PermaCold Signature PC-717 Oil Offers Superior Performance at Lower Cost

Designed to meet and exceed all OEM specifications such as those seen in Frick #3, Frick #9, FES #1, among others; PC-717 is now the highest quality lubricant for ammonia refrigeration systems. By using a 2 staged hydrocracked process to remove all impurities normally seen in lower quality base stocks, combined with a specific additive package, PC-717 serves as an enhanced version of the oil recommended directly from the compressor manufacturers themselves.

PC-717 is ideally blended to meet our customer's specific operating conditions and technical requirements while providing the highest level of performance and protection possible. Formulated for superior low temperature fluidity, and a flash point of 480 F for added safety, PC-717 will reduce oil carry over and sludge build up correlating to a longer service life. Standing in as an enhanced version of the technology used by most OEM's, PermaCold Engineering's ammonia refrigeration line represents the next generation of 2-stage hydrocracked ammonia refrigeration lubricants. This has been achieved through our comprehensive knowledge of ammonia refrigeration systems and more than two decades of experience manufacturing advanced ammonia refrigeration lubricants.


PC-717 reduces oil consumption, and increases savings. This is accomplished by reducing the wear and tear on your compressor with superior lubrication to help cut utility costs and maximize savings. PermaCold Engineering's PC-717 is non-toxic/non-hazardous making it safe to work around. Not only will your compressor experience a longer fluid life, but PC-717 will also help prevent degradation by using system protectants to help prevent rust and corrosion. Less maintenance and repairs translates to maximum uptime and increased savings on parts and service. No more settling for less than exactly what you need, PC-717 extends the life of your compressor and your lubrication with enhanced oxidative stability, helping to reduce oil loss, extend oil life, and increase oil drain intervals. Simply put, PermaCold Engineering's PC-717 is built to last. See our full list of high-performance product attributes below...


Fluid Viscosity

The viscosity (measure of a fluid's resistance to flow) of PC-717 was designed to be low enough to flow where needed in a timely matter, but high enough to form and maintain a sufficient cushion between surfaces.


Very Low Volatility

High volatility lubricants tend to vaporize more rapidly, thus making it difficult for oil and ammonia to separate (which in turn increases oil carryover). PC-717 is a 2-staged hydrocracked oil that is designed for low volatility, reducing oil carry over, carbon and sludge build-up.


Ultra Low Solubility


Solubility indicates the maximum amount of lubricant that can be dissolved in ammonia. PC-717's low solubility is specifically designed to reduce make up oil & oil loss, while preserving lubricant viscosity to reduce friction, heat, and wear.


Top-Off Compatibility


PC-717 is compatible with NXT-717 and most Mineral and PAO fluids used with Ammonia Refrigeration. It can be mixed or topped off in any ratio.

Low Pour Point and Highest Flash Point for Added Safety

Standard PC-717 offers low-temperature fluidity & pumpability, helping to prevent slugging and maintain sufficient oil return. PC-717 offers an extremely high flash point (480 F) for added safety.

High Viscosity Index & Thermal Stability

Has excellent cold-temperature fluidity due to its high viscosity index (Resistance to thinning w/ increasing temperature). PC-717 is designed to maintain stability of molecule compounds at high temperatures w/ excellent thermal stability.


Oxidative Stability

Offers great resistance to oxidation with a fine rate of oxidation stability. Oxidation increases w/ time and is accelerated by high temperatures, water, acids, copper. PC-717's high quality base stocks combined with an additive package designed to avert oxidation.

No adverse effect on Shaft Seals, elastomers, and other internal components


PC-717 works great with seals, and elastomers. Pour base stocks will effect seals and have a higher vaporization. PC-717 uses the highest quality base stocks to combat this issue and even enhance the protection of shaft seals and other parts.
