MC3000 fully integrated
Short description
The fully integrated model contains all components of a CAFS unit within one assembly. Centrifugal pump, compressor, foam agent proportioning pumps, the patented MicroCAFS mixing valve and the MicroCAFS management system (CMS) with all components for measuring and controlling are mounted on a base frame. The pipework of all components including outlet valves is already assembled as well.
- ready for use built system "plug and play"
- connection to the pto by only one shaft
- compressor is driven internally by a tooth belt via pump gear, without additional pto
- precise positive pressure proportioning foam pump by exzentric worm pump, volumetric, no calibration needed
- no flushing of foam pumps necessary after use
- simple one button operation, every function can be switched by only pushing one button
The module is delivered completely mounted and can easily be integrated in the vehicle. The mechanical connection to the PTO of the vehicle is made by a standard transmission shaft. The compressor is already connected to the drive of the centrifugal pump with a tooth belt internally in the assembly. Only this one transmission shaft is needed to drive the pump and the compressor at the same time. The electrical power supply is given from the 24 volt wiring system of the vehicle. The pipework of the CAFS unit must be connected to the pipe installation of the vehicle also by the vehicle manufacturer.
In the standard configuration the foam dosing is done by two excentric worm pumps. Up to 4 pumps can be arranged optionally. The flow measuring is done by hightec magnetic inductive measurement. Independent of the type of the foam agent (viscosity) the accurate dosing will be made by the excentric worm pumps. Also the reliable dosing all over the working range is guaranteed under different working pressures.
CAFS is produced in the patented MicroCAFS mixing valve without remarkable pressure loss and without limitations of the water flow as well. Compressed air will be injected in the water/foam flow by proportional pressure regulation valve into the mixing valve. According to the quick reaction of the measurement and regulation, the unit can also handle quickly changing operating conditions (e.g. during chopping).
The unit allows CAFS flow rates up to minimum 800 l water per minute (about 1.200 l/min CAFS flow). This results in expanded CAFS flow of about 3.200 l/min. Therefore it also fits for using a monitor with about 1.200 l/min or several nozzle pipes at the same time. The unit provides high capacity for efficient and safe firefighting, also for indoor firefighting and industrial firefighting. Basic rules (tactical and technical) and sufficient self protection for attack teams have to be considered by fire fighting with CAFS as well. The attack teams must be trained regularly and constantly to enhance effectivity and safety for firefighting with CAFS.
