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

Wireless differential pressure sensors are transforming HVAC systems. They offer a modern solution for monitoring filter performance in air handling units (AHUs). These sensors are crucial for maintaining optimal air quality and energy efficiency. They measure pressure differences across filters, indicating when maintenance is needed. Wireless technology simplifies installation by eliminating complex wiring. This reduces both costs and time, making it an attractive option for
