Functional Principle
The
ROSENBAUER DIGIDOS
is an electrically driven direct-
injection foam proportioning system.
The system is controlled using the LCS control unit.
A
gear pump
is used as the foam compound pump. This pump
type -
no inlet or outlet valves
- is characterized by extremely
high operating safety
.
Furthermore, this proportioning system has very
precise
regulation
of the proportioning rate - essentially independent
of the viscosity of the foam compound. This is achieved by
continually comparing the measured water flow, the pre-
configured proportioning rate and the foam compound flow
rate actually injected.
