EZ Plate Storage - a SUPERTANK® Water Heater


EZ Plate Storage

Available with AquaPLEX Duplex Alloy

EZ Plate® storage water heaters utilize a double-wall, brazed plate, heat exchanger to provide domestic hot water from boiler water. Plate heat exchangers are ideal for use with condensing boiler water systems because they allow the production of hot domestic water from lower temperature boiler water. Boiler water needs to only be 10˚F hotter than the desired domestic water temperature. The heat exchanger is external to the tank providing a smaller footprint than traditional u-tube storage water heaters. Heat exchanger and tank are connected with factory-assembled piping. Electronic operating control is Modbus connectable to a building automation system. No boiler water control valve is required with boiler water temperatures up to 180˚F. EZ Plate storage also offers dual heat exchanger models stacked to maintain the small footprint. These models can provide double the capacity or be run independent of each other, providing 100% redundancy. The heater allows for isolation of each heat exchanger to provide cleaning and maintenance without any system downtime.

Recoveries

  • Ten standard sizes from 600 to 5400 gph of water.
  • Recoveries will vary with differing boiler water temperature and domestic water temperature rise.

Storage

  • Vertical Orientation: 150 - 175 - 215 - 250 - 300 - 400
    - 500 - 600 - 750 - 900 gallons as standard. Custom storage
    tanks available from 1000 to 4500 gallons.
  • Horizontal Orientation: (custom) 250 - 400 - 500 - 600 - 750
    - 900 - 1000 - 1250 - 1500 - 1750 - 2000 - 2500 -
    3000 - 3500 - 4000 and 4500 gallons.

Boiler Water Control

No boiler water control valve is required when boiler water is 180°F or lower. Temperature control is maintained by an electronic operator on the storage tank controlling a circulator between the exchanger and the tank.

Optional 2-way boiler water control valve is available for boiler loops utillizing VFD on the main building circulator.

Corrosion Protection

  • AquaPLEX® engineered duplex alloy storage tank
  • Heat exchanger uses stainless steel plates.
  • All tank connections are non-ferrous and removeable. Lining protection is not compromised when pipe is threaded into fittings.

Certifications

  • Tank is ASME, section IV, part HLW stamped and National Board Registered.
  • Heat exchanger is ASME, Section VIII, part 1 stamped and National Board Registered.
  • Control panel is UL panel shop labeled.
