How Cheetah™ Works

Cheetah™ consists of a number of electronic modules which are interconnected by a data-communications network. Sensors installed into the canopy and ducts are used to monitor the cooking environment.  A sensor processor unit uses the data obtained from the sensors to calculate the ideal rate of airflow. The sensor processor sends commands over the communications network to motor-speed controllers which in turn control the flow of electricity to the extract fan motors.

The system is configured and operating parameters set at installation, directly onto the network from a laptop .  The normal mode is for continuous automatic control, with a minimum fan speed of 40%.  There are infinite operating modes and settings which can be installed to suit the particular conditions encountered and customer's requirements.

The display incorporates an override button to increase the fan speed to 100% for a pre-defined time, fault lights and a scroll button to observe operating data and fault details.  The system can be configured on installation through a network connection on the display.

The datalogger stores the fan speeds, temperatures, air flows, smoke/steam sensor operation and energy monitoring information and remote access to the data is provided via an inbuilt modem.  This uses a 2-way GPRS protocol to monitor the system at base, also allowing settings to be changed remotely, performance to be optimised and faults rectified.
