Bristol is introducing the H21J, its next generation Benchmark reciprocating compressor. According to the company, the new Benchmark H21J Recip requires no starting components, an innovation that improves reliability and provides a strong boost in SEER performance. It is specifically designed to optimize the performance of air conditioning systems rated 13 SEER and above. And, the company says, the new compressor is noticeably quieter than competitive units in system sound testing - by 1.5 dBA.
