TRANSPORTATION
Short-circuits and electric shocks due to incorrect application of the
voltage!
Current can injure persons and destroy the devices. Before commissioning,
disconnect the entire system from the power supply and check the connections
after applying power.
Accidents during installation or maintenance due to electrical voltages!
When carrying out installation or maintenance work, disconnect the modules
from the power supply (pull out the mains plug). This prevents accidents
caused by electrical voltages.
Electric shocks and material damage due to excessive voltages.
Non-compliance with the specified voltage limits can result in electric shocks and
the modules can be destroyed.
Only use the approved components in the system.
Risk of injury from electric current.
Current can injure persons and destroy the device. For this reason, disconnect
the system from the power supply before installation.
Risk of injury and material damage through non-observance of the
operating instructions.
Always read the operating instructions before planning the system in order to
avoid or reduce risks and damage. (The instruction leaflet does not replace the
operating instructions of the product.
You can also find these operating instructions at www.luetze.com.

The AirBLOWER is intended to provide a balanced climate in switch cabinets,
avoid heat nests (so-called hotspots) and protect the components from
overheating.
Three PT100 temperature sensors of the AirBLOWER LCOS-AB-I control unit
continuously measure the temperature in the control cabinet. If the previously set
temperature limits are exceeded or not reached, the AirBLOWER fan bank is
activated and the control cabinet temperature is adjusted accordingly.
A control cabinet equipped with an AirSTREAM frame has improved heat
dissipation. Practical tests provide impressive results: With the AirBLOWER, the
average cabinet temperature can be reduced by up to 10K.
Operation of the LÜTZE AirBLOWER requires significantly less energy than
active control cabinet cooling. In addition, the AirBLOWER does not have to be
used in continuous operation, but can be operated in clocked mode.
The AirBLOWER consists of three modules that are connected to each other. The
individual modules are presented below.
