AERCO's WaterWizard steam-to-water heater offers tight temperature control, longevity, reliability and low maintenance. AERCO's unique feed-forward monitoring system and high rangeability steam control valve maintain I4 degrees F temperature control. A two-pass, helical heat exchanger design and dedicated sub-cooling coil maximize efficiency and ensure condensate temperatures below 160 degrees F to preserve condensate return pump life. Doorway size and a 4'2" footprint simplify installation. The unit is compatible with low or high steam pressures and does not require a storage tank, trap or associated maintenance.
