CHICAGO - Bristol Compressors is unveiling its new Benchmark "HOOP" technology for scroll compressors.

With HOOP, a Benchmark Scroll protects against thermal fault conditions, like loss of charge, much more quickly. Other compressors use hot gas to trip the motor protector, but HOOP uses hot oil, which is much quicker, says the company.

A faster response means less risk of compressor failure. Reliability goes up, while applied cost goes down, says Bristol.
