The MT Industrial – along with the MT Municipal, MT Airport, and MT Forest – has an MT series application classification. The modular construction and the flexible combination possibilities of the Modular Technology series (MT for short) enable such unique vehicle configurations that they can also be specially customized for use by plant fire departments in the industrial sector.
But what does an MT vehicle used in an industrial environment need to be able to do?
The greatest challenges of fires in industrial plantsare not only the substances and materials that can catch on fire, but also the often large quantities of precisely these substances. For many of these liquids, substances, and materials, extinguishing with water or a conventional water-foam mixture is not enough, and specially adapted foam compounds as well as precisely set foam proportioning ratios must be used. Whether in the chemical industry, the petroleum processing industry, the pharmaceutical industry, or other industrial facilities, the raw materials and end products are always produced and stored in large quantities. This usually leads to fires being larger and, above all, lasting longer. As a result, industrial firefighting vehicles have to cope with continuous duty for hours or perhaps even days on end, on the one hand, and be designed for large flow rates of extinguishing agent and large application ranges of this extinguishing agent, on the other. Since the tank capacities of the fire trucks are limited, stationary hydrant networks are often used to support or supply the vehicles, and these are also dimensioned accordingly.
All this information is necessary for Rosenbauer to optimally conceive an industrial firefighting vehicle, and they also impact the design of the vehicle. The size of the possible burning objects as well as the necessary quantity of extinguishing agent determine the size of the fire pump. With the MT Industrial, output rates of 13,000 l/min in tank suction operation and up to 20,000 l/min in feed-in mode from a hydrant network are possible with the N130 normal pressure pump. If a hydrant network is used, then a foam pressure proportioning system must be used for foam proportioning which is specified according to the flow rates. On this system, it must then be possible to set the usual foam proportioning ratios for the foam compound used and for the flammable material. Industrial firefighting vehicles often also have two different foam compounds on board in order to be able to react more flexibly to the fire event. When using a hydrant network, the water tank on the fire truck is often completely dispensed with and only the foam compound is transported for proportioning. In order to get the large quantities of extinguishing agent into and out of the vehicle, the inlets and outlets of the pump unit must be defined accordingly. To ensure that the fire can be fought from a sufficient or safe distance, the extinguishing agent is usually applied using powerful turrets with flow rates of up to 13,000 l/min and throw ranges of up to 130 m. These can be operated by radio remote control, so that the emergency crews do not have to remain on the roof of the vehicle for hours or days at a time.
Here, the MT Industrial enables an individual yet standardized implementation of these challenging requirements for industrial use, and it can be operated like any other Rosenbauer vehicle thanks to the intuitive control provided by the Rosenbauer Logic Control System.
