On 11 September 2013, the VdS commissioning of a new production hall at a Greman motoroil producer took place.
The by Calanbau Brandschutzanlagen GmbH installed InnovDos foam proportioning system is set for 18.000 liter per minute with a foam mixing percentage of 1%. During several water- and foam tests with a water flow of 500 liter per minute till 18.000 liter per minute, the deviation of the mixing percentage was always under 10%.
This InnovDos system exists out of 3 proportioners type MBWP-6 and a foam pump type AP 09. The remaining fire water that was used to drive the foam pomp by a pelton wheel was collected in a water collector under the foam pump and pumped back into the water storage tank. The attendees of VdS were very content with the tested values. The pressure loss in the InnovDos foam proportioning system at a water flow of 18.000 liter per minute is 0,95 bar.
