EMS Series
The ETL listed Energy Management System is designed to automatically reduce exhaust and supply airflow
quantities while still completely capturing & containing heat and smoke generated by the cooking appliances.
Exhaust and supply fans modulate between factory set low speed, while the appliances are idling, and high speed.
This modulation is dependent on the duct temperature sensed. A 100% airflow override button is also supplied with
an adjustable timer that is factory set at 30 minutes.
The modulation of the fans between low and high speed is adjusted by variable frequency drives. The
use of variable frequency drives allows for a 20% reduction in airflow at the appliance idle
temperature. The modulation of the fans during cooking operation allows for maximized energy
savings versus a fan running on high speed during the same cooking period.
An adjustable, fully modulating temperature sensor is mounted in the exhaust duct and monitors the exhaust air
temperature. The sensor then works in conjunction with a panel mounted temperature controller. The EMS panel is
capable of controlling up to four inverter duty motors.
