Hackensack University Medical Center in New Jersey, a 781-bed teaching and research hospital, needed heaters to provide hot water to two buildings and for sterilization. Storage tanks, the usual solution, couldn’t be considered because of space restrictions in the 1,000-square-foot mechanical room.
To provide hot water for patients and 7,200 employees in the facility’s main building, the hospital selected AERCO’s A-Plus and B-Plus steam-to-water heaters. The units support intermittent flow rates of 115 GPM and 250 GPM without storage tanks. A vertical heater design requires about one-tenth the space of a storage heater designed for comparable service.
The facility also uses the WaterWizard high-efficiency hot water system to provide 130-degree hot water for sterilization processes. The system has a maximum intermittent flow rate of 250 GPM.
All units are controlled by an electronic control package to provide temperature accuracy within 2 degrees under constant load and 4 degrees under normal load changes. The controls are compatible with building automation or energy management software systems via Modbus open protocol.
