4. OPERATING
PRINCIPLE
The BASE and CATALYST materials are sent to the mixing machine from 2 pumps or pressure tanks.
Each material crosses a piloted valve, a meter. The cycle begins with the simultaneous opening of the
CATALYST and BASE valves. The 2 meters send their informations to the computer that shuts off the
catalyst valve when the computerized mixing ratio is reached.
The mixing process is based on a base constant flow. The catalyst flow is injected low in frequency and
regulated in pressure. The injection is made directly into the base flux at the mixer level.
The automaton (PLC) checks continuously the mixing ratio and if it notices a fault that it cannot correct, an
alarm is activated. The machine goes on safety mode.
