Acoem Dynoptic air-purge bodies are designed to operate with an air flow into each body in the region of 50 to 200 litres/min. The lower flow rate is sufficient to overcome typical stack gas flow fluctuations and the upper flow rate is to prevent the flow of purge air from affecting the optical measurement.
Clean air is supplied to the purge air body which is installed directly in front of the monitor. The image below shows our stainless steel and aluminium purge air bodies.
Accessories for Emission Monitors
As well as emission monitors, Acoem Dynoptic can provide a range of accessories including Air Blowers and Compresses air kits to deliver the purge air to the monitors installed on a stack. Our Air Blowers can be specified with 110Vac, 230Vac single phase and 415Vac three phase power supply options.
As standard we supply and fit a high quality <5μm air filter to ensure the purge air itself is clean, air hose is also available to order. The image on the right below shows a typical installation with a single blower providing air to both sides of the stack via a T-piece hose connection.
Compressed Air Kits for Easy Installation
If compressed air is available near the monitor’s installation location Acoem Dynoptic can provide a compressed air kit comprising of a regulator, filter and fittings. Filtration of compressed air is important to remove contamination and traces of oil. This system does not require power so it is simple to install.
We have supplied 100s of blowers and compressed air kits to customer across the world, they are a reliable solution designed to work with our emission monitors making installation easy and ensuring long term, trouble free operation.
