Generalize：Biogas refrigeration dryer is a special drying equipment usually using to remove biogas water vapor to reduce the pressure dew point. For the biogas as the fuel, most of the impurities and water vapor have to be removed as they may cause corrosion, deposits and damage to equipment. For instance, biogas at the compressor outlet usually has a very high water vapor content with high temperature. It is therefore essential to use a cooling system such as the refrigeration dryer to produce low dew point by freeze-drying dehydration. And then dry compression gas can be supply for the generator application, which prevent the generator unit and the end of gas accessories from corroding, rusting damage and this like. And this dry compression biogas that produced from biogas refrigeration dryer can be supplied as renewable energy for generating electricity. It is an effective way of implementing environment protection and saving resources and energy. We are especially experienced in the design and manufacture of biogas refrigeration dryer, which has started research and development since 2008 in the domestic, the products have been widely used in landfill gas, sewage treatment and power generation applications and other industries to meet end users' requirements And we ‘ve received universal praise from many customers.
