I. For Data Center WSC Centrifugal Chillers (R134A Refrigerant)

Pain Point: Low-temperature shutdowns
Solution: Oil A

• Pour point as low as -46℃: Maintains smooth fluidity even when data center night temps drop below 0℃, no more sudden stops.

• Viscosity 32.5 cSt at 40℃: Forms a stable oil film on steel-aluminum parts, matching the unit’s 100,000-hour lifespan design.

• Cost Benefit: Cuts disassembly maintenance by 2x/year, saving nearly 10,000 yuan in labor costs annually.

II. For Commercial Building WHS Screw Chillers (R22 Refrigerant)

Pain Point: Oil deterioration & pipe clogs
Solution: Oil C

• Acid value < 0.05 mgKOH/g: Slows oxidation despite frequent start-stops, extending oil change intervals from 3 to 9 months.

• Strong thermal stability: Prevents sludge buildup, fully avoiding AC outages caused by pipe blockages.

• Revenue Protection: Reduces losses from customer churn due to sudden air conditioning failures.

III. For Eco-Friendly PFSV Units (R410A Refrigerant)

Pain Point: Falling energy efficiency
Solution: Oil E

• High compatibility with R410A: No oil-refrigerant separation, lowering friction loss and matching the unit’s ≥6.3 energy efficiency rating.

• Energy Saving: Cuts monthly electricity costs by at least 15%.

• Durability Boost: Reduces compressor wear, dropping unit failure rates by 40% for uninterrupted operations.
