Consistent comfort at the Norton Residence
To resolve these issues Nelson Mechanical installed motorized ball valves, balancing valves, a buffer tank and a pressure sensing circulator. On the four air handlers Belimo motorized ball valves were installed, giving complete control of the flow of chilled water without any water hammer or noise. Also installed were Victaulic balancing valves that determine and set the chilled water flow through each air handler — no more and no less than required. In the basement a 120 gallon buffer tank was installed — this met the outside chiller's requirement of a MINIMUM of 50 gallons of water in the system.
