Premium Ammonia Refrigeration Compressor Lubricant

Your Optimal Solution for Ammonia
Refrigeration Compressor Lubrication

Unmatched ammonia refrigeration lubricant

Enhanced versions of the technology used by most OEMs, KOLDIN NXT’s ammonia refrigeration line represents the next generation of 2-stage hydrocracked ammonia refrigeration lubricants. They are specifically formulated tp provide the highest level of performance and protection possible. This has been achieved through our detailed knowledge of ammonia refrigeration system and more than two decades of experience in advanced ammonia refrigeration lubricants. ROLDIN NXT 717 has an exceptionally low pour point for enhanced pold – temperature performance. Variations of KNXT 717 include food grade KNXT 717-FG, extreme-low pour point KNXT 717-XLT, and seal -conditioning KNXT 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

Low Temperature Fluidity Properties

KOLDIN 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, KOLDIN NXT 717 helps to maintain, or improve, system efficiency by controlling evaporator
contamination at the source – the lubricant.
