Gas Conditioning Made Easy

he PGCS is a smart solution for stack testers looking to carry out frequent stack emission tests across different sites.

Stack testing is a procedure carried out by engineers to determine the concentration of gas and dust emissions being released into our atmosphere. Stack emission testing must be carried out to ensure that sites are complying with environmental standards. The amount of stack testing required is based on the size of the site and the amount of emissions, the greater the emissions the greater the need for continuous stack testing.

One of the UK’s largest MCERTS and UKAS accredited stack emissions testing contractors with extensive experience in the emissions testing industry has recently placed an order for a large quantity of Portable Gas Conditioning Systems (PGCS) from a1-cbiss ltd.

“Versatile and neatly packaged the PGCS is the perfect portable gas sampler for emission stack testers”

The a1-cbiss ltd PGCS is designed to ensure a clean flow and accurate sample of gas, correctly prepared for the analyser in gas monitoring systems. Whilst conducting 'on-the-spot' detailed gas analysis a gas conditioning system is required to remove particulates, cool gas, and eliminate condensation.

Housed in a compact, highly visible and robust carrying case and weighs just 12kg, the PGCS can be easily carried up the stack to conduct gas measurements.

The PGCS features a gas cooler that is equipped with an innovative heat exchanger system. The dew point is set at 4°C but can be changed at any value between 1°C and 15°C. Optional flow meters with integrated needle valves are available. The flow meters are built-in as the electronic controller. The exterior digital display from the gas cooler and flow meter gauge can be read whilst the carry case is closed. Any condensation is continually removed by the peristaltic pump.

A heated sample line that doesn’t require external power is mounted at the gas measuring inlet terminal inside the portable case. The amount of flow is determined by a sample gas diaphragm pump.

The portable gas sampling probe is connected to the heated line and is mounted within the stack for emissions testing.
