Air handling unit filter monitoring

Ensuring good air quality in an industrial environment is essential to protect both employees and production. With this in mind, our instruments monitor air handling units (AHUs) and their filters.

For preventive maintenance, continuous monitoring of the differential pressure (ΔP) across each filter in an AHU prevents problems associated with clogging. This not only protects the health of employees and the quality of the products manufactured, but can also have a significant impact on controlling energy costs.

METROLOGICAL SERVICES
To guarantee the integrity of your pressure transmitters, our metrologists come to your site (France only). Drawing on our 45 years of expertise in metrology, they can carry out on-site calibrations and checks for all brands, often without dismantling equipment.
Our Montpon-Ménestérol laboratories specialise in all air parameters, and are also ISO 17025 accredited in thermometry and hygrometry. Two dozen experts are on hand to check and calibrate all your equipment if required.

DATA LOGGING & TRACEABILITY
Our differential pressure data loggers can be used for years to monitor air filters. This makes it possible to study the evolution of clogging in detail, so you can better rationalise replacement costs.
Equipped with lithium batteries, our units are easy to install and secure. They can be used to retrieve data via a wired connection (USB), but also via a wireless connection, or even LoRa (long distance and low power consumption) for the Tracklog model, which also provides SMS and email alerts.

SPOT MEASUREMENTS
Portable instruments give technicians greater mobility during preventive inspections. Technicians need to be able to reach pressostats and pressure transmitters without difficulty, thanks to lightweight, practical and accurate equipment.
Our portable manometers cover all the needs of technicians for spot measurements. Some simple, robust models can check the condition of filters. Other versatile and upgradeable models also measure speed and flow with modular probes.

CONTINUOUS MONITORING
Our differential pressure sensors monitor filter clogging and fouling to avoid production downtime due to maintenance. Our mechanical pressure switches can also generate the necessary alarms.
Particularly reliable and equipped with a self-calibration system, our top-of-the-range electronic transmitters are recommended for more effective monitoring: transmission of measurements to a control system, display of values, visual and audible alarms, etc.

  • Sauermann pressure sensors play a vital role in face mask tests
    Sauermann pressure sensors play a vital role in face mask tests

    As lockdown rules are eased in many parts of the world, the production of respiratory face masks is being ramped up to cater to massive demand from countries affected by the COVID-19 pandemic. Chinese filter manufacturers are turning in large numbers to Sauermann to certify their products to the strictest international standards. Filter test benches require high-precision differential pressure sensors, such as our CP 112 range, as part of the test protocol. Here, we explain how and why.

    Using CO2 concentration to measure air change rate

    Air change rate (ACR) has always been a key concept in building ventilation system management. But now, it’s become even more important – as a vital measurement in the fight against COVID-19, and against bacteria and viruses more generally.
