Anti-Fire Set PPA-01

PPA-01 “STAND ALONE SYSTEM”
The system’s setup allows it to stay prepared for action for long periods of time. In this variant the starting system is based on the use of pyrotechnical cartridge. The hot gases impinge the turbine vanes and start the system. The system is energetically independent and is capable of preserving adequate area from fire in all conditions. In this variant the system works automatically (without operators).

PPA-01 “TRANSPORTABLE SYSTEM”
Two operators can manually transport the anti fire set. Together they are capable of preparing it for operation and starting. Starting the set is done by a small two-stroke piston engine, which needs to be started manually. Primary filling of the suction tube with water is achieved by decreased pressure, which is very simple and fast. Ejector decreases the pressure in the suction tube.

PPA-01 “AS TELEGRAPH MODE”
In the situation where the water source is far from the fire area there is a possibility to serially connect large numbers of these anti fire sets. Working in the telegraph mode is very useful although very complicated. This mode needs sophisticated methods for conduction of fire slaking. Because of that, the main stone of the method is anti fire set and its control possibilities.

Scheme of serial anti fire sets connection.
The number of nodes depend on hydraulic loses.
The individual geometrical parameters are:H (m) horiyontal distance
V (m) vertical distance
S (m) hose length
