The ‘HOOPS' here is Hot Oil Over Protector, a proprietary technology designed to minimize the time it takes to detect a thermal fault condition and react to it in order to protect a compressor.
"HOOP technology is something entirely new," said Rick Izor, executive vice president for Bristol Compressors, which has developed the technology for Benchmark scroll compressors. "Rather than relying on hot gas, HOOP uses hot oil to quickly trip the motor protector and protect against a compressor failure."
