The LOUTANCE LM 515/516 Heat Transfer Oil Series is formulated for closed-loop industrial heating systems that require consistent thermal performance under long-term operation. Made with full synthetic base oils and advanced antioxidant additives, this product line supports continuous circulation at elevated temperatures, with a design focus on reducing system maintenance needs and sustaining heat transfer efficiency over extended service life. Two variants are available to match different operating conditions, with support for custom formulation to meet specific commercial procurement requirements.
The LM 515 and LM 516 thermal fluids maintain structural stability during prolonged circulation at oil temperatures up to 350℃. The synthetic base oil composition, paired with specialized antioxidant additives, slows the degradation process under sustained heat, reducing the formation of coking and sludge inside system pipelines. This property supports extended oil service life and reduces the frequency of fluid replacement for industrial operations, lowering long-term consumable costs for business buyers.
Hard carbon scaling on heating tube walls creates a thermal barrier that reduces heat transfer rates and increases fuel consumption over time. The formulation of the LM heat transfer oil series reduces the buildup of hard carbon deposits on heating tube surfaces. By limiting scale accumulation, the product helps systems retain consistent heat transfer efficiency during years of continuous operation, which supports controlled fuel costs for commercial users and reduces the frequency of manual pipeline cleaning maintenance.
The LM thermal fluid series is designed to be compatible with common sealing materials used in industrial heating systems, including rubber seals and gaskets. It avoids corrosive effects on these elastic components, which helps preserve seal integrity over time. This material compatibility reduces the risk of hot oil leakage caused by seal degradation, supporting safer and more stable system operation and reducing unplanned downtime for production lines.
Model | Characteristic Focus | Application & Limits |
|---|---|---|
LM 515 | Low Pour Point | Emphasizes low-temperature cold start performance. Max Temp 350°C. |
LM 516 | High Flash Point | Emphasizes extreme high-temperature operation & safety. Max Temp 350°C. |
The LM heat transfer oil series serves as a thermal medium for a range of closed-loop industrial heating systems across different sectors. The LM 515 variant, with its low pour point focus, is suited for systems that operate in low-temperature environments or require reliable cold-start capability, such as heating systems in cold climate manufacturing facilities and outdoor process heating setups.
The LM 516 variant, with its high flash point focus, is intended for systems that run at sustained high temperatures and prioritize operational safety. Common use cases include industrial boiler systems, chemical process heating, textile manufacturing heating lines, and food processing thermal systems. Both variants are designed for closed-circuit circulation systems, and are not intended for open heating configurations.
The LM heat transfer oil series is available in two standard packaging formats: 200L steel drums and IBC tanks, to accommodate different order volumes. For shipping, multiple transport methods are supported, including sea freight, air freight, and land freight, to match different order sizes and delivery timeline requirements. Accepted payment methods include T/T, L/C, and PayPal, to fit varied commercial procurement workflows across different regions.
The LM heat transfer oil series holds ISO 9001:2000, SGS, and RoHS certifications, covering production quality control and product safety compliance. For enterprise customers with specific operational requirements, OEM and ODM custom formulation services are available. Clients can request formulation adjustments to match particular temperature ranges, material compatibility needs, or performance priorities for their dedicated heating systems.
Both LM 515 and LM 516 heat transfer oils have a maximum rated operating temperature of 350℃ for closed-loop circulation systems.
LM 515 is engineered with a focus on low pour point performance, to support reliable system cold start in low-temperature ambient conditions. LM 516 is formulated with a focus on high flash point, for enhanced operational safety during continuous high-temperature running. Both models share the same 350℃ maximum temperature rating.
The LM series formulation is designed for compatibility with standard rubber seals and gaskets used in industrial closed-loop heating systems. It reduces corrosive effects on elastic sealing components to help maintain long-term seal integrity.
The product line is certified under ISO 9001:2000, SGS, and RoHS standards, covering production management and product compliance requirements.
Yes, custom formulation support via OEM and ODM channels is available for commercial procurement clients with specialized performance or application requirements for their heating systems.
