cutting-edge solutions designed to maximize brewing
operations, promote energy efficiency and
cost-effectiveness.

In late 2015, Two Roads Brewing Company in Stratford, CT was
looking to expand its fast-growing brewery and needed the
expertise of a leading-edge HVAC/R manufacturer to assist them.
Phil Markowski, Master Brewer, and Mike Wight, Director of
Operations contacted a local HVAC contractor who put them in
touch with Gregg Mello in the Carrier Enterprise (CE)
Connecticut office, who heads up the region’s Craft Beer Cooling
division and is a knowledgeable and passionate craft-brewing
enthusiast. Combining Two Roads’ expansion needs, Mello’s craft
brewing expertise and Carrier’s specialized chiller equipment,
CE designed a cutting-edge system that would exceed Two Roads’
expectations.
Two Roads Brewing Company started their brewery in 2012 with an
80 HP chiller system installed in a building built in the 1920s
that was the former home of U.S. Baird Manufacturing Company, a
metal-forming machinery manufacturer. With its funky, retro vibe
and unique lifestyle philosophy Two Roads became very popular
right from the start and grew quickly. In late 2015, the company
realized their existing operation was at capacity, so they began
their first of two major expansions, taking them from being a
75,000 barrel a year operation to 150,000 barrels to be produced
for both Two Roads and other small craft beer artisans by the
end of 2017.

The process of heating
and cooling the wort, the liquid created in the beer brewing
process, is critical to the success of craft beer and it is crucial
that the chiller operates quickly and efficiently to lower the wort
back to the ideal temperature. With his in-depth knowledge and
passion for craft brewing, Gregg Mello worked closely with Markowski
and Wight and a local HVAC contractor to design a system that would
meet the goals of integrating the brewery’s existing chiller system,
be easy to install with little infrastructure upgrades, and would
offer the highest energy efficiency with the best return on
investment. After analyzing the current system and overall
operational goals, Mello turned to Carrier Corporation to find the
best chiller system that would provide non-ozone depleting
refrigerant, simple installation, superior energy efficiency and
powerful controls.
“It was important for the expansion to seamlessly integrate the
existing chiller into the new system with minimal infrastructure
upgrades. Since Carrier has such a wide line of chiller options, it
was easy to find an affordable and sustainable chiller and control
system and that would easily plug into the existing brewing
operation for both phases of expansion,” said Gregg Mello, CE Sales
Representative, Connecticut.
Mello designed the system using two Carrier Aqua Force air-cooled
screw chillers from Carrier’s most energy-efficient chiller product
portfolio. The system was designed to provide 100 tons per chiller
of process cooling and to work in combination with the original
80-ton chiller to provide enough chilling for an 180,000-barrel
production facility. Mello selected Carrier’s Model # 30XA162 with
direct expansion flooded coolers designed especially for low temp
operation. These units are each designed to make 27 deg leaving 33%
propylene glycol mix with a flow rate of 425 gpm producing 100 tons
of process cooling for Two Roads brewery.
In addition, the Aqua Force chillers were provided with low ambient
kits for operation to -20 degree ambient, wye delta starters,
suction line insulation, freeze protection, isolation valves, E
coated micro channel type condenser coils, non-fused disconnects,
control transformers and the Carrier proprietary “low sound package”
to ensure quiet operation and minimal disruption to the brewery
tasting room. The chillers were easily integrated into the existing
brewery infrastructure by utilizing a parallel arrangement to ensure
that they can use the original system as a backup chiller for higher
volume processing. The two Carrier units were conveniently installed
outside the building on two large concrete pads housed adjacent to
the existing cooling system.
Two Roads Brewing Company is also leading the charge in the craft
brew industry with its commitment to energy efficiency and
sustainability throughout their operations. For the expansion
project, Mello specified an upgrade to the standard controls using
BACnet communications, greatly improving the brewery abilities to
control and view their chiller plant. The two Carrier chillers were
supplied with BACnet communications and CE retrofitted the existing
chiller with a Carrier BACnet card. With the Carrier BACnet I-Vu
control system and user interface, the brewery operations engineer
will have the ability to view the chiller plant operation, alarms
and modify settings on the Internet anywhere in the world.
