‘A gas leak becomes evident only after the system runs out of it’

CORNAREDO, Milan, Italy, 12 February 2021: One of the weak points in a gas detection system, especially in refrigeration applications, is that it is almost impossible to detect a small leakage in the plantroom. Dr Giacomo Frigo, Founder & Managing Director, Sensitron, said this, adding that the management realises the leakage only when there is no more gas in the system.

Dr Frigo pointed out to how hotel chains have started installing fire detectors to be able to assure guests that no accidents will occur in their hotel room. Much in the same way, he said, the right step forward would be to install gas detectors that give out a warning much before an alarm does, to improve the management of a gas detection system.

Hand in hand with installation is the maintenance of the detectors, he said. In Sensitron, for instance, we have adopted the NDIR technology in all our detectors, which he said is a bit more costly than the MOS technology. The additional cost, he added, is worth it, because the alarm value from the detector is much more stable and accurate. As a result, he further added, the period of checking and recalibration of the detector practically is three time longer than that of other systems.
