Dorin Compressor Software What Can I Use It For & Brett Gets A TOOF Episode 529

Dorin CO₂ App Walkthrough + Heatwave Rack Chaos (Advanced Refrigeration Podcast)

Brett Wetzel and Kevin Compass open with jokes about Brett’s new tooth causing a lisp before diving into brutal Chicagoland heat (95°F+ for two weeks) and how it’s hammering CO₂ racks, especially systems without adiabatics. Kevin describes racks struggling at peak hours, capacity gaps where a second compressor is too large, VFDs stuck at minimum, low suction, rising discharge temps, overload trips, and heavy flash gas with bypass valves 50–60% open, with gas cooler outlet temps around 97–98°F (near ambient). They discuss limited quick fixes, defrost scheduling problems, and controller wiring/programming hurdles. Brett then screen-shares a training-style walkthrough of the Dorin app for sizing and troubleshooting, entering typical inputs to estimate compressor selection, discharge temperature, amperage, and using those values diagnostically to spot issues like valve plate blow-by rather than relying on pump-down tests.
