About Ever-Power
A legacy of compressor engineering excellence since 1951
Heritage & Evolution
Ever-Power traces its roots to one of China's earliest gas compressor manufacturers, established in 1951. Originally a state-designated key enterprise in the national compressor industry, the company underwent comprehensive shareholding restructuring in 2000 and completed a major facility modernization in 2010. Today, our headquarters in China anchors global operations, with our Singapore branch office serving as the strategic hub for international sales, technical support, and ATEX compliance certification.
Integrated Manufacturing
Our campus features dedicated production facilities including a foundry, precision machining center, pressure vessel fabrication shop, and final assembly plant. A fully equipped compressor research institute drives continuous innovation in piston ring materials, valve dynamics, and thermal management. Supporting departments span sales, marketing, aftermarket service, finance, manufacturing planning, supply chain, process engineering, and quality assurance.
70+ Years of Compressor Excellence
From pioneering air compressor design to leading ethylene and process gas compression technology
Entered Process Compressor Manufacturing
Began mass production of medium-high pressure ammonia gas compressors (2D6.5–6.7/150 series) for domestic fertilizer plants, marking our entry into the process compressor sector.
Pioneered Screw Compressor Development
Commissioned by the Ministry of Machine Building to develop China's first screw air compressors, establishing Ever-Power as a trailblazer in domestic screw compressor design.
National Quality Recognition
The L5.5–40/8 air compressor received the "Quality Trustworthy Product" award from Jiangxi Province and the Ministry of Machine Building.
First Oil-Free Air Compressor in China
Commissioned by the Ministry of Machine Building to develop the nation's first oil-free lubricated air compressor series, positioning Ever-Power as an industry leader.
National Silver Quality Award
The 4L–20/8 air compressor earned the Ministry's "Quality Trustworthy Product" certificate and the National Silver Quality Medal for product excellence.
State Mechanical Commission Award
The ZL3.5–20/7 foundation-free air compressor received the "Quality Product Award" from the National Mechanical Commission.
National Key Product & Innovation Award
The oil-free LW–6/40 air compressor for PET bottle blowing was designated a national key product. The same series won Jiangxi Province's "Excellent New Product" Second Prize.
VFD Acetylene Compressors & Industry Standards
Launched variable-frequency acetylene compressors (2Z–0.8/25, 1.34/25, 1.82/25 series) for welding gas applications. Led the drafting of the national industry standard for reciprocating acetylene compressors.
Petrochemical & Energy Sector Expansion
Began mass production of process compressors for petroleum and chemical industries, supplying Sinopec, CNPC, CNOOC, State Power, and coal mining conglomerates.
Largest CO₂ Compressor in China & National Standards
Delivered the 4MW–147/29 CO₂ compressor — the largest single-unit displacement in China — to CNOOC Lishui for oilfield gas recovery. Led the drafting of the SAC/TC145 national standard for medium-pressure CO₂ compressor design and manufacturing.
Technology Upgrade & Product Modernization
Adopted and assimilated advanced international technologies to optimize traditional process compressor designs and execute a comprehensive product generation upgrade.
