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 with rich experience in coal mine gas treatment equipment will design and configure the most suitable coalbed methane & gas drainage dryer for you, ensuring perfect integration with your mining and gas drainage system:

• Gas handling capacity (Nm³/min or CFM), inlet pressure and inlet temperature (adapt to low-temperature and high-humidity underground environment).

• Required pressure dew point (from 2℃ to -50℃, or lower according to your special requirements, to avoid ice blockage in underground and low-temperature transportation pipelines).

• Gas composition (methane content, moisture content, coal dust content, sulfur compounds, carbon dioxide and other impurity content).

• Working environment conditions (underground/mine site ambient temperature, humidity, dust concentration, anti-vibration, explosion-proof requirements and installation space limitations).

• Special industry standards or certification requirements (such as CE, ASME, ATEX, IECEx, coal mine safety certification).

• Other special needs (such as cooling method, control system type, pipeline interface size, mobile/fixed installation mode, dust-proof and waterproof requirements).

Optional Materials & Accessories

To ensure the durability, corrosion resistance, explosion-proof performance and high efficiency of the equipment, we select high-quality materials and accessories that meet coal mine and gas industry standards, supporting you to choose flexibly according to your on-site mining conditions, industry characteristics and budget:

Optional Materials
