John Siegenthaler Presented Carlson-Holohan Industry Award of Excellence


At the recent AHR Expo in New York City, Caleffi was pleased to host the ceremony for honoring industry hydronics expert John Siegenthaler of Appropriate Designs.  Robert Bean, Dan Holohan, David Yates, Mark Eatherton and John Barba, previous winners of the award, were on hand to present the Carlson-Holohan Industry Award of Excellence to John.

In the spirit of Gil Carlson and the benevolence of Dan Holohan the award came into existence.  Every two years, an individual who has demonstrated their passion for hydronic technologies manifested through education, marketing and fund raising are presented with the original Bell & Gossett sizing wheel invented by Mr. Carlson.

We extend a sincere congratulations to John from all of us at Caleffi.
