Update a New York school district’s 11 schools with 41 AERCO boilers.
A Long Island school district depended on AERCO boilers to provide heat during 95% of the heating season. We arranged for peak load to be augmented with cast-iron dual-fuel boilers. For maximum efficiency, an energy management system controls boiler firing rate, and hot water temperatures are reset from 180 to 100 degrees. Hot water pumps operate on VFDs to vary flow in response to changes in building load. AERCO boilers operate properly without primary pumps, isolation valves, or other flow.
Project Update: Since the original contract work was completed in 1997, the school district has built a 200,000 square foot middle school and a 350,000 square foot high school. The district wanted the newer, larger AERCO BMK-2.0 boilers to generate both heat and domestic hot water for both buildings year round.
GA Fleet supplied a propane air system that is fully integrated with the district?s EMS system. This consists of a buried propane tank with a vaporizer mixer (shown), and fully automatic controls and extremely tight safety features.
Beyond the high efficiencies provided by AERCO boilers, GA Fleet introduced an Interruptible Gas rate through the use of Propane-Air. This all-gas alternate fuel solution further reduced the school district’s fuel costs because it uses high-efficiency gas-fired — versus low-efficiency oil-fired — equipment.
