Description

Technical Field

[0001] The present application relates to the field of skid-mounted compression equipment, and in particular to a two-stage compression device of skid-mounted compression equipment. Background Art

[0002] Skid-mounted compression equipment is a preassembled compressor system that integrates the compressor, control system, and auxiliary equipment into a sturdy frame or base, forming a complete unit. This design makes the compressor system very convenient for on-site installation, requiring only simple connections for immediate operation, reducing on-site installation time and costs. High-efficiency drying devices for skid-mounted compression equipment are designed specifically for compressed air systems, removing moisture from compressed air to meet the dry air requirements of various industrial applications.
