StratoVent's Energy Management Systems (EMS) are ETL Listed and
designed to modulate effectively to reduce exhaust and supply airflow rates while
capturing and containing all heat and smoke generated by cooking appliances.
Operation of the Energy Management System (EMS) is based on a modulating principle where the fans modulate based on the duct sensor temperature reading. A ductmounted temperature switch constantly monitors exhaust air temperature and forces the system to adjust speed thus saving energy in idle mode. Low speed is factory set to reduce airflow by 20%. For extended heavy cooking timeframes, a 100% airflow override option and adjustable timer (factory set at 30 minutes) are supplied.
The EMS is available in three different phase configurations and various sizes. All panels include adjustable variable frequency drives to adjust the high-speed set point and lowspeed set point. The panels include color-coded wiring / wiring diagrams and spare terminals controlled by the fire system micro switch. Units are factory pre-wired to shut down supply fans in a fire condition. A factory pre-wire option is available to turn on the exhaust fans also in a fire condition (if required). Panel is ETL-Listed to US and Canadian Standards for installation in the integral ETL-Listed Utility Cabinet.
