ZIEHL-ABEGG Elevator EVAC Evacuation Unit

The EVAC 3 model range is purpose-built for elevator technology. Its compact design and sophisticated modules make it ideal for installation in control cabinets (EVAC 3B) or wall mounting (EVAC 3C). These units are compatible with both synchronous and asynchronous motors, offering evacuation capabilities lasting up to 60 minutes and a limited number of rides. To operate, both evacuation units require a battery set that supplies voltage to the frequency inverter and other components. The specific voltage and battery capacity depend on the motor’s technical specifications and the length or number of evacuation trips.

Properties:

The EVAC 3C evacuation unit monitors the elevator system supply network. If one or more supply phases fail, the frequency inverter is disconnected from the supply network. At the same time, the elevator control system is informed about the mains failure. The battery power supply is then connected with a time delay.

The EVAC 3C evacuation unit switches the frequency inverter to emergency mode and the elevator is able to perform one run in either direction at reduced speed.

This avoids the need for lengthy, complicated rescue operations by external personnel
to free trapped persons.

Applications and areas of use:

• Cable elevators with asynchronous or synchronous motors
• Evacuation speed > 0.1 m/s
• Nominal current up to 74 A
• Nominal power up to 37 kW
