The Tranquility^® SW Water-to-Water Series from ClimateMaster offers a flexible, energy-efficient solution for radiant floor heating, chilled water for fan coils, and snow/ice melt systems. Available in sizes 036–120, the SW Series now features two-stage compressors on sizes 036 and 060, delivering improved part-load efficiency and quieter performance.

With vFlow^® unit-integrated variable-speed water pumping on source and load sides (036 and 060), and an optional modulating water valve, the system precisely matches water flow to load demand—enhancing energy savings and control. DXM2.5 advanced communicating controls are standard on sizes 036 and 060, while dual CXM2 controls support size 120 for dependable operation and monitoring.

The SW Series also includes a factory-installed compressor soft-starter, integrated power disconnect, and front-facing service access, allowing side-by-side installation to simplify multi-unit layouts.

A key advancement is the reduced cabinet footprint compared to the previous TWM series, streamlining equipment room layouts and maximizing usable space without compromising capacity or serviceability.

ClimateMaster’s Tranquility SW is built for performance, precision, and efficiency—meeting modern water-to-water system needs with a smarter, smaller package.
