Explosion - proof Biogas Refrigeration Dryer

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 user's requirements And we've received universal praise from many customers.
Features Specifications Application
Scroll type compressors
Adekom refrigeration compressor was designed to give biogas users an extremely reliable source of compressed gas; combing world class explosion-proof the rotary or scroll type compressors adapted for the demanding conditions of the power generation applications. The customers can achieve its benefit of stable in operation with low noise level, reliable under extreme conditions, high energy efficiency from Adekom Refrigeration Compressor. Besides, the dryer Explosion-proof grade is Exde BT4, explosion-proof certificate can be offered. 
Heat exchanger and condenser are designed

Heat exchanger and condenser are designed in compact structure that is based on the high heat transfer efficiency can be achieved by maximum use of corrosion Resistant materials, such as copper pipe with pure aluminum fins or 304 stainless steel. As a result of all this, avoiding the secondary pollution for gas and supply customer the high quality dry compressed biogas.
Optimal refrigeration components 
Optimal refrigeration components are the most advanced product from the world brand such as DANFOSS and SPORLAN in United States and other brands, with thermal expansion valve throttle buck function, hot gas bypass valve energy regulation, Overload, high and low pressure refrigerant protection and other functions. 
Cooling system
Our design focuses on the extreme environment requirements for cooling system, such as: 
• Use of mine-used type cooling fan, reliability under extreme conditions
