Targeted Lubrication Solution for Modern Refrigerant Systems
Qishanr QSL-32H positions itself as an advanced refrigeration compressor oil tailored for equipment utilizing HFC refrigerants such as R-134a, R-404A, R-407C, and R-410A. Developed by a reputable refrigeration oil manufacturer, this poe refrigeration oil is intended for professionals managing screw, centrifugal, scroll, and reciprocating compressors in HVAC&R applications. The product addresses the needs of OEMs and service providers requiring a lubricant that aligns with stringent specifications while ensuring system reliability and protection in demanding operational environments.
Advanced Chemical Stability and Precise Viscosity Control
This synthetic refrigeration oil offers substantial chemical and thermal resilience, resisting degradation and interactions with refrigerant and metal components, thereby sustaining compressor performance over time. With an ISO VG32 viscosity grade, QSL-32H balances optimum film thickness at elevated temperatures with sufficient fluidity under cold start conditions, facilitating effective circulation and lubrication. The oil’s dielectric strength supports motor insulation, and its low pour point (-46 °C) and minimal wax content guarantee functionality in low-temperature conditions typical of refrigeration cycles. These measurable specs reflect engineering rigor suited to industrial and commercial HVAC&R systems.
Robust Application Across Refrigeration and Air Conditioning Sectors
Qishanr QSL-32H serves a critical role in both initial fills and maintenance service fills in diverse refrigeration systems, including new installations and equipment retrofits upgrading from mineral oils to poe refrigeration oil for enhanced compatibility. It satisfies OEM cross-reference requirements and is validated for use in hermetic and semi-hermetic compressors, enabling consistent system efficiency and defending against wear during continuous operation. This lubricant thus substantiates its value proposition by ensuring energy-efficient performance and lower total cost of ownership in industrial refrigeration, commercial air conditioning, and transport cooling systems.

OEM-Compliant Initial Fill for New Installation Projects
Within new HVAC&R equipment installations, operational efficiency and long-term reliability hinge on selecting compliant lubricants. QSL-32H from Qishanr, a premier refrigeration oil manufacturer, is specified as the initial fill oil to ensure proper chemical and thermal compatibility with screw, centrifugal, and scroll compressors using HFC refrigerants. The lubricant’s technical parameters—such as viscosity indices and dielectric strength—align closely with system requirements, enabling correct oil circulation and electrical insulation while supporting extended service intervals. This supports smooth commissioning and ongoing system performance under rigorous operational demands.
Yes, we offer QSL-32H as an ideal refrigeration compressor oil for initial fills in new systems as well as service fills during preventative maintenance. It meets OEM specifications and cross-references readily with other oils, supporting smooth transitions and long service life in both new and existing refrigeration equipment.
Because QSL-32H is hygroscopic, proper moisture control is critical to preserve oil performance and system reliability. We recommend strict handling procedures and moisture monitoring during storage, filling, and operation to maintain oil integrity and prevent system contamination in refrigeration and air conditioning compressors.
Yes, we provide technical guidance to select the optimal refrigeration oil based on compressor type—screw, scroll, centrifugal, or reciprocating—and refrigerant compatibility. Our expertise ensures you get a lubricant with the right viscosity and chemical properties to meet your system’s operational requirements efficiently.
