A major healthcare facility was struggling to maintain safe airflow, negative-pressure performance, and filter efficiency across its HVAC system—while still keeping energy and maintenance costs under control. In this case study, Ellenex deployed its NB-IoT PDT2-N differential pressure sensor with built-in temperature monitoring and the Ellenex Software Platform to deliver near real-time visibility, remote access, and predictive analytics. The result: earlier detection of perf

Hospital construction zones must remain under negative pressure to prevent particulates and potentially harmful airborne contaminants from migrating into occupied clinical areas. But fans, doors, and temporary barriers can make pressure stability difficult to prove—or to maintain consistently. In this guide, Ellenex explains how LoRaWAN-connected differential pressure monitoring provides near real-time visibility, threshold alerts, and reliable reporting across large faciliti
