Harpoon selected A/Z to help implement a combined heat and power (CHP) solution for its Boston, MA brewery. A new 250 kW natural gas-fired generator was installed at the site and tied into the facility alongside Harpoon’s ongoing manufacturing operations. The new process piping and heat exchanger that were integrated by the team allows exhaust heat from the generator to be used in Harpoon’s manufacturing operations for hot process water. This results in an overall efficiency of more than 90%. The new CHP system is generating energy that covers 70% of the brewery’s electrical needs and 90% of its hot water demands.
