Measurement and control
The measurement of actual values is extremely important for the efficient operation of ventilation systems. For this task, HLU has special components that can be used in chemically aggressive exhaust air.
The measured values are used for simple system monitoring or as input signals for a higher-level control system that controls the actuators in the system in question.
