EMS Series
Adobe PDF Version 
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.


   Standard Features and Benefits    
  • Full capture and containment of heat loads while still reducing energy costs
  • 20% reduction in fan speed equates to a 48% reduction in fan energy costs
  • 100% Airflow Override button with a fully adjustable timer
  • Controls up to (4) 5HP inverter duty motors
  • Low Maintenance – Monthly temperature probe cleaning only
  • Adjustable Set-Points Include: Fan Low Speed, Fan High Speed, Fan Activation Temperature, Fan High Speed Temperature, and Ramping Rate
  • Meets the requirements of IMC 507.2.1.1. which require exhaust fans to activate when cooking appliances are energized
  • Installed in Exhaust Hood utility cabinet and can be factory wired. Panel can also be wall mounted.
  • Fully modulating Digital Temperature Control
