COOL-PLUS PAO ULP 68 is an ISO VG 68 grade, ultra-low pour point synthetic refrigeration compressor lubricant formulated from highly refined polyalphaolefin (PAO) chemistry. It is specifically engineered for extreme low-temperature industrial refrigeration and flash-freezing applications operating with ammonia, carbon dioxide, or hydrocarbon refrigerants. The "ULP" designation highlights its specialized wax-free composition, which provides an exceptionally low pour point and outstanding fluid mobility at temperatures where standard oils thick or gel. This fluid features excellent thermal and oxidative stability, preventing oil breakdown and viscosity changes under high discharge temperatures and continuous heavy loads. Its superior shear stability and high viscosity index deliver optimal wear protection for critical compressor components, significantly reducing mechanical friction. Additionally, the advanced formulation exhibits highly efficient oil separation and superior resistance to varnish, sludge, and carbon deposit formation, keeping internal valves and evaporator coils exceptionally clean. Ultimately, this clean-running, low-temperature specialist fluid ensures reliable oil return, minimizes system maintenance downtime, and extends the operational lifespan of demanding industrial compressor systems.
