Bristol Compressors International Inc. said it is working on making spool machine technology from Torad Engineering LLC applicable to residential and light-commercial air-conditioning systems.

A team from Bristol and Torad have been working on the project and hope to have a prototype ready for testing soon, officials said.

“Bristol Compressors is taking a leadership role in the development and commercialization of this exciting new compressor technology,” said the company’s CEO and president, Ed Gniewek. “We believe the spool compressor’s attractive cost structure and operating characteristics will be a game changer for our customers.”

Torad’s spool compressor technology uses a rotary design with four main components: rotor, main housing, vane and bearing housing. Officials with Torad and Bristol say that unlike scroll and screw compressors, they can be made less expensively for large projects.

“In my 20 years of experience in the compressor industry, I have never seen a concept go from design to prototype in such a short period of time” said Joe Orosz, president of Torad Engineering. “It is a testament to the excellent engineering team at Bristol and simplicity of the spool machine.”
