Product Overview
PRODUCT INTRODUCTION
The Solest synthetic refrigeration oil series is the first polyol ester (POE)‑based synthetic refrigeration oil developed in the United States, specifically designed for compressors using environmentally friendly refrigerants (HFCs). It is engineered for factory‑initial filling in the air‑conditioning and refrigeration equipment industries, as well as for after‑sales service and maintenance by original equipment manufacturers (OEMs). CPI’s laboratory has conducted extensive bench‑test evaluations of OEM‑specific compressor platforms, resulting in a portfolio of specially formulated products that fully meet system requirements, are non‑toxic, and comply with U.S. standard 29 CFR 1910.1200. CPI delivers enhanced performance—far surpassing conventional mineral oils—in terms of viscosity index, flash point, fire point, and pour point.
