Strong ROI for Kitchen Hood Demand-Control Ventilation

Edgewood College had an energy conservation fund with strict technical and payback criteria.The old kitchen HVAC systems in Predolin Humanities Center and Regina Hall were selected for upgrades.The goals were to save energy, reduce noise levels, decrease grease entrapment, and reduce HVAC equipment wear.

 

TEL provided engineering, installation, commissioning and O&Ms for conversion of Constant Air Volume (CAV) kitchen hoods to Variable Air Volume (VAV). Installed TEL chip-based kitchen control system whose sensors automatically regulate fan speed based on cooking load, time of day, and hood temperature.

“Remarkable! Very, very happy with the outcome. Your guys were awesome. Documentation was also more than expected. Follow-up service has been exceptional and timely. Thank you!”
