Engineered for extreme performance, reliable wear protection, and optimized system longevity across global commercial operations.
Industrial gas and air compressors form the heartbeat of modern manufacturing, heavy metallurgy, petrochemical processing, and cold-chain logistics. Under the dual pressures of global carbon-neutrality mandates and high-intensity continuous production workflows, the criteria for selecting compressor oils have shifted dramatically.
Modern high-frequency rotary screw and centrifugal compressors operate under elevated thermal thresholds and severe oxidative stress. Synthetic fluids eliminate varnish precursor aggregation, protecting critical components such as the discharge valve assembly, oil separators, and precision bearings. This reduces mechanical drag, offering direct energy savings of up to 4% under full-load operation.
Procurement executives and engineering directors today evaluate chemical suppliers based on a strict matrix of Total Cost of Ownership (TCO), supply chain reliability, and technical compliance. The key requirements driving large-scale global chemical purchases include:
Established in 2009 and headquartered in Zibo, Shandong—a major hub of China's advanced chemical and industrial refining industries—Shandong Longhai Lubrication Technology Development Co., Ltd. is a high-tech enterprise integrating research and development, production, and international logistics.
Over the course of 15+ years, we have developed a complete industrial chain system. We operate our own brand "Century Longhai" alongside our international strategic partner brand, the British "A Ba" series. Our portfolio spans diesel engine oil, gasoline engine oil, gear oil, hydraulic transmission oil, anti-wear hydraulic oil, special engineering machinery lubricants, natural gas engine oil, fully synthetic fluids, automotive urea solutions, antifreeze, motorcycle special oil, industrial gear oils, and automatic transmission oil.
To ensure complete peace of mind, all our products are fully backed and insured by the PICC (People's Insurance Company of China), guaranteeing reliable quality insurance for global distributors and industrial operators.
Quality is the lifeblood of industrial lubricants. Longhai has achieved triple management certification: ISO 9001:2015 Quality System Certification, ISO 14001 Environmental Management System Certification, and OHSAS 18001 Occupational Health Management System Certification. In addition, our automatic transmission lubricants have received official Mercedes-Benz certification.
By adopting advanced production processes and high-precision testing technologies, we ensure that our lubricants maintain stable film thickness and high shear resistance, helping clients minimize wear rates and prevent thermal failures under severe operational conditions.
Leveraging automation, digital metering, and regional chemical supply chain synergies to deliver unmatched efficiency.
Located across a 131-acre high-tech production base in Zibo, Shandong, Longhai Technology operates an advanced industrial blending and packing center with an annual production capacity of 200,000 tons. By integrating Factory 4.0 automation concepts, we provide a resilient supply chain that ensures stable quality and quick delivery for global B2B buyers.
Our facility utilizes fully automatic blending systems and high-precision metering filling lines. Our filling technology operates on mass-flow metering principles, ensuring a filling accuracy deviation of only 1‰ to 2‰.
By stabilizing temperature, pressure, and chemical feed rates, this automated system increases filling speeds by 20% to 35% compared to traditional volumetric filling setups. This directly improves our delivery speeds, helping our customers maintain optimal inventory levels.
Our operations comply with major international quality, environmental, and occupational safety frameworks.

How our lubricants perform across demanding global industrial and commercial scenarios.
Chemical plants require air compressors to run continuously under high-load conditions. In these setups, any lubricant breakdown can result in varnish formation, leading to valve deposits, increased operating temperatures, and unscheduled shutdowns. Our synthetic compressor lubricants are formulated with high oxidative stability to minimize deposit buildup, helping plants keep their systems running smoothly between scheduled maintenance windows.
Mining machinery operates in harsh conditions, facing high dust levels, extreme vibration, and wide temperature swings. Standard oils can break down rapidly under these stresses. Our premium anti-wear hydraulic and gear oils are formulated with strong shear stability and robust additive packages, protecting gear tooth profiles and pump seals from abrasive wear.
Shipboard compressors and hydraulic steering systems are constantly exposed to moisture and saline air, which can accelerate rust and corrosion. Our formulations feature strong demulsibility, allowing water to separate quickly from the oil so it can be drained away. This helps protect internal metal components from rust and corrosion, extending the life of the machinery.
Hydraulic systems near smelting furnaces must operate reliably under intense radiant heat. Standard mineral oils can pose safety risks in these high-temperature areas. We formulate high-flashpoint synthetic oils that maintain stable viscosity even at elevated operating temperatures, providing reliable system protection.
Answering the most common technical questions from B2B buyers, procurement officers, and maintenance engineers.
High-performance formulations designed to protect machinery, extend service life, and maintain system efficiency.
Our lubricants support operations across diverse manufacturing and logistical fields.
