Chiller Replacement

Chiller technology in the past few years has improved tremendously, as evidenced by the remarkable gains in efficiency in these large machines. From typical averages of 1 kW/ton in the 1980s, today’s chillers can achieve power consumption levels as low as 0.34 kW/ton with typical operating ranges in the 0.5-0.6 kW/ton levels.

In this example, a 160,000 sq. ft. telecommunications facility underwent a chiller replacement. The piping system was converted to primary-secondary, VFDs were utilized on one chiller and some of the pumping, cooling towers were replaced, and a new set of digital controls were implemented. From our specifications, these changes resulted in a highly efficient system that is easy to operate.
