NRM Success Story
Aeronaut Brewing
Somerville, MA
Aeronaut Brewing has slashed their electric bill by roughly $2,600 per year. In the 5 years they've had NRM’s solution, they've recouped roughly $13,000 in profits that otherwise would've been spent on energy use.
Aeronaut Brewing Co. was on the hunt for a product or service that would allow them to monitor the temperatures of their various cold rooms, as well as provide them alerts if any of the spaces fell out of range. In their facility, they had four of these spaces: a keg cooler, a hops cooler, a foods freezer, and a packaged-product cooler. Each had their own temperature requirements, and the staff became overwhelmed constantly checking to ensure all of the cold rooms were cooled to where they needed to be on top of their normal, daily work obligations.
For their varied range of beers, precise temperatures were critical because a change in temperature affected the brewing cycles and thus affected what they can sell and when.
As for the alerts, Aeronaut Brewing Co. needed a means of avoiding a catastrophic failure in their equipment. They’d lost a compressor before, and the disruption to their brewing cycles wasn’t something they could afford to suffer through again.
NRM was able to provide a custom solution that went above and beyond what Aeronaut Brewing Co. had originally sought. All of the cold rooms were retrofitted with on-site controls, and connected to the Remote Site Manager monitoring platform, which both automated temperature logging and provided real-time alerts for a range of factors that could affect their temps: things like doors being left open, iced up evaporator coils, and compressor short cycling.
Remote Site Manager allowed the staff to track and compare temperature performances from anywhere, anytime, through the platform’s online dashboard. On top of the four cold rooms, Aeronaut Brewing Co. was able to monitor the performance of their chiller and their glycol.
The optimizations NRM performed also made each cooling system more energy efficient. By automating temperature settings, defrost cycles, and bringing to light issues that waste energy, Aeronaut Brewing Co. will see a projected annual savings of 17,400 kWh.
NRM was also able to procure a 50% energy efficiency incentive through their local utility.

"The monitoring and the alarm system were why we decided to buy. In our environment, even going one day with an issue that no one notices can throw off entire brewing cycles. This can directly affect what we can sell and when, which impacts our bottom line. We also wanted to avoid a catastrophic failure; we’ve lost a compressor before and it was an expensive fix. The energy savings were an added bonus."
