industrial air curtains  Air curtains are widely used across the industrial sector — for warehouse doors, ovens, continuous dryers, or for air sealing and climate control when a heating module is included. They also help contain odours within production areas and prevent the loss of clean, conditioned air. Air curtains are an effective solution for odour confinement in food processing plants or waste management facilities, where it is essential that odours remain contained within designated zones.

  In waste management plants in particular, air curtains play a key role in operations, allowing transport access doors to remain open while keeping them sealed to stop odours escaping to the outside environment.

   Last Monday took place the 17th meeting of Working Group 41 (WG41) that is dealing on the new standard for Instrumental Odour Monitoring Systems (IOMS). This meeting was focusing on the statistics behind the Quality Assurance Level 1 (QAL1) of IOMSs. There are some aspects that make IOMS special as compared to other Automatic Measuring Systems (AMS) and one of these aspects is the cost of comparing the electronic signal of the IOMS with that of the reference method EN 13725.

   One of the key issues addressed many times during the WG41 meetings is that of the number of samples that should be taken in order to make QAL1 checks viable for IOMS manufacturers. Dynamic Olfactometry comes at a cost and odour is not a substance, it is a class. The question is: how many samples should be taken in order to have a representative picture of the IOMS performance?
