Data Center Infrastructure Podcast - Ep 11 - How We Break Data Centers Before They Go Live w/ Mitch Dec of Data Airflow

New HFO refrigerants let closed-loop data center cooling match open-loop efficiency at a ~6-7 year payback on roughly $40M extra capex per $2B+ project.

• Commissioning levels L0-L5: Data Airflow's process runs from L0 (early design involvement) and L1 (factory witness testing of 100,000-lb equipment) through L4 functional testing with simulated GPU loads and L5 integrated testing that deliberately cuts power to prove A/B backup paths work.
• Closed-loop cooling economics: New HFO refrigerants (R515B, 1234yf) let closed-loop systems match open-loop energy efficiency; the capex delta is about $40 million on a $2 billion+ spend, with a 6-7 year payback via eliminated water chemistry, makeup water, and sewer costs.
