The project

 Wentworth Institute of Technology was looking for a solution to save energy at Beatty Dining Hall but had the challenge of multiple hoods connected to single exhaust fans. The kitchen layout included
newer hoods that had been integrated with an old existing main cookline for a total of nine large exhaust hoods. With typical DCKV systems, the fans would need to be commanded to full speed
any time cooking activity was detected to ensure that no smoke/temperature rolled out of any of the hoods. How could energy savings be achieved with this multiple hood-single fan layout?

Solution

ECOAZUR was the perfect solution for this situation by being able to retrofit modulating dampers on all hoods in combination with the
ECOAZUR optic and temperature sensors to maximize the energy savings in the kitchen. Some exhaust hoods required further
customized dampers to ensure that no existing ductwork or hoods in the space needed any alterations. ECOAZUR was fully integrated with Beatty Dining Hall’s BAS so system information can be gathered by facility staff in real time. Wentworth is now achieving energy savings that surpass the initial estimates and will be enjoying these savings for years to come. Note the exhaust fans now never reach 100% speed!
