Customization Process: What You Provide, We Customize

Adhering to a customer-oriented customization concept, you only need to provide us with the following key parameters. Our professional R&D and engineering team will design and configure the most suitable biogas refrigerated air dryer for you, ensuring perfect integration with your biogas system:

• Biogas handling capacity (Nm³/min or CFM), inlet pressure and inlet temperature.

• Required pressure dew point (from 2℃ to -40℃, or lower according to your special requirements).

• Biogas composition (methane content, hydrogen sulfide content, moisture content and other impurities).

• Working environment conditions (ambient temperature, humidity, installation space and special requirements such as explosion-proof, corrosion-proof).

• Special industry standards or certification requirements (such as CE, ASME, explosion-proof certification).

• Other special needs (such as cooling method, control system type, pipeline interface size, installation mode).

Optional Materials & Accessories
