Danfoss 175PZ PVE Lubricant | 2.5 Liters | 120Z0639
Product Description: The 175PZ lubricant (120Z0639) is the professional choice for maintenance and first-fill applications in Danfoss scroll compressors. This 2.5-liter volume is ideal for UAE HVAC technicians servicing medium-to-large commercial units, such as chillers and rooftop packages in Dubai and Abu Dhabi. Unlike POE oils, PVE lubricants are non-hydrolytic, meaning they do not react with moisture to create acid. This provides a massive advantage in the UAE’s humid coastal regions, ensuring that any incidental moisture during a field service doesn’t compromise the system’s chemical integrity. It offers excellent solubility with R410A and R407C, ensuring efficient oil return and maximum compressor protection under the high thermal loads of the Middle East.
Key Features & Benefits:
- Acid-Free Moisture Management: Non-hydrolytic properties prevent the formation of sludge and acid, a common failure point in humid UAE environments.
- Superior Lubricity: Reduces internal friction and wear in high-speed scroll components, extending the life of compressors in Dubai’s heat.
- Enhanced Oil Return: Specifically formulated to travel effectively through the refrigeration circuit, preventing oil logging in evaporators.
- Optimal 2.5L Size: Designed for commercial-scale service, providing enough volume for complete oil changes in high-tonnage UAE cooling systems.
- Chemical Stability: Maintains its viscosity and performance even when exposed to high discharge temperatures typical of the UAE summer.

FAQs:
- Q: Is 175PZ (120Z0639) compatible with R22 systems in the UAE?A: This oil is primarily designed for HFCs. For R22 systems, mineral or alkylbenzene oils are typically used. Consult Danfoss technical support before switching.
- Q: Does this 2.5L bottle require special storage in the UAE heat?
- A: It should be stored in a cool, dry place. Once opened, it should be used quickly or sealed tightly, as PVE oil is hygroscopic (absorbs moisture), even though it doesn’t form acid.
- Q: Why use 175PZ instead of POE oil for Dubai projects?
- A: Reliability. PVE oil’s resistance to hydrolysis means fewer “acid burnouts” in commercial systems, which is a significant benefit for UAE property managers.
