1 Dosing equipment for aggressive gases Full vacuum system for maximum safety Chlorine wetted parts made of high quality materials for maximum reliability SYSTEM EXTENSION OPTIONS The MR 20 RC System consists of: M 20 C vacuum regulator  M 300 C ejector  M 200 C gas flowmeter The MR 20 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 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. Multipoint chlorination system The MR 20 RC Chlorination System is designed for dosing gas chlorine and with minor alterations also for other gases, working on the indirect vacuum principle. Dosing can be set manually on the rate valve of the regulator. It starts or stops when the ejector pump switches on or off. It is very simple to mount vacuum regulators. However, installation of the devices must be done by qualified experts taking in consideration all required international standards in order to ensure safe and faultless operation. An authorized service must overhaul the system once a year. 1. Chlorine cylinder 2. Vacuum regulator 3. Gas flowmeter 4. Ejector 5. Booster pump Semiautomatic dosing system Where there are several pumps in the water-supply system with known capacities, each pump can be extended by an ejector and a gas flowmeter, and connected parallel to the regulator. Dosing can be blocked through electromagnetic valve. Activation of the electromagnetic valve depends on the known flow changes. 1.Chlorine Cylinder 2.Manifold with Accessories 3.Vacuum Regulator 4.Vacuum Tube 5.Electromagnetic Valve 6.Gas flowmeter 7.Ejector 8.Ejector Pump 9.Valves 10.Tube leading to use
