, invasive marine life, and the harsh acids used for routine cleaning of the condenser coil. Titanium extends service life and is unaffected by the corrosion and erosion of the harsh marine environment. Go to the MCGX Titan Chillers page for specifications and more.

SCW Staged Multi-Ton Chillers

Staged Chilled Water (SCW) chillers are available in capacities ranging from 48,000 (4 ton) to 1,080,000 (90 ton) BTU/hr. SCWs are available in single- or three-phase, 50Hz or 60Hz, and all standard voltages (208, 230, 380, 460 VAC). Multiple compressors and refrigerant circuits are incorporated to provide minimal power consumption versus load demands, as well as redundancy throughout the system. Each condensing unit is monitored and protected with freeze controls, high-limit switches, high and low aquastats, times, and onboard fuses or breakers.
