Miscible Carbon Dioxide Refrigeration Compressor Lubricant
NXT 744-POE
(Former 6227)
Isel 6227 becomes NXT 744-POE.
NXT 744-POE is formulated specifically for use in carbon dioxide refrigeration systems. Its advanced formulation provides superior miscibility and lubricity in high-pressure carbon dioxide systems. NXT 744-POE also offers excellent chemical and thermal stability, low-temperature fluidity and a very long service life.
Attributes
- Optimized miscibility with carbon dioxide refrigerants
- Controls carbon and varnish to help reduce deposits
- Excellent film strength and anti-wear properties
- Long fluid life, allowing for extended oil-drain intervals
- Controls rust and corrosion for enhanced component protection
- High flash and auto-ignition points for added safety
- Low volatility
- Non-toxic/non-hazardous
- High viscosity index for better compressor protection at elevated temperatures
- Superior thermal and oxidation stability and long life in carbon dioxide systems
