TI-20W

The TI-20W is a 20.5-ton, water-cooled Titan central chiller — a full mechanical-room package with the compressors, evaporator, reservoir and process pump on one frame, using 2×10 HP scroll compressors across 2 refrigerant zones. The process pump moves 48 GPM at 60 PSI, and the reservoir carries 340 gallons of operating fluid volume — plenty of buffer to keep the compressor from short-cycling under a shift's normal load swing. Heat rejects to city or tower condenser water rather than an air-cooled coil, which is the reason to pick this frame over the equivalent air-cooled Titan model whenever plant water is already piped to the mechanical room and isn't metered at a cost that changes the economics. Charged with R-454B.
