AirSep chooses HUMMINGBIRD sensors to deliver reliability and accuracy


AirSep Corporation has chosen HUMMINGBIRD Sensing Technology to deliver stable and reliable oxygen monitoring for its high purity production plants.

As part of a wide portfolio of oxygen generation products, AirSep’s Commercial Products Division manufactures High Purity Oxygen Plants, which are standard, single train, turnkey systems capable of a generation capacity of up to 3000 SCFH.

As the second stage of the high purity Pressure Swing Adsorption (PSA) process requires the further enhancement of produced oxygen purity from 95% to 98-99%, AirSep requires exceptionally accurate measurement to ensure this high level of purity is consistently maintained.

HUMMINGBIRD was approached by AirSep to help review and improve the performance of their existing installed analyser systems, with a goal of extending intervals between servicing times to minimise potentially expensive plant downtime.

In collaboration with AirSep’s development team, HUMMINGBIRD proposed replacing the existing analyser with the Pm1111E, a compact, fast-response sensor module which utilises a unique paramagnetic oxygen cell for fast, linear, highly stable and selective response in a non-depleting, rugged package. By delivering high accuracy, a long operating life and ultra-low calibration requirements, the Pm1111E was the ideal replacement to upgrade oxygen purity measurement performance for AirSep.

The result is highly accurate, reliable and stable oxygen monitoring suitable to meets the varied needs of AirSep’s customers, including hospitals and other medical applications, thermal or chemical oxidation, cylinder refilling and metal fabrication. Initial installations have already been highly successful, we understand, with ‘excellent performance’ being delivered to customers in the field.

“Our reputation is on the line every time we deliver or install an oxygen generating plant. There is no room for error, and the integrity of the components must be superior,” said Ravi K. Bansal PhD, who is AirSep’s CEO and Chairman of the Board.

“We have had success with the precision of Hummingbird sensors,” Bansal added.

“HUMMINGBIRD is delighted to have worked with AirSep to find the precise sensor solution for their requirements and help boost the plant performance in delivering high-quality oxygen production,” said Tommy Mikhail, Key Account Manager OEM Americas, HUMMINGBIRD Sensing Technology.
