NXT-4225 is a high-performance lubricant that combines specially blended polyol ester (POE) refrigeration lubricants and other synthetic base fluids. This advanced formulation provides superior protection in HFC refrigeration systems, exceptional chemical and thermal stability and a long service life.

Using NXT-4225 offers the following benefits:

Long-lasting lubrication, protection and energy efficiency for a system that works without compromise — NXT-4225 is designed with a balanced approach that provides sufficient oil return without compromising the wear-protection capabilities of the lubricant. Its high surface tension helps reduce carryover (oil loss). It also helps ensure proper oil return to the compressor, preserving thermal efficiency by preventing lubricant from accumulating in the system and building film in the evaporator.

Fewer fluid change-outs, better protection against wear and corrosion — Excessive water contamination often results in decreased bearing life, corrosion of components and premature fluid change-outs. Through its specially selected base fluids, NXT-4225 offers enhanced resistance against water contamination, thereby reducing the risk of rust and corrosion, minimizing wear (related to water diminishing the fluid’s ability to lubricate) and preventing the formation of system-blocking ice. Most competitive POE compressor fluids are highly susceptible to water contamination.

Better system efficiency through enhanced cold-temperature fluidity — NXT-4225’s excellent low-temperature fluidity ensures proper lubricant return, preserving thermal efficiency by preventing lubricant from accumulating in the system and building film in the evaporator.

Excellent rust and corrosion protection for your system’s components — NXT-4225 contains advanced additives that protect against metal-induced oxidation and copper corrosion. This helps keep your system in good working condition longer.
