At the VDA Winter meeting 2009 HFO-1234yf was presented as the leading refrigerant alternative for MAC’s.

At the recent VDA Winter meeting (February 2009) held in Saalfelden, Austria, HFO-1234 was presented by DUPONT and Honeywell as the leading refrigerant alternative for Mobile Air Conditioning systems. The related presentations from DUPONT and Honeywell can be found under www.vda-wintermeeting.de.

Our range of Photoacoustic Gas Monitors INNOVA 1314 and INNOVA-1412 are well suited for measuring HFO-1234yf equipped with an optical filter, which shows an excellent linearity between 0.2 and 2000 ppm for HFO-1234yf. Of course our photoacoustic gas monitors can also be used to measure other refrigerants like CO2 or R134a as well. Please contact us or your local distributor for any additional information.

A number of OEM’s and suppliers in US, Europe and Asia, are using our instruments and find that the use of Photoacoustic Spectroscopy is a valuable and timesaving alternative.

The number of delivered instruments to measure HFO-1234 has significantly increased during the year 2009, as well number of upgrades of existing systems
