Designed specifically for applications encountering extremely low-temperature operating conditions or atmospheric environments,

NXT 717-XLT represents the next generation of synthetic ammonia refrigeration lubricants. This lubricant is an enhanced version of the technology used by most OEMs. It offers reduced solubility with ammonia, less oil carryover and improved pumpability.

NXT 717-XLT is also completely top-off compatible with most normal paraffinics, naphthenics, alkylbenzenes, PAOs and single-stage hydrocracked products

Performance Advantages

  • Low solubility with ammonia
  • Specifically designed for use in ammonia refrigeration compressors
  • Protects against rust, corrosion, carbon and varnish
  • Thermal and oxidative stability promotes longer fluid life and extended oil-drain intervals
  • High viscosity index for superior pumpability at lower temperatures and better protection at high temperatures
  • Non-toxic and non-hazardous
  • Low volatility, resulting in less carryover to evaporators
  • High flash and auto-ignition points for added safety
  • Excellent film strength and anti-wear properties for better protection of compressor parts
