I. Core Composition and Refrigerant Compatibility
FVC32D is formulated with highly refined polyvinyl ether (PVE) as the base oil, combined with special additives, and is designed specifically for HFC refrigerants such as R134A, R410A, and R407C. Its core advantage lies in superior miscibility with refrigerants, enabling smooth circulation with the refrigerant, completely solving the oil return problem, and avoiding reduced heat exchange efficiency caused by oil accumulation in pipelines.
II. Key Advantages for Complex Operating Conditions
-
Hydrolysis Resistance & Anti-clogging: The polyether synthetic oil formula prevents hydrolysis-induced sludge formation and capillary blockage, ensuring unobstructed system operation.
-
Effective Lubrication & Equipment Protection: Excellent lubricating performance reduces wear on compressor components, effectively extending equipment service life.
-
High Compatibility & Safety: It possesses outstanding electrical insulation, suitable for various hermetic compressors, eliminating leakage risks, and is highly compatible with mainstream brand compressors such as Hitachi, Daikin, and Copeland.
III. Application Scenarios and Specification Advantages
FVC32D is compatible with various compressors including reciprocating, centrifugal, scroll, and screw types, and is widely used in commercial air conditioners, low-temperature cold storage, and industrial refrigeration units. The small packaging specification is an optimal choice for maintenance, meeting the convenience of on-site refueling.
IV. Selection and Usage Notes
-
Parameter Matching: With an ISO VG32 viscosity grade, a pour point as low as -47.5℃, and a flash point of 178℃, it can adapt to low-temperature operating conditions and high-pressure exhaust requirements.
-
Usage Taboos: Do not mix with other oils; seal immediately after opening to prevent moisture absorption from affecting oil performance.
As a time-tested oil product in the market, Daphne FVC32D builds a solid protective barrier for refrigeration systems with its core performance, making it an indispensable choice for pursuing efficient and stable operation.
