High pressure water fog extinguishing system

Pfizer Manufacturing Austria GmbH

Automatic high pressure water fog extinguishing system to protect a laboratory & office building

Pfizer Manufacturing Austria GmbH is a subsidiary of Pfizer Corporation. The company is known worldwide for its groundbreaking medical inventions and ultimately for the production of a COVID-19 vaccine.
The location Orth a. d. Donau covers a broad spectrum of Pfizer Manufacturing Austria GmbH. In particular, the quality control of already produced and also newly invented drugs takes place in the refurbished and expanded part.

With the newly installed HI-FOG® 2000 system, the building is optimally protected in the event of a fire. A high-pressure water mist extinguishing system uses about 80% less water than a conventional sprinkler system. This saving is already evident in the stocking and especially after a fire incident, as much smaller water damages are found on the building. Thanks to the new EPU (Electric Pump Unit) unit, the power consumption of the system can also be optimized even more efficiently, as the pump unit only switches on the number of motors that are actually needed. Likewise, there is no pressure-maintaining pump installed in the new unit generation, as this task is taken over by the 1st motor controlled by a frequency converter. In this way, the "down time" of the plant and service costs can be minimized.
