Certifications
The EMS Model has been certified by ITS. This certification mark indicates that the product has been tested to and has met the minimum requirements of a widely recognized (consensus) U.S. and Canadian products safety standard, that the manufacturing site has been audited, and that the applicant has agreed to a program of periodic factory follow-up inspections to verify continued performance.
Model EMS Series are ETL Listed under file number 3132576CRT-001a and comply with UL508A Standards and CAN/CSA C22.2, No. 14-05 Standards.
CaptiveAire's Energy
Management System
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.
