Kirin Beer Hokkaido Chitose Factory

Improvement of energy saving and work environment

They produce the Kirin’s flagship brands such as the Ichiban Shibori and the Lager, and are a manufacturing base for the Hokkaido region. The expansive factory is surrounded by greenery and regularly hosts events. They also offer factory tours that allow visitors to see their production facility up close (reservation required). It is a popular spot not only for families, but also for local residents as an “adult social tour”.

Reason for Selection

Heat generation for essential wheat and rice preparation process
Expectation of energy savings and other benefits

Every year, we have taken energy-saving measures for steam boilers, which are the heat generation equipment for boiling wheat and rice, the raw materials for beer. NTEC proposed the “F-nex” system as one of these energy-saving measures. When we heard from them that this system could recover the hot air in the boiler room and use it as thermal energy, we immediately reached a consensus within our company and decided to adopt it. As a result, the energy savings and improvement of the working environment in the boiler room exceeded our expectations. We were also reassured by their prompt response and are impressed by their speedy and accurate proposals as they actually survey the site.

NTEC’s Proposal

Feedwater preheating
system

Energy savings and additional improvement by heating feedwater with high-efficiency heat pump

The boiler room was as hot as a sauna. We proposed the “F-nex” system to them, which uses a heat pump to recover the hot air and raise the boiler feed water temperature. As a result, the boiler room temperature has been lowered by effectively recovering the heat and their working environment has been improved.

Effects

Improved system efficiency through effective hot air recovery reduces fuel costs and CO2 emissions, and lowers the boiler room temperature, improving the working environment.
