Boston Commercial Building Doubles Cooling Efficiency with Two RT-50 Tecochill Units

WALTHAM, MA -- (Marketwired) -- 07/27/17 -- 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 two Tecochill "RT-Series" 50-ton chillers to an office building in Boston, MA. The units will enable the building to reduce its annual cooling-related energy costs by well over 50% through the avoidance of costly demand charges. The result is a simple payback period for the customer of less than four years. This is before the possible consideration of any form of government rebate or credit.

Tecogen Product Manager Stephen Lafaille stated, "The air-cooled RT-Series chillers provide smaller commercial buildings with a powerful way to save on their cooling bills. The variable speed operation capability of all of our Tecochill products optimizes efficiency by enabling the units to adjust in real time to a facility's cooling needs."

"The electrical infrastructure in the city of Boston is unique due to its complex network of spot and radial networks. This makes traditional electrical CHP systems difficult to deploy in most areas of the city," added Benjamin Locke, Co-CEO. "The TecoChill product is a mechanical CHP system, which provides all of the same benefits of traditional electrical CHP systems but without the restrictions associated with electrical interconnection regulations."
