B+II WaterWizard

Our most popular steam-to-water package, the B+II WaterWizard features dedicated sub-cooling capabilities for enhanced operating efficiency.

AERCO's unique feed-forward monitoring system and fully modulating control valves maintain +/-4°F water temperatures under the persified 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.

ACCESSORIES

AERCO Digital Mixing Station (ADMS)
If local code mandates use of a mixing valve or for storage tank or two temperature applications with AERCO water heaters, it is recommended to use an AERCO digital mixing station. Lead-free, ASSE 107 certified ADMS is a smart water tempering system that allows temperature controlled distribution of potable hot water throughout the loop. The building automation system (BAS) ready ADMS™ can be configured with strainers, building recirculation pump and Flow/BTU monitor package to allow facilities managers to remotely monitor and control distribution water temperatures along with monitoring of flow and energy consumption.

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.


CONTROLS

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

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

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.

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.
