Properties
BCRs are the allround talents among refrigerated coolers. They are installed in all applications where pure coolers are needed without additional conditioning equipment. BCR sample gas coolers can be optionally equipped with PVDF-, glass- and/or stainless-steel-heat-exchangers. Thus BCR sample gas coolers can cool down nearly every gaseous medium. The coolers are also very suitable for high gas flow rates and extreme high inlet temperatures. Even for operation in explosive atmosphere ATEX zones 1 and 2 BCR offers high performance systems.
Application
The high performance and low maintenance compressor coolersseries BCR05 ATEX are 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 vapor cross sensitivities and volumetric errors are minimized and damages of the sensible analyzer are avoided. Compressor coolers series BCR05 ATEXare specificallydesigned for operation in ATEX zones 1 and 2. ATEX-certification: II 2G Ex pxb de [ia] IIC T4 Gb.
Technology
The precise proportional temperature control in combination with the long-lastinghot-gas bypass system and the innovative corrosion resistant 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 aluminum cylinder which guarantees an optimal energy exchange between sample gas and cooling medium. In addition, the aluminum cylinderis an effective cold storage that supports the compensation of unfavorable operating conditions. The BCR05 ATEX is equipped with exchangeable heat exchangers which allows an easy replacement without dismantling the device.
Functions
The cooling system of BCR05 ATEX is filled with CFC-free refrigerant R134a. As heat-exchanger materials PVDF, glass or stainless-steel are available. The sample gas cooler is equipped with an analog indication for temperature monitoring and with a potential-freealarmcontact.Apre-mountedstableconsolewith vibration dampers for easy and safe wall mounting is available as option.
