Summit RTC Series employs a unique base fluid that provides optimum refrigerant solubility/miscibility. Other benefits of Summit RTC Series vs traditional POEs for refrigeration include:
• 50% less hygroscopic
• Less compressor component wear
• Less issues with copper plating
• Greater cooling efficiency
Summit RTC Series lubricants are designed exclusively for semihermetic (piston) refrigeration compressors requiring a POE-type lubricant for improved miscibility with the refrigerant and improved oil return to the compressor. These compressors, with relatively small oil capacities in the 1-5 gallon range, are used in many supermarket applications and commercial (mobile) refrigerated trailer/truck applications. Summit RTC Series is available in five viscosity grades for HCFC & HFC refrigerant gases like MO99, R22, R134a, R401a, R401b, R402a, R402b, R404a, R407a, R407c, R408a, R409a, R410a, R422a/d, R502, & R507c.
Mixing Summit RTC Series with other POE-based formulations should be avoided. There is no need to flush when converting to Summit RTC Series from other POE-based formulations. Always consult Summit engineers before using this product in other refrigeration applications.
