TECHNICAL DATA SHEET Innovation Commercial Water Heating System The AERCO Innovation Water Heater utilizes state-of-the-art technology to easily meet highly diverse, demanding commercial and industrial hot water requirements in a compact and reliable condensing design. The durable high efficiency helical firetube heat exchanger is time tested to be impervious to thermal stress for an extended life. The all stainless steel construction maximizes longevity in the condensing application and the corrugated tubes increase effective heat transfer surface area for optimal thermal efficiencies up to 99%. Enhanced waterside flow distribution maintains constant minimum velocities across the heat exchanger; this keeps solids in suspension and greatly reduces scale dropout to maintain high efficiency performance and long life. The advanced control system of the Innovation incorporates dynamic feed-forward sensing for precise modulation of its 18:1 turndown air/ fuel delivery system. These controls fire the unit to accurately match load requirements and produce tight hot water outlet temperature control. Wasteful overshooting and cycling are virtually eliminated as is the need for storage tanks, mixing valves and other temperature averaging components in most applications. The set point is adjustable from 50°F to 190°F and control to +/- 4°F is easily achieved. Sidewall, through–the–roof, and sealed combustion capabilities provide broad installation flexibility. The small foot print, doorway size, and quiet operation make it ideal for retrofit. With its tight temperature control, high efficiency, reliability and longevity the AERCO Innovation is truly unique and advanced design.
