Dometic TWCX CW Module

Modular Titanium Chiller from 24,000 BTU/h to 72,000 BTU/h

Dometic TWCX with Digital Diagnostic Control (DDC) is a high-performance, cost effective tempering unit. The reverse-cycle TWCX cools and heats, and is available in an expanded product range of 24,000 (2-ton) to 72,000 (6-ton) BTU/h capacities. Units can be multiplexed for even larger capacities as required. : 9108893826

Compact Enclosed Chillers With Titanium Durability

Dometic TWCX Titan compact 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. Titan service life is greatly extended compared to cupronickel systems – the industry standard – which inevitably suffer catastrophic failure from corrosion and erosion in the harsh marine environment. Each unit includes a chilled water (CW) flow switch, refrigerant high- and low-refrigerant pressure switches, and inlet and outlet CW temperature sensors. The TWCX does not include a chilled water modulating flow control, which means air handlers with or without flow controls can be used. On larger boats we always recommend using flow-controlled air handlers to ensure proper water distribution. A balancing flow control (BFC) is not needed when using TWC chillers.
