AERCO's unique feed-forward monitoring system and fully modulating control valves maintain +/-4°F water temperatures under the diversified load patterns of commercial domestic hot water applications. Performing with 90%-99% thermal efficiency, the unique 2-pass helical coil heat exchanger design of these single wall heaters is self-descaling and produces sub-cooled condensate (< 160°F ) to preserve condensate return pump life. All units are compatible with low or high steam pressures and do not require a storage tank, trap or associated maintenance.

 


PRODUCT OPTIONS
Packaged Heater - Shipped completely assembled and ready for immediate hook-up; includes heat exchanger, your choice of electronic or pneumatic steam valve, and full controls package.

Bare Heater - Heat exchanger only; insulation optional.

Materials of Construction
  • Standard: Copper or copper alloy wetted surfaces
  • Optional: 0.065" thick copper or copper-nickel tubing
ACCESSORIES
Domestic Water Storage Tank - AERCO storage tanks are ASME certified glass-lined pressure vessels designed for use with instantaneous water heaters. When contending with challenging applications they assure consistent hot water service during peak demands. The AERCO storage tanks are available in stratified or accumulator storage configurations.

Pressure Gradient Monitoring (PGM) System - Offered in lieu of double wall construction where codes allow.

Settings for Pressure Relief Valve
  • Standard: 150 PSIG, 212°F P&T
  • Optional: 230 PSIG for high-rise applications
CONTROLS
Electronic Controls -  AERCO's exclusive electronic control system combines a control box assembly with all circuitry, a flow meter installed at the cold water inlet for feed-forward sensing, feedback sensors and voltage regulator. To maintain optimal temperature control, the system utilizes PID algorithms to monitor outlet temperature and change control valve position. Easy-to-use digital displays are protected by clear-cover enclosure which can be locked. The system also includes an overtemp limit switch and water solenoid valve to function as a secondary water relief valve in an over-temperature condition.

Modbus Communications - Optional control board supports remote control and integration via Modbus protocol to Building Automation or Energy Management Software via RS-232 or RS-485 port.

Communications Gateway - Optional accessory supports integration with BACnet, LonWorks and N2 systems. Available only for heaters equipped with Modbus control board.

Pneumatic Controls - AERCO's exclusive Loadalert system continuously monitors water temperature and flow and modulates the flow of steam through the control valve and into the coils. Control panel includes pneumatic controller and dual solenoid valve over-temperature limit system. (One solenoid to disable steam control valve; One solenoid to perform as a secondary water relief valve.) Power on/tripped status lights, liquid-filled remote capillary thermometer and compound steam pressure gauge also included.

Dry Contacts - Optional for remote "High Limit Tripped Status" indication.
