CPC systems were born to create an alternative to conventional bladder tank systems. In contrast to the conventional bladder tank systems, foam concentrate stored in the pressure vessel is forced by using impellent gas to create an accurate mixture at the system outlet. While the system is in standby position, the foam concentrate tank is not pressurized, level measurement or replenishment is much easier than in the conventional bladder tanks. Pressure enters the CPC mixer employed simultaneously to proportion the foam concentrate flow. A pneumatically actuated valve provided between the pressure vessel and the CPC mixer, isolates the line to ensure the foam concentrate consumption only when needed. A level indicator, pressure gauge assembly located on the shell helps the user to put the correct amount of foam concentrate in the vessel. Pressure vessel needs no maintenance while the pressurizing group needs to be supervised periodically. C.S.I. S.r.l. has obtained the H1 certificate according to the PED 97/23 directive. This certificate enabling our company to mark the CPC pressure vessels with CE. CPC systems are limited to 5000 liters capacity and equipped with up to 8” mixer providing a foam concentrate flow rate up to 8100 l/min.

Le bombole di gas compresso (CO², N₂ o aria compressa) sono azionati dal flusso d'acqua che passa attraverso il mixer. La pressione del gas, convoglia il liquido schiumogeno (anche schiumogeni concentrati con valori di viscosità differenti) a fluire attraverso un orifizio calibrato creando un premiscelato con i desiderati rapporti di miscelazione. La perdita di pressione creata dal miscelatore è limitata a 1 bar alla portata massima indicata alla tabella dei mixer. Un regolatore di flusso auto bilanciato controlla la pressione della linea schiuma (indicato come “R” al disegno schematico) assicurando il corretto flusso del concentrato schiumogeno creando un preciso rapporto di miscelazione (1%, 3% o 6%).Il sistema funziona su una vasta gamma di portate come si evidenzia dalla tabella “Portate” allegata, miscelando perfettamente anche con valori di pressione diverse della pressione di ingresso acqua.

Pressured Gas cylinders (CO², N₂ or Compressed air) are actuated by the water flow passing through the mixer. Gas pressure, forces the stored foaming liquid (Also foam concentrates with different viscosity values) to flow through a calibrated orifice to create a premix with desired mixing ratios. The pressure loss created by the mixer is limited to 1 bar at the maximum flow rate indicated at the mixer table. Pressure controlled foam line flow regulator (indicated as « R » at the schematic design) ensures the correct flow of the foaming liquid to create a precise mixing ratio (1%, 3% or 6%). System functions at a wide range of flow rates and also different pressure rates of the inlet water.
