OIL This oil is very best lubricating. The Lubricant is a all-temperature blend that is designed to increase efficiency, reduce wear and prevent carbon building. It performs four times longer than petroleum-based lubricants. Key Features and Benefits Long Life / Extended Runtime Ultra Coolant is rated for up to 8, 000 hours of run time under normal conditions. ingersollrand.com +2 Air Compressor Services +2 This helps reduce maintenance frequency and costs. Sellco Bangladesh Ltd Thermal Stability & Cooling Performance Very good at managing heat — its formulation gives it high thermal conductivity, helping dissipate heat effectively. ingersollrand.com Operating temperature range (per some specs) is about 15 °C to 60 °C. compressoroil.in +1 Low Foaming / Low Carryover Ultra Coolant has non-foaming performance, which lowers “carryover.” Carryover here means how much of the oil is carried out of the compressor in the gas stream, which can lead to contamination. ingersollrand.com According to suppliers, carryover is much lower (~75% less) than with mineral oils or some other synthetics. Sellco Bangladesh Ltd Safety / Stability Flash point is high: for the 5 L pack (part 92692284), flash point is around 238°C. compressoroil.in +1 Pour point (lowest temp it flows) is very low: around –45 °C for the 20 L part. compressoroil.in According to its MSDS, it’s formulated from a blend (polyoxyalkylene glycol + pentaerythritol ester), and has low volatility. irtechpubs.com Efficiency / Environmental Impact Better compressor efficiency due to effective cooling and lubrication. ingersollrand.com Longer life means less frequent disposal, which can reduce environmental impact. Sellco Bangladesh Ltd Compatibility & Usage Recommended by Ingersoll Rand for their “contact-cooled” rotary screw compressors. ingersollrand.com +1 According to maintenance guides, change interval is typically every 8, 000 hours or every two years, whichever comes first. portlandcompressor.com Trade-offs / Considerations Cost: Synthetic coolants like Ultra Coolant are more expensive than conventional mineral oils, but the extended life and performance benefits often justify the cost. Disposal / Handling: As a synthetic glycol-based fluid, proper disposal is required. Always follow local regulations. Mixing: You should avoid mixing different types of compressor oils/coolants. Using the correct type (manufacturer-recommended) is important for performance and reliability.
