High-performance engineering solutions specialized for extreme operating pressures, high-temperature diesel and gasoline powertrains, dynamic gearboxes, hydraulic transmissions, and modern compressor systems.
Modern industrial infrastructure relies heavily on compressed air systems as a core energy utility, often described as the "fourth utility" alongside electricity, water, and natural gas. Globally, heavy industries, petrochemical refineries, pharmaceutical facilities, packaging plants, and automotive manufacturing complexes require non-stop compressor operation. The operational reliability of these mechanical units is deeply connected to the chemical performance of the lubricants running within them.
Under demanding operating conditions, air compressor lubricants face massive mechanical and chemical stress. Rotary screw and reciprocating compressors compress air, generating localized high temperatures and putting the lubricant in constant contact with atmospheric oxygen, moisture, and particulate contaminants. Standard lubricants degrade under these conditions, causing molecular breakdown, oxidation, varnishing, and carbon deposits on rotors and valves. This leads to component wear, increased energy consumption, and catastrophic system downtime.
Preventing molecular thermal cracking at extreme discharge temperatures (up to 110°C in continuous operation) to ensure viscosity retention and prevent varnish buildup.
Compressors continuously condense atmospheric moisture. High demulsibility prevents the oil from forming water-in-oil emulsions, protecting internals from rust.
Limiting polymerization of base oils when exposed to hot compressed oxygen, which significantly extends fluid life and lowers filtration costs.
Over 15 Years of Precision Lubrication Innovation, Engineering Excellence, and Global Scale Delivery.
Established in 2009 and headquartered in the industrial chemical cluster of Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. has grown into a premier high-tech enterprise integrating R&D, advanced blending, automated production, and global supply services. With a production base covering over 131 acres and an annual blending capacity reaching 200,000 tons, we serve as a reliable, large-scale partner for international wholesale buyers and industrial distributors.
Longhai Technology manages its flagship brand "Century Longhai" alongside the internationally cooperative British "A Ba" series. Our diverse portfolio spans automotive, heavy-duty transportation, and heavy industrial lubrication fields, including specialized diesel engine oils, high-viscosity gear lubricants, anti-wear hydraulic transmission fluids, and synthetic air compressor formulations. All premium products are fully backed by PICC (China People's Insurance Company) quality liability insurance, offering peace of mind to our worldwide distribution partners.
Longhai's advanced production facility utilizes high-precision automated blending systems and automated packaging lines that leverage raw-material metering technology. This design achieves a filling precision of 1‰ to 2‰, minimizing fluid waste and ensuring consistent container net weight. By transitioning to computerized, multi-channel automated filling systems, we have improved filling throughput by 20% to 35% compared to traditional batching plants. This allows us to rapidly complete bulk international orders while maintaining strict batch-to-batch consistency.
Located in Zibo, Shandong, our facility benefits from access to petrochemical pipelines and base oil refinery structures. This geographic advantage guarantees a steady supply of Group I, Group II, Group III base stocks, and synthetic polyalphaolefins (PAO) or ester bases. Our long-term relationships with international additive developers (such as Lubrizol, Infineum, Afton, and Chevron Oronite) ensure that we use only high-performance anti-oxidants, anti-wear agents, and demulsifiers in our formulations.
Zibo's proximity to the deep-water Qingdao Port allows for efficient maritime logistics, offering direct routes to major global hubs. This integrated supply chain reduces shipping times, protects clients from logistics disruptions, and ensures reliable cargo space during peak global trade seasons.
Compressor operating conditions vary widely depending on geography and application. As a global OEM/ODM manufacturer, Longhai designs customized formulations tailored to specific localized environments:
In regions like South America, North Africa, and the Middle East, high dust levels challenge compressor systems. Longhai's compressor lubricants feature advanced dispersion chemistry to prevent dust particles from agglomerating, protecting rotors from abrasive wear.
For operations in Eastern Europe, Northern Asia, and North America, compressors must start reliably in sub-zero temperatures. Our synthetic PAO fluids offer low pour points (-45°C) and low starting torque, protecting equipment and saving energy on cold starts.
Offshore oil rigs and marine vessels experience high ambient humidity and salt spray. Our lubricants are formulated with specialized corrosion inhibitors to protect yellow metals and steel parts from saltwater-induced corrosion.
To keep pace with more compact compressor designs, higher operating pressures, and global sustainability goals, Longhai Technology maintains a strict research and development roadmap:
By using hydrocracked Group III base oils with high viscosity indexes, we offer mineral-like cost-efficiency combined with performance that approaches semi-synthetic fluids. This extends typical drain intervals up to 4,000 hours in standard rotary screw installations.
Developing polyalphaolefin (PAO) and polyol ester (POE) blends that resist thermal oxidation. These synthetic formulations prevent varnish deposits, lower energy consumption by reducing fluid friction, and extend oil life up to 8,000–10,000 operational hours.
R&D focused on biodegradable synthetic esters and food-grade lubricants (NSF H1 compliant) to serve environmentally sensitive sites, agricultural packaging lines, and pharmaceutical cleanrooms.
Longhai Technology offers end-to-end customization services, helping international brands launch high-quality lubricant lines tailored to local market needs:
Analyzing operating environments, viscosity targets, base oil specs, and target drain intervals.
Selecting base oils and additive packages in our laboratory to meet custom specifications.
Running viscosity tests, oxidation tests, foam tests, and demulsibility trials to verify performance.
Utilizing our automated filling lines to deliver consistent, packaged, and labeled products on time.
Our commitment to quality is backed by international certifications, confirming that our management and manufacturing processes meet strict global standards:
Our laboratory performs rigorous tests using ASTM standards on every batch before shipment, checking parameters like kinematic viscosity, flash point, pour point, water content, copper corrosion, and foam stability. We provide Certificate of Analysis (COA) documents for all outgoing shipments.
