Lubricant with Seal Conditioner

NXT 717-SC a seal-conditioning formulation from among our group of products representing the next generation of 2-stage hydrocracked 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 better pumpability even under extremely low-temperature conditions. This oil helps stop and prevent leaks by conditioning and restoring hardened seals, O-rings and elastomers. NXT 717-SC is also completely top-off compatible with most normal paraffinics, naphthenics, alkylbenzenes, PAOs, and single-stage hydrocracked products.

Performance Advantages

  • Specifically designed for use in ammonia refrigeration compressors
  • Protects against rust, corrosion, carbon and varnish
  • Low solubility with ammonia
  • Conditions and restores hardened seals, O-rings and elastomers to help stop and prevent leaks
  • 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
  • Pour point enhanced as a result of the addition of proprietary additives
  • Non-toxic and non-hazardous
  • Low volatility, resulting in less carryover to evaporators
  • High flash and auto-ignition points for added safety
  • Thermal and oxidative stability promote longer fluid life and extended oil-drain intervals
  • Excellent film strength and anti-wear properties for better protection of compressor parts
