🏢 District Substation (Plate Heat Exchanger LMTD 3°F-5°F, Pressure Decoupling & BTU Meter)

Building Energy Transfer Station (ETS) Calculator

Size building Energy Transfer Stations (ETS / Alfa Laval / Danfoss) hydraulically decoupling high-pressure district distribution mains from low-pressure building HVAC systems: calculate plate-and-frame heat exchanger heat transfer with close approach temperature (LMTD 3 to 5 deg F), revenue-grade ultrasonic BTU billing meters, and district substation margins.
