COBREX® Steam Storage - a SUPERTANK® Water Heater


Cobrex Steam Storage

Available with AquaPLEX Duplex Alloy

COBREX® storage steam water heaters utilize a double-wall, copper-tube, counter-flow heat exchanger to provide moderate to large amounts of domestic hot water from steam. The heat exchanger is external to the tank and provides exceptionally little floor space to remove the exchanger, if necessary. Heat exchanger and tank are connected with factory-assembled piping. Electronic operating control is Modbus connectable to a building automation system. No steam control valve is necessary when inlet steam pressure is 15 psi or less.

Recoveries

  • Six standard sizes from 1200 to 7200 gph of water at a 100 degree rise with 15 psi steam.
  • Recoveries will vary with inlet steam pressure and temperature rise of potable water.

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.

Steam Control

No steam control valve is required when inlet steam pressure is 15 psi or less. Higher steam pressures utilize a pressure reducing valve to create 15 psi steam at the exchanger.

Corrosion Protection

  • AquaPLEX┬« engineered duplex alloy storage tank
  • Heat exchanger is 100% non-ferrous with copper tubes and brass tube sheets.
  • 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.
