ATIGROUP co-founder Michael A. Bunting has been selected as one of five winners for the 2014 Michigan Small Business Awards. Bunting was awarded the Michigan Veteran Small Business Owner award during the 10th annual Michigan Celebrates Small Business awards event at the Breslin Center in East Lansing, MI on May 6th, 2014.

Bunting was the co-founder of ATIGROUP in 1986. Prior to founding ATIGROUP, Bunting served time in the United States Navy where he studied Steam Propulsion Engineering and air conditioning, heating and refrigeration from 1970-72.

Bunting and the other four award winners were selected based on their staying power, financial performance, contributions to the community and their work ethic with a small business.

Oil-Free, Magnetic Bearing, Chillers

Contrary to popular belief chiller plants are now the most efficient operating at partial load and the new technology of the oil free, magnetic bearing chillers are here to prove it.  We live in a region where our climates hit peak demand less than 10% of the time. Therefore, why would engineers design for the most efficient operation to occur when the chiller is loaded at 100% or at peak demand?   

With facilities mechanical systems operating at partial load over 85% of the time the magnetic bearing compressors are achieving a KWH savings of over 30% by performing at their “sweet spot” which is around 50% loaded.  The oil free chiller also dramatically reduces maintenance and operational costs by eliminating all the oil in the traditional chiller system. The concept that chiller systems are operating without any oil is almost unheard of and defies what mechanical service companies across the world understand.   The chiller operations is also so quiet the refrigerant flowing through the chiller is actually louder than the compressor running. 

This technology is sweeping across the country and has been in North America for over 10 years.  ATIGROUP was the first engineering firm to specify the Smardt Chiller in the Mid-West and Burcham Hill’s Retirement Community was the first leader in the industry to purchase this technology.
