Bristol Compressors and DHX Electric Machines Develop Next Gen Compressor Motors

bristol compressors international, llc and dhx electric machines, inc. announced an exclusive global strategic partnership to develop next gen hvac/r compressor technology leveraged by ultra-high torque density electric motors with patented micro-feature enhanced direct winding heat exchanger dwhx cooling system.


through this partnership, bristoland dhx will develop and deliver the most cost effective high efficiency compressors and systems in the industry.


dwhx™ is the future of hvac/r compressor motor technology. the dwhx™ cooling system targets the main source of heat by placing the micro cooling flow channel adjacent to the windings in the center of the slot-- increasing the surface area and local fluid velocities leading to a 25x improvement in cooling capability over standard flow channels.


"the dwhx™ patented motor technology will allow bristol to develop compressors that are shorter in height and lighter in weight than anything on the market today. furthermore, we will do all of this with 'best in class' efficiency levels across the board. our customers and their system designers will now have more space design options with improved system efficiency at the lowest applied cost," says kevin mumpower, vice president of product engineering, bristol compressors.


"we believe that this new motor technology is poised to significantly improve cost/performance ratio, add system design flexibility, as well as enable short and long-term regulatory system compliance. this will fundamentally change the hvac/r industry's expectations of compressor performance," says luka lojk, vp sales and marketing, bristol compressors.


dr. j. rhett mayor, president & ceo of dhx electric machines, inc. added that "dhx looks forward to partnering with bristol and we're excited to see the years of r&d on the dwhx™ cooling system evolving into a disruptive technology offering in the hvac/r market."
