PROJECT DETAILS

Highlights

Q Duct installed in a short time frame to provide improved IAQ.
Q Shed was utilized to eliminate water pooling on top of ductwork.
Rebate from the local energy providers available.

The previous metal duct lined with fiberglass was severely damaged due to pooling water and harsh weather conditions.

Background

Minnesota Adult & Teen Challenge reached out to SVL regarding an old leaky duct system at their Stevens building. SVL worked with AQC Industries, to supply their Q Duct system. While onsite, the AQC team noticed the severe deterioration of the existing ductwork. This finding was shared with the Minnesota Adult and Teen Challenge, and the coordination began to replace the duct at the time of an RTU upgrade.

Challenge

In January, the outside temperatures reduce the amount of time the HVAC system can be down without risking damage to the rest of the building. The old duct system was deteriorated and required some time to dismantle. Additionally, the new duct would need a retrofit to maximize the existing layouts and taps. The old metal duct was corroded from pooling water on its exterior. The water then moved into the fiberglass insulation, causing mold and diminished indoor air quality.

Installed Q Duct on the roof of the MNATC Stevens Building with Q Rail, Q Shed, and Q Lok.

Solution

SVL recommended Q Duct for the project. Q Duct’s exterior material offers all-weather protection and doesn’t rust like metal ductwork. SVL minimized the air handling unit downtime required with Q Duct’s fast and economical installation process.

Q Duct consists of lightweight material, is durable and the construction reduces the number of people necessary to install the system. The duct pieces also fit together quickly, efficiently, and faster than typical outdoor ductwork. AQC stocks Q Duct parts for quick production lead time, even with custom ductwork projects.

Q Duct’s features made for an easy to retrofit to the layout of the old duct system. The Q Rail® mounting system secured the ductwork to the roof quickly and easily. The Q Duct water pooling solution, Q Shed®, has a slight slope to the top of each Q Duct piece, which allows precipitation to roll off the ductwork.

The final feature implemented on the Stevens Building rooftop duct system was Q Lok®. Q Duct’s interlocking connections provided a secure and fast installation process. Q Lok connection has a near-nil leakage for further saving.

End Result

The Q Duct was installed on the Stevens Building roof and its custom features (Q Rail, Q Shed, and Q Lok), helped improve the facility’s indoor air quality. SVL and Kraft Mechanical worked hard to reduce downtime. Lee Pawlik, the Minnesota Adult Teen Challenge HVAC Technician, was pleased with the long life, innovative design, and outstanding warranty that instilled confidence in the new AQC duct system.
