Removing moisture in gas conditioning systems made easy
Sep 08 2020 Read 416 Times
The removal of moisture is an essential step in extractive sample gas conditioning systems. However, this process generates excessive heat inside the cabinets and thus very often requires additional efforts like air conditioning.
The new gas cooler series TC- kit (+) from Bühler Technologies eliminates these extra efforts. Peltier elements as temperature transmitter are the middle part of a sandwich consisting of a heat sink with integrated fan forming the outer part and a cooling block with exchangeable heat exchangers and the attached electrical terminals as the inner part. For the installation a cut out has to be made at the appropriate side wall of the cabinet. The protection class of the mounted unit is IP 54.
With the heat sink geometrically larger as the internal parts, the unit slides into the cut out and finally is attached to the outside wall of the cabinet and sealed by a gasket. The electrical leads and the sample gas lines are kept inside the cabinet whereas the thermal load is dissipating to the ambient keeping the inside of the cabinet considerably cooler.
The TC Kit (+) requires 24VDC as power supply. As an option an extension unit for 115/ 230V AC supply is available and will be saddled directly to the basic unit. This extension also provides all neccessary connections to auxilliary units like sample gas and condensate pumps as well as moisture detectors and heated sample lines.
The operation parameters and alarm settings are programmable by a remote controller with digital display. This controller can be installed at an appropriate place inside the conditioning cabinet. The TC Kit+ version comprises special heat exchangers with minimised wash out effect as required by EN 15267-4 suitable for automated emission monitoring (AMS) systems.
