Boiler Water: Semi-Instantaneous
Aerco Water Wizard 3E+
The most thermally efficient domestic water heating packages available for commercial and industrial use, these compact indirect-fired heaters offer tight temperature control, longevity and low maintenance all without the need for storage tanks, blending valves or other temperature averaging components. Now configured with a state-of-the-art electronic controls system, AERCO heaters are packaged to meet the remote control and integration needs of 21st century building managers.
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 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.
Packaged Heater - shipped completely assembled and ready for immediate hook-up; includes heat exchanger, your choice of electronic 2-way valve or pneumatic 2 or 3 way valve, and full controls package.
Bare Heater - heat exchanger only; insulation optional.

AERCO's exclusive Loadalert system continuously monitors water temperature and flow and modulates the flow of boiler water through the control valve and into the coils. Control panel with dual solenoid valve over-temperature limit system. One solenoid to disable boiler water control valve; One solenoid to perform as a secondary water relief valve. Panel also includes power on/tripped status lights and three liquid-filled remote capillary thermometers to display boiler inlet/outlet and DHW outlet water temperatures.
Dry Contacts - optional for remote "High Limit Tripped Status" indication.
