With Nexus technology, in addition to a chiller’s refrigeration system, a secondary microchannel heat exchanger system is added. Using proprietary economizer programming, this feature uses the outdoor air as the cooling medium whenever possible. This results in kilowatt-hour reductions of up to 60 percent, according to the manufacturer. Other features include predictive maintenance monitoring, variable-frequency drives and electronically commutated motor (ECM) fan technology.
