We respectfully announce the retirement of one of Hansen’s most dedicated and long-term contributors – John Yencho. John has been a key contributor to our success over his 34+ years of service and the industry. Although he is officially retiring, we expect him to remain involved with Hansen’s on-going innovation efforts.

John has shared his time and technical expertise with industry through his many years of involvement with IIAR – as a Board member, committee member (Standards and Co2) and as a technical presenter. He has also presented at various international conferences and industry associations.

For those who do not know John as well, he began his journey with Hansen Technologies in July of 1984, almost at its conception. He was instrumental in developing many of the valves and technical equipment that we are still building today. John’s most recognizable accomplishment was designing and helping introduce the Auto-Purger, which makes refrigeration systems more efficient by removing air and other noncondensible gas.

We will be honoring John by dedicating our headquarters in Burr Ridge, Illinois, as the “John A. Yencho – Innovation Center”.
