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 natural gas treatment equipment will design and configure the most suitable natural gas refrigerated air dryer for you, ensuring perfect integration with your natural gas system:

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

• Required pressure dew point (from 2℃ to -60℃, or lower according to your special requirements, to avoid ice blockage in low-temperature environments).

• Natural gas composition (methane content, moisture content, impurity content such as sulfur compounds, carbon dioxide, nitrogen).

• Working environment conditions (ambient temperature, humidity, installation space, corrosion level, anti-vibration requirements and other special needs).

• Special industry standards or certification requirements (such as CE, ASME, API, ISO and relevant natural gas safety certifications).

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

Optional Materials & Accessories

To ensure the durability, corrosion resistance, high efficiency and safety of the equipment, we select high-quality materials and accessories that meet international natural gas industry standards, supporting you to choose flexibly according to your on-site environment, industry characteristics and budget:
