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 coolers series BCR03 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 vapour cross sensitivities and volumetric errors are minimized and damages of the sensible analyzer are avoided. With optional integrated peristaltic pumps for condensate removal complete devices series BCR03 ATEX are quick and simple integrable in sample gas conditioning systems. The coolers are specifically designed for operation in ATEX zone 2. ATEX-certification: II 3G Ex nA nC T4 Gc.
Technology
The precise proportional temperature control in combination with the long-lasting hot-gas bypass system and the innovative corrosion resistant heat exchangers achieves low extremely constant dew points. Also load fluctuations and high thermal stress is 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 cylinder is an effective cold storage that supports the compensation of unfavorable operating conditions. The BCR03 ATEX is equipped with exchangeable heat exchangers which allows an easy replacement without dismantling the device.
Functions
The cooling system of BCR03 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 a digital display for temperature monitoring and with a potential-free alarm contact. Two brackets allow a quick and easy wall mounting of the device.
