I. Daphne Resolves Daily Cooling Troubles
Daily cooling issues often stem from underperforming refrigeration oil, such as:
✅ Loud noise and high electricity bills from air conditioners in summer
✅ Slow cooling of refrigerators in winter
✅ Unpleasant odors from car air conditioning systems
Traditional refrigeration oil has obvious drawbacks:
❌ Tends to solidify at low temperatures
❌ Deteriorates easily at high temperatures
❌ May be incompatible with eco-friendly refrigerants, shortening equipment lifespan
As a trusted product under Idemitsu, Daphne Refrigeration Oil offers tailored solutions for household scenarios with common models:
-
FVC68D: Specialized for household air conditioners
- FVC32D: Ideal for household/commercial refrigerators
- R134a-compatible models: Designed for car air conditioning systems

Market Position: A best-selling original-equipment-level oil, compatible with Hitachi, Daikin, and other top air conditioner brands.
▶ Base Oil: Polyvinyl ether (PVE) synthetic, ensuring compatibility with R410A/R407C refrigerants (no oil return issues).
▶ Low-Temperature Performance: Pour point of -37.5℃, enabling smooth heating startup in northern winters.
▶ Efficiency & Quietness: Kinematic viscosity of 66.6mm²/s at 40℃ (forms stable oil film, reduces wear noise, and cuts electricity costs).
2. Household/Commercial Refrigerators: FVC32D
-
Availability: Readily available online, suitable for refrigerators/freezers using R404A refrigerant.
▶ Anti-Hydrolysis: Ether-based base oil prevents sludge formation (avoids pipeline clogs).

▶ Practical Benefits: Accelerates cooling speed and extends food freshness.
3. Car Air Conditioning Systems: R134a-Compatible Models
-
Core Material: PAG base oil (excellent high-temperature oxidation resistance, flash point > 200℃).
▶ Odor Solution: Inhibits rust and sludge to eliminate unpleasant smells.
▶ Performance Boost: Speeds up cooling and extends compressor lifespan by over 3 years.
III. Key Points for Selection and Use
