Unmatched ammonia refrigeration lubricantEnhanced versions of the technology used by most OEMs, NXT’s ammonia refrigeration line represents the next generation of 2-stage hydrocracked ammonia refrigeration lubricants. They are specifically formulated to provide the highest level of performance and protection possible. This has been achieved through our detailed knowledge of ammonia refrigeration systems and more than two decades of experience manufacturing advanced ammonia refrigeration lubricants.

NXT 717 has an exceptionally low pour point for enhanced cold-temperature performance. Variations of NXT 717 include food-grade NXT 717-FG, lower and extreme-low pour point options NXT 717-LT and NXT 717-XLT, and seal-conditioning NXT 717-SC. These lubricants all offer:

Extremely low volatility and solubility • in ammonia systems to reduce oil carryover

Advanced, industry-leading cold-temperature • fluidity and pour-point technology to maintain pumpability, even under extremely low-temperature conditions

Enhanced oxidative stability, helping to reduce • oil loss and extend oil life

System protectants to help control and prevent rust and corrosion•
