Better, More Efficient Ammonia Systems

The NXT 717 family represents the next generation of 2-stage hydrocracked lubricants. Every NXT ammonia lubricant takes into consideration the operating conditions of the facility, the refrigerant-lubricant interaction in the system, the estimated energy savings the lubricant can provide and numerous other factors.

 

NXT 717 Lubricants

 

Increased Low-Temperature Fluidity & Improved Energy Savings
NXT ammonia compressor lubricants remain mobile at extreme cold temperatures, preventing clogging and build-up inside narrow evaporator passages.

Facilities running the NXT 717 family of lubricants have saved thousands of dollars annually in energy savings when switching from leading competitive lubricants.

The combination of lower solubility with ammonia, reduced carryover, and better pumpability results in significantly greater evaporator efficiency.

 

Reduced Oil Carryover to Evaporators, Extended Fluid Life & Protection
Extremely low volatility and solubility in ammonia systems ensures that NXT 717 reduces oil carryover. This causes the evaporator to operate more efficiently and at a higher capacity.

The enhanced oxidative stability of NXT 717 helps to extend oil life. The advanced additive package controls and prevents corrosion of system components.

Customers running NXT 717 have seen upwards of 72% reduction in annual oil use.1

                  Carbon Dioxide Products

                  Isel’s carbon dioxide refrigeration compressor lubricants are formulated for superior system protection, with miscible and immiscible varieties engineered to accommodate a range of system designs. Both varieties are formulated to:

                  • Ensure appropriate refrigerant/lubricant solubility
                  • Promote oil return

                  The immiscible formulation also meets H1 requirements for lubricants with incidental food contact, making it suitable for use in many food-industry applications.


                  NXT 744-FG (Former 2884)

                  Food-grade lubricant providing low-temperature fluidity and superior lubrication


                    NXT 744-POE (Former 6227)

                    Provides superb lubricity and low-temperature fluidity in high-pressure systems
