Explosion Proof Drying of Sample Gas

The full-range supplier and specialist for gas sampling and conditioning equipment AGT-PSG offers compressor coolers series BCR05 Ex for safe and reliable gas analysis in ATEX zone 1 and 2. The cooler is designed and manufactured according to the latest ATEX-guideline EN2014/34/EU. These high performance and low maintenance coolers are especially used for continuous extractive gas analysis. They serve primarily for exact constant lowering of the sample gas dew point and thus for drying of the humid sample gas flow. In this way water vapour cross sensitivities and volumetric errors are reliably minimised and damages of the sensible analyser are avoided.

The precise proportional temperature control in combination with the long-lasting hot-gas bypass system and the high performance heat exchangers achieves low extremely constant dew points. Also load fluctuations and high thermal stress are compensated reliably. The two mono or dual heat exchangers with one or two gas paths each are built in a solid aluminium cylinder which guarantees an optimal energy exchange between sample gas and cooling medium. In addition, the aluminum cylinder is an effective cold storage that supports the compensation of unfavorable operating conditions. The coolers are equipped with exchangeable heat exchangers which allows an easy replacement without dismantling the device. For drying of explosive sample gas AGT-PSG offers heat exchangers made of stainless steel for integration within tubed systems. Alternatively heat-exchanger materials PVDF or glass are also available.

The cooling system is filled with CFC-free refrigerant R134a. The sample gas cooler is equipped with an analog indication for temperature monitoring (unique on the market) and a potential-free alarm contact. The latest data sheet is available on the brand new website.
