Alaska-based Denali Brewing and Spirits has completed the commissioning, site training and startup of its PROGreen CO2 (R744) chiller from U.S. manufacturer Pro Refrigeration; it is one of the first CO2 process cooling chillers installed in the U.S.
Plans for the installation at the brewery were first announced in May, following a year of research, development and engineering. The installation was done by Pro Refrigeration and Denali’s service contractor, Arctic Refrigeration. Additional remote support was provided by South African consultancy Future Green Now (FGN).
Pro Refrigeration’s 100 HP PROGreen CO2 chiller replaces Denali’s HFC-blend-based 40HP PROChiller System, also from Pro Refrigeration, which was installed in 2013.
This system provides up to 1,000,000 BTU/HR cooling capacity to support Denali Brewing Company’s new product line while also making use of onboard heat recovery to support the distillery’s building and water heating needs.
