■ The 2” automatic bypass systemwill allow
any of the 2.5 - 3/4” injectors, to work on
a 2” line and ensure a fully proportioning water flow
rate method, between the 2” main line and the 3/4”
sub main line.
■ The ratio of 10:1 between main - to sub main line, will
be kept at the range of 6-25 m 3 total water flow rate,
regardless to the pressure or flow rate fluctuations.
If one will set the injector to 1%, he will get actual
dosing of 0.1% on the main line.
■ The fitsmostwater treatment applications
that require low dosing.
■ The system will work solely by water
pressure.
■ The system can be combined with MixRite
PVDF models, allowing to dose aggressive acids, for
PH control, or chlorination models, in order to dose all
types of Chlorine products.
■ The system is delivered pre-set, equipped with 2” BSP
male- inlet/outlet threads.
