The Patterson HSC pumps designed for the HVAC industry offer great selections
for chillers in the range of 300- to 2500-ton capacity. Their high efficiency and
rugged design is seldom equaled by other manufacturers. Typical of this are the

The advent of variable speed drives and digital control necessitated that we look
at the connection of chillers to pumps and ensure that the best piping

There is no single, best method of connecting chillers to pumps.
