FIRE FIGHTING

AIRMATIC

The Airmatic-RED armor plated tracked vehicle, with its unique high pressure vortex extinguishing technology, is a quantum leap in firefighting and rescue practice. Airmatic-RED performs with agility and speed where difficult or off-road terrain is a barrier and traditional firefighting is impossible, whilst protecting operators and rescued passengers alike.

Airmatic-RED armor plated tracked vehicles are the rapid response go-anywhere rescue system: With its armor plating and self-protecting water spray system, combined with the on-board oxygen support, it can drive through raging fires to rescue those trapped by fire. Quickly empty the vehicle’s flexible water tanks and up to 20 adults can be rescued. The large drop-down tailgate ensures easy access.

Airmatic’s unique high pressure (200 Bar / 2,900 PSI) vortex extinguishing technology, with its rotating nozzles, uses the available water more effectively and efficiently. It enables any vehicle to extinguish fires with a fraction of the water needed by conventional low pressure tenders and is controlled by a simple joystick.

Airmatic-RED armor plated tracked vehicles provide an exceptional level of personal safety for their crew even in extreme heat and explosions from industrial, aircraft or pipeline fires. Active defence also comes when deploying the dozer blade to create firebreaks, extinguish lingering hotspots, or to remove incendiary obstacles such as burning vehicles.

ORCATECH

ORCA® system for the removal of oil and hazardous substances

ORCA® is a state-of-the-art, cost-effective and highly efficient system which mechanically
cleans away oil and severe contamination. In concordance with future test criteria for the
mechanical removal of oil, far better proven results are achieved in restoring tyre grip,
compared to the results which can be obtained when using oil-binding agents. The number of
accidents subsequently occurring on surfaces where oil has been cleaned away can thus be
reduced considerably. Apart from its use in the removal of oil, the ORCA® system is suitable
for all applications where caution must be taken to remove completely any substances which
will contaminate the water supply.

The cleaning principle is based on the patented high-pressure, twin chamber, vacuum
process whereby first of all a water/tenside mix is applied, via a rotating vortex process under
a rotor hood which is sealed to the outside, at a pressure of 200 bar to the surface to be
cleaned. Due to the high water pressure, the water/tenside mix is pressed into the capillaries
and rinses out the substances present in the cavities in so doing. What is remarkable is the
low water consumption - a maximum of 20 litres/min.

The high suction performance in the high-pressure, twin chamber, vacuum process
guarantees that all residue is safely taken up into the waste water tank of the appliance.
The rotor hood is equipped with an integrated second suction chamber for air acceleration
and a negative pressure regulation device which operates independently. This ensures a
consistently high suction performance during operation, even in the case of uneven or
different surfaces. This also prevents any residue from running back out when the rotor hood
is raised.

Within the rotor hood, a partition wall constitutes the integrated suction chamber, in which a
considerable acceleration of air takes place. A strong Venturi effect is produced at the lower
edge of the partition wall which is essential for being able to suck effectively those
substances which adhere firmly to the ground, such as oil, for example, from deep within
fine pores. In addition, thanks to this design a shallow flow of air is fed compulsorily along the
ground which also guarantees that the contamination on the ground is sucked up in the first
chamber as well.

In order to be able to remove very sticky substances from pores, very strong air flows are
needed in the rotor hood which are guided in a specific direction. In the automatic negative
pressure regulator, flexible ventilation elements, in conjunction with the Venturi effect
produced by the partition wall in the suction chamber, ensure a constant and controlled flow
of air which is particularly effective low on the ground. If the ground is even, then these
elements open and allow more air volume into the suction hood. If the rotor hood is moved
over uneven ground, then these elements close and a large part of the air inflow takes place
via the gap at ground level whereby the emergence of waste water is prevented even in the
case of deep ruts.

With this high-pressure, twin chamber, vacuum technology, results are achieved which
cannot be obtained with conventional cleaning methods.
