Tecogen Receives 1,200-Ton Clean Cooling Chiller Order for Cannabis Cultivation Facility

Contract is the 23rd cannabis-related project awarded to the Waltham MA-based manufacturer. Three 400-ton chillers will reduce energy need by 750 kW of electric capacity.


WALTHAM, MA, Sept. 14, 2021 -- Tecogen Inc. (OTCQX: TGEN), a clean energy company providing ultra-efficient and clean on-site power, heating, and cooling equipment, has received an order for three 400-ton Tecochill® chillers for an indoor cannabis cultivation facility in Massachusetts. This is the 23rd cannabis cultivation facility to select the Tecochill solution and will eliminate the need for approximately 750 kW of electric capacity if electric chillers were used. The chillers are expected be serviced out of Tecogen’s Waltham service headquarters.  

“We worked with the customer and their design team to ensure they could meet their cooling requirements given the limited electrical capacity at the location,” noted Stephen Lafaille, Tecogen VP of Business Development.  “Since they are a vertically integrated provider, additional power and cooling was needed for the post-cultivation processing and extraction.  By eliminating the additional electrical capacity needed for cooling and dehumidifying the facility, they can use their limited capacity for other operations.”

Many cannabis cultivation companies integrate cultivation, processing, packaging, delivery, and sales at one location, but have limited electrical capacity for all process operations. By selecting clean gas cooling with Tecochill, these customers can avoid expensive or prolonged electrical infrastructure upgrades needed to meet the added power requirements, thus saving them from making significant investments in additional capacity or facing lost revenue as they await electrical upgrades.  

“To date, the amount of clean cooling we have sold to indoor cannabis cultivation facilities represents approximately 7.5 megawatts of electric capacity generated cleaner and more economically than the grid,” stated Benjamin Locke, Tecogen’s CEO.  “This allows grow facilities to focus their available electric service on other critical processes and reduces the amount of backup generation needed to keep the facility operational during an outage; cleaner, more economical, and resilient -- that is Tecogen’s recipe for growth.
