MR 20 RC

General:
The MR 20 RC System of Vacuum
Regulators is designed for dosing gas chlorine
and with minor alterations also for other
gases, working on the indirect vacuum principle.
The MR 20 RC System consists of an
M 20 C vacuum regulator, an M 300 C ejector and an M 200 C rotameter.
Dosing can be set manually by means
of the dosing valve on the rotameter. It starts
or stops when the ejector pump switches on
or off.
The MR 20 RC System can be extended by additional rotameters which have to be installed parallel to the
existing one. This way the system can be extended to
several dosing points, but in this case suitable ejector
must be added to it. When adding rotameters to the
system, attention must be paid not to exceed the capacity
of the regulator.

OPTION:Multipoint chlorination system

The system can be extended also in the
way that it makes semiautomatic dosing possible. Where there are several pumps in the watersupply system and their capacities known, each
pump can be extended by an ejector and a rotameter, and connected parallel to the regulator.
Dosing can be blocked by means of an electromagnetic valve.
