Accurex

Scope Of Work

A complete Accurex kitchen ventilation system with a Vari-Flow variable volume system linked to an exhaust fan (Model XRUD) with a direct drive Vari-Green motor was installed in the new Taco Bell restaurant. The Vari-Flow System senses the heat output of the grill and fryers. As the temperature rises, fan speed increases. The net effect is that air is exhausted and supplied based on the required demand. Also as an additional feature of the Vari-Flow system, the safety backup starts the exhaust fan when the equipment generates 90 degrees F in the hood.

During idle cooking periods, the system can realize up to a 50 percent turndown in airflow. Designed with the temperature sensor in the capture tank versus in the duct collar where many other systems detect heat, the Accurex Vari-Flow provides a response that is up to five times faster than a duct-mounted sensor. This ensures that grease and smoke-laden air is efficiently captured. 

Other Accurex products in the ventilation system included an exhaust fan for condensation application (Model XRED), an appliance-specific fire suppression system (Ansul® R-102), and a wall canopy hood (Model XBEW).
