Electrical control panels and devices for management of commercial kitchen extraction fall into a two main categories.
Energy management - devices that regulate and monitor energy consumption within a commercial kitchen extraction system
D.C.K.V - Demand Control Kitchen Ventilation - a system that measures cooking activity and controls fan electrical consumption accordingly. Very effective at saving energy.
V.F.D - Variable frequency drives - provide specific control frequency voltage and power, tightly regulated - great for fan protection and energy saving.
Gas Safety
Gas interlocks safety panels and solenoids - devices that prevent gas supplies leaking - these are a mandatory requirement
Carbon Dioxide monitoring and proving -
Building management interfaces
No volt contacts for interfacing with house systems or provide relaying information
