Chlorinaton system MR 21 RC (capacity up to 15 kg/h)

The MR 21 RC System consists of :

  • Two M 20 C vacuum regulators
  • M 400 automatic vacuum switchover
  • M 300 C ejector 
  • M 200 C rotameter

GENERAL

The MR 21 RC Chlorinaton System is designed for dosing gas chlorine and with minor alterations also for other gases, working on the indirect vacuum principle.

The MR 21 RC System consists of :

  • Two M 20 C vacuum regulators
  • M 400 automatic vacuum switchover
  • M 300 C ejector 
  • M 200 C gas flowmeter

Dosing can be set manually with the rate valve of the regulator. It starts or stops when the ejector pump switches on or off.


OPERATION PRINCIPLE

The MR 21 RC system ensures uninterrupted dosing even when the cylinder is empty or there are several cylinders connected to the collector line.  When the cylinders are empty, the Vacuum switchover automatically switches over the vacuum to the regulator that has full cylinders. This way the system functions without interruption. The empty cylinders can be replaced without having to stop the system of water disinfection.

SYSTEM EXTENTION OPTIONS

The MR 21 RC system can be extended by additional gas flowmeters 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 a suitable ejector must be added to it. When adding gas flowmeters to the system, it is important not to exceed the capacity of the regulator.
