Help your food service clients reduce energy costs in the kitchen with Greenheck’s Vari-Flow integrated kitchen ventilation systems. These systems precisely modulate exhaust and supply airflows to match cooking operation demands. Temperature sensors located in the hoods’ capture area respond to cooking load changes five times faster than duct-mounted sensors, which is what most existing variable volume systems use. This feature, coupled with fan-speed turndown of 50% and high efficiency Vari-Green motors, can dramatically reduce electrical, heating and cooling costs.

Two types of controls are available; an easy-to-use keypad or a new advanced touchscreen control that includes independent light and fan control, programmable fan scheduling, VFD control, and help diagnostics to monitor energy usage. Live and historical energy monitoring and trending information is also provided. Greenheck’s Vari-Flow system is compatible with BACnet MSTP/IP, LON and ModBus for easy integration into most building management systems.
