Integral Sciences Incorporated is engaged in Part 2 of ARTI Contract No. 660-52502 assessing methods for removing residual mineral oil during retrofits of refrigeration systems. Part 2 focuses on a low side oil separator technique for removing mineral oil from systems being retrofitted to use HFC-134a. The method appears less expensive than the current practice of three lubricant changes with polyolester and may effect an accelerated transition to HFC`s. Testing and method verification has been performed using a refrigeration system located at ISI`s facility. Two HFC-134a field retrofits employing this method will be implemented during the first quarter of 1995. A third and final field retrofit will also be performed to evaluate the advanced method in an R-502 conversion
