Unmatched ammonia refrigeration lubricantEnhanced versions of the technology used by most OEMs, Rawls Equipment Company’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.

NXT 717 has an exceptionally low pour point for enhanced cold-temperature performance. Variations of NXT 717 include food-grade NXT 717-FG, extreme-low pour point 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•

NXT 717 utilizes high quality base fluids and additives to provide excellent low-temperature fluidity - providing distinct advantages over competitive formulations. Lower viscosities at evaporator temperatures help ensure the lubricant remains mobile, preventing clogging and build-up inside narrow heat exchanger passages. Combined with the low carryover potential of the formulation, NXT 717 helps to maintain, or improve, system efficiency by controlling evaporator contamination at the source - the lubricant.
