Further attention should be paid to the control and energy efficiency where the energy consumption is reduced, and the life of the fan motors is also prolonged.

Frequency inverter

ZIEHL-ABEGG supplies frequency inverters that provide specific benefits for the energy saving control of all types of motors and fans.
Frequency inverters are ideal for use in the energy efficient control of all types of motors. ZIEHL-ABEGG supplies frequency inverters that are perfectly matched to our customers’ applications. The main focus is on ventilation systems, with a special emphasis on ease of handling and operation.

Electronic voltage controllers

For the easy, cost-efficient speed control of voltage variable external rotor motors.
Most ZIEHL-ABEGG external rotor motors are voltage variable. Voltage controllers are available for the easy, cost-efficient speed control of these motors and fans. ZIEHL-ABEGG supplies a wide range of electronic voltage controllers (phase angle controlled devices) and transformer-based controllers.

Control module

UNIcon control modules assume process control functions in the customer application and actuate power controllers, e.g. frequency inverters and ECblue EC fans.
UNIcon universal control modules can be combined with all ZIEHL-ABEGG sensors. The actual value measured on the sensor is compared to the required nominal value.
The UNIcon sensor control module combines sensor functions and control intelligence. The actual and nominal values are compared. Depending on the version, ECblue motors and fans, frequency inverters and other power controllers are actuated by a 0 – 10 V signal or by a MODBUS.

Motor contactor

ZIEHL-ABEGG motor contactors provide additional benefits above and beyond the actual monitoring time and protection functions.
Most ZIEHL-ABEGG external rotor motors are fitted with thermostatic switches (TB). Explosion-proof external rotor motors have a temperature sensor (TP). A temperature sensor (TP) is also integrated in IEC standard motors.
To protect and monitor these motors, ZIEHL-ABEGG supplies suitable products to analyse signals from the thermostatic switch and the temperature sensor.

Sensors

ZIEHL-ABEGG supplies sensors that are specifically matched to the controller.
ZIEHL-ABEGG sensors are specifically matched to ZIEHL-ABEGG controllers. Controllers that permit the selection of operating modes already have measuring ranges and signals for ZIEHL-ABEGG sensors. The power supply for the sensors is integrated in the ZIEHL-ABEGG controller.
