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

Replacing AHU filters on a fixed schedule is simple—but it often wastes money or misses the moment performance starts to drop. Wireless differential pressure sensors solve this by continuously measuring the pressure drop across the filter, revealing clogging trends, efficiency losses, and the true end-of-life point. In this guide, we cover how differential pressure data supports condition-based maintenance, reduces energy waste, and improves indoor air quality—while enabling

Discover how conventional pressure monitoring falls short in optimising energy usage and minimising operational costs in building management
