Bulova Corporate Center Orders Four 200-ton Tecochill Units

WALTHAM, MA -- (Marketwired) -- 02/07/18 -- Tecogen ® Inc. (NASDAQ: TGEN), a clean energy company providing ultra-efficient, clean, natural gas powered on-site power, heating and cooling equipment, is pleased to announce the sale of four 200-ton Tecochill STx Series water-cooled chillers to the Bulova Corporate Center in Queens, NY. The chillers will replace five 170-ton Tecochill units installed in 1994, which were approaching the end of their service lives. The sale includes a long-term service contract and qualifies for incentives from Con Edison's Demand Management Program. D&B Engineering is providing the owner with turnkey services, including grant writing, and plans to install the equipment in February. Once these four chillers are in operation, Tecogen will have six Tecochill units servicing the building, including two 350-ton DT Series chillers that D&B installed in 2002.

Tecogen Vice President of Sales Jeffrey Glick said, "This is now our third installation with D&B at the Bulova Corporate Center. D&B has been a great partner for many years. We have worked with them on dozens of projects covering all of our products across New York and New Jersey. As commercial properties go, Bulova is an ideal fit for our chillers thanks to its ability to utilize the hot water our units produce."

Benjamin Locke, Tecogen's Co-CEO stated, "The chiller replacement cycle continues. The fact that customers are happy to do repeat business with us decades after an initial sale speaks volumes not only of the quality of our products and service, but also that the value proposition of our natural gas-powered chillers is real and unrivaled. Mechanical CHP, as we call it, works."

D&B Engineering has a long history working with Blumenfeld Development Group (BDG), the owner of the Bulova Corporate Center. "D&B has always been on the leading edge with HVAC technology and energy economics," according to D&B Engineering Senior Director of Business Development John Taguer. He continued, "We have been involved with several upgrades at Bulova and appreciate the faith BDG has placed in us. In turn, we have tremendous confidence in the quality and economic benefits that Tecogen's products bring to the table. It's a natural fit."

Anthony Roberts, Chief Engineer at Bulova, agreed, stating, "Choosing to work with D&B on this project was simple. The hardest decision was when to replace the chillers. They've been covered by a long-term service contact and, given the high level of service provided to the machines since their installation, they could last another decade. In the final analysis, upgrading to Tecogen's newest equipment now maximized our benefit. The installation of these super-efficient Tecochill chillers is expected to save BDG millions of dollars in energy costs and dramatically reduce emissions over their service lives."
