High-performance industrial fluids engineered for ultimate wear protection, oxidative stability, and thermal resilience under extreme pressures.
Established in 2009, Shandong Longhai Lubrication Technology Development Co., Ltd. (based in Zibo, Shandong) is a national high-tech enterprise at the forefront of the lubricant industry. Integrating research and development, manufacturing, global logistics, and bespoke application support, we specialize in high-end lubrication systems that keep industrial machinery operating at peak efficiency. Over 15 years, we have built a complete, vertically integrated supply chain, serving as a trusted supplier of industrial gear oils, compressor oils, hydraulic fluids, and synthetic motor oils.
Our core brand portfolio includes our proprietary flagship label "Century Longhai" along with the internationally cooperative strategic brand, the British "A Ba" series. Our products span a wide scope of industries, including diesel and gasoline engine oils, hydraulic transmission fluids, high-precision engineering machinery lubricants, eco-friendly natural gas engine oils, automatic transmission fluids, and high-performance antifreeze formulas. Every drop of lubricant leaving our facility is underwritten by the People's Insurance Company of China (PICC), offering peace of mind and robust risk mitigation for our global operational partners.
Modern air compressors operate under intense mechanical stress, high temperatures, and constant exposure to oxygen and moisture. The lubricant acts as a coolant, sealant, and wear preventive. Using low-grade compressor oil leads to varnish formation, valve deposit accumulation, and premature bearing failure. Our high-efficiency formulation prevents carbonaceous deposits and optimizes oil-water separation (demulsibility), ensuring smooth operation and low oil carryover.
A comprehensive look at chemical stability, operational efficiency, and supply chain strategies in the global lubrication industry.
Industrial screw, centrifugal, and reciprocating compressors represent the heart of manufacturing, chemical processing, and power generation. The operational lifecycle of these assets is directly proportional to the molecular integrity of their lubrication fluids. In the past, basic mineral oils sufficed. However, modern compact designs have increased specific power outputs, raising operating temperatures and putting severe oxidative pressure on the oil.
Longhai Technology's R&D team addresses this through advanced chemical formulations. Our air compressor and turbine oils utilize high-viscosity-index Group II and Group III base stocks, fortified with customized antioxidant, anti-rust, and anti-wear additive packages. By controling the molecular weight distribution, we minimize volatility, reduce oil carryover into the compressed air line, and prevent the formation of sludge and varnish. This results in significantly longer drain intervals—extending service life from standard 2,000-hour cycles up to 4,000 or even 8,000 hours under optimal conditions.
Why do global enterprises source lubricants from China, and specifically Zibo, Shandong? The answer lies in localized raw material integration, industrial cluster efficiency, and cutting-edge manufacturing automation. Shandong is the petrochemical heartland of China, providing direct, pipeline-supported access to premium base stocks and essential chemical reagents. This geographic advantage eliminates inter-provincial logistics costs and ensures a reliable material stream.
At Longhai Technology, we have capitalized on this landscape by constructing a 131-acre high-tech manufacturing park with a 200,000-ton annual capacity. Our blending facility utilizes computerized batch control systems that manage temperature, pressure, and shear rate with absolute precision. Our filling lines adopt high-precision metering devices, ensuring an accuracy rate of 1‰-2‰. Furthermore, this automation increases overall filling speed by 20% to 35%, allowing us to respond rapidly to sudden shifts in market demand, coordinate logistics, and complete bulk orders without quality variance.
Modern B2B buyers no longer purchase lubricants solely based on generic product catalogs. The diverse operating conditions of global projects—ranging from sub-zero mining operations in Siberia to hot, humid chemical plants in Southeast Asia—demand tailored fluids. Consequently, procurement directors look for manufacturers capable of flexible OEM/ODM modifications.
We address this shift through custom formulation services. Using our laboratory, we can adjust the pour point, viscosity index, detergent package, or friction modifiers of any lubricant to match specific target climates and mechanical tolerances. Whether a client requires low-toxicity, biodegradable hydraulic oil for marine applications, or high-performance synthetic diesel engine oil that meets strict Euro VI emission standards, our formulation engineers deliver products optimized for their precise operational profile.
From standard factory air systems to critical heavy transport, our fluids are developed for high reliability and protection.
Formulated for rotary screw, reciprocating, and vane compressors. Protects internal rotors from friction while managing the high heat generated during air compression cycles.
Prevents metal-to-metal contact in heavy reduction gears. High load-bearing capacity ensures smooth torque transmission under heavy shock loads.
Our refrigeration lubricants are chemically stable when exposed to modern refrigerants, maintaining low-temperature fluidity without forming waxy deposits.
Meeting strict international quality criteria to ensure seamless integration into global markets.
Operating in global markets requires compliance with international regulatory and quality frameworks. Longhai Technology is certified across three core ISO management frameworks: ISO 9001:2015 for quality management systems, ISO 14001:2015 for environmental protection, and ISO 45001:2018 (formerly OHSAS 18001) for occupational health and safety standards. Furthermore, our premium automatic transmission fluids carry direct approvals from global OEMs, including Mercedes-Benz. This proves our ability to produce fluids that match the exact chemical specifications of high-end automotive and industrial manufacturers.
For chemical safety compliance, we provide globally recognized documentation. Every product line is accompanied by comprehensive Safety Data Sheets (SDS) that follow the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). Our formulations also comply with European REACH regulations and ASTM testing methods. By providing technical data sheets (TDS) and batch analysis certificates with every shipment, we ensure our international clients clear customs quickly and maintain operational compliance.

Technical answers to common questions about industrial compressor lubricants, synthetic fluids, and global supply logistics.
Our compressor oils are formulated to meet specific demands. Our premium mineral formulations run for 2,000 to 4,000 hours under standard conditions, while our high-efficiency synthetic compressor oils (developed with Group III or PAO synthetic base stocks) operate reliably for up to 8,000 hours, depending on operating temperatures, system cleanliness, and air quality.
We ensure consistency through automated production and ISO 9001 quality protocols. Our blending plant uses computerized batching systems to manage temperatures and raw material inputs. Additionally, our on-site laboratory tests each batch for kinematic viscosity (ASTM D445), flash point (ASTM D92), and moisture content before shipping.
Yes. Our laboratory reverse-engineers or customizes formulations to match the viscosity profiles, load-carrying capacities, and chemical compatibility of OEM oils. We provide custom solutions for major rotary screw and reciprocating compressors, ensuring compliance with warranty requirements.
We support diverse packaging demands, including 1-liter and 4-liter retail bottles, 18-liter pails, and standard 200-liter steel drums. For bulk exports, we offer 1,000-liter IBC containers and flexitanks to minimize shipping costs per ton.
Compression produces moisture as air cools. If the oil cannot separate from water, it forms an emulsion that reduces film strength, leading to wear on bearings and rotor surfaces. Our lubricants ensure rapid water separation, allowing users to drain condensate without losing oil.
We provide full technical support, including custom packaging, multi-language labeling, chemical SDS files, and third-party laboratory reports. We also offer regional exclusivity agreements for volume importers under the "Century Longhai" or British "A Ba" brands.
