Multiple Variable Speed Secondary Pumps. 2-way valves at all chilled water coils and secondary bypass loop with 2-way valve. • Each primary pump pumps water through a chiller. These can be piped so either pump can work with either chiller if isolation valves are used at each chiller or with dedicated primary pumps for each chiller.
