The main purpose behind using Bio Gas Dehumidifiers is that it is used for removing moisture from biogas and increases CHP efficiency. Moreover, these products also help in lowering fuel gas consumption and also lowering down the requirement of oil changes. The corrosion resistance body of the available range minimizes the long term maintenance costs. These dehumidifiers does not require extra space to get installed, thus can be incorporated into existing systems. A standard design comprises of gas to the cold water heat exchanger that is equipped with an industrial grade water chiller. By reducing the temperature, dehumidification happens and water vapors get condensed. The use of these dehumidifiers can enhance the service life of an engine and allow them to perform efficiently.
