Danfoss 175PZ PVE Lubricant | 1 Liter | 120Z0638

Product Description: The 175PZ lubricant (120Z0638) is the specialized oil required for many Danfoss scroll compressors operating across the UAE. Unlike traditional POE oils, this PVE lubricant is uniquely designed to be non-hydrolytic, meaning it does not react with moisture to form harmful acids. This characteristic is particularly beneficial in the UAE’s humid coastal environments, such as Dubai and Abu Dhabi, where moisture ingress during maintenance can be a challenge. It provides exceptional lubricity, chemical stability, and superior oil return properties, ensuring the smooth operation and long-term reliability of commercial and residential HVAC units in high-ambient temperatures.

Key Features & Benefits:

• Non-Hydrolytic Formula: Does not form acid in the presence of moisture, offering superior protection for UAE HVAC systems compared to POE oils.
• Optimized for HFCs: Perfectly compatible with R410A, R407C, and R134a, which are the primary refrigerants used in UAE cooling infrastructure.
• High Thermal Stability: Maintains its lubricating properties even under the extreme discharge temperatures common during the UAE summer.
• Excellent Oil Return: Ensures that oil circulates effectively back to the compressor, preventing mechanical wear and system inefficiency.
• Corrosion Resistance: Protects internal compressor components from wear and corrosion, extending the service life of equipment in the Middle East.

FAQs:

• Q: Can I mix 175PZ (120Z0638) with standard POE oil in a UAE system?
• A: No. PVE and POE oils should not be mixed. Always use the specific lubricant type recommended on the Danfoss compressor nameplate.
• Q: Why is PVE oil preferred for Dubai’s humid climate?
• A: Because PVE oil does not undergo hydrolysis, it eliminates the risk of acid formation if small amounts of moisture enter the system during servicing in humid UAE conditions.
• Q: Is this 1-liter bottle sufficient for a standard compressor oil change?
• A: It depends on the compressor model. Check the specific oil charge requirements in the Danfoss technical manual for your unit.
