Product details
Danfoss 320SZ POE Lubricant | 1 Liter | 120Z0572
Product Description:
The 320SZ lubricant (120Z0572) is a high-viscosity POE oil designed to provide superior protection for heavy-duty HVAC and refrigeration systems. In the UAE, where large commercial chillers and industrial cooling units face extreme operating pressures and temperatures, the 320SZ grade ensures a robust lubricating film. It is highly miscible with HFC refrigerants like R407C, R134a, and R404A, ensuring that oil circulates efficiently back to the compressor even in complex piping networks found in Dubai’s high-rise buildings. This 1-liter container is perfect for precise top-ups or specific maintenance tasks where the highest level of chemical stability and wear protection is required for Danfoss equipment.
Key Features & Benefits:
- High-Viscosity Performance: Specifically designed for larger compressor frames used in UAE commercial cooling, providing enhanced bearing and scroll protection.
- Superior Oil Return: Maintains excellent flow characteristics with HFC refrigerants, preventing oil trapping and maintaining evaporator efficiency in UAE heat.
- Thermal & Chemical Stability: Resists breakdown at high discharge temperatures, reducing the risk of carbon deposits and system contamination.
- HFC Compatibility: Optimized for R407C and R134a, the standard refrigerants for many commercial HVAC installations in Dubai and Abu Dhabi.
- Moisture Resistance (When Sealed): Formulated to maintain purity and protect internal system components from corrosion and wear.

FAQs:
- Q: Can I use 320SZ (120Z0572) instead of 160SZ in my UAE system?
- A: No. You must use the specific viscosity grade (e.g., 320SZ vs 160SZ) recommended on the compressor’s nameplate to ensure proper lubrication and internal clearances.
- Q: How should I handle this oil in the humid Dubai environment?
- A: POE oil absorbs moisture rapidly. Keep the container sealed until the moment of use, and always perform oil changes as quickly as possible to minimize exposure to UAE humidity.
- Q: Is this oil suitable for the new low-GWP refrigerants?
- A: While POE is generally compatible with many newer blends, always check the latest Danfoss compatibility chart for your specific UAE project requirements.
