描述:
Control cabinets with a frequency converter are used to control pumps and fans with a unit capacity of up to 630 kW, in cases where it is necessary to strictly maintain system parameters, such as pressure, flow rate, and coolant temperature. Cabinets can be used to control both single pumps/fans and groups of pumps/fans, including the implementation of a cascade, stepless control mode. When using control cabinets with a frequency converter, in addition to precisely maintaining the operating mode, starting loads on the network are excluded.
