1 Dosing equipment for aggressive gases Full vacuum system for maximum safety Chlorine wetted parts made of high quality materials for maximum reliability The MR 21 RC Chlorination 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 switch-over  M 300 C ejector  M 200 C gas flowmeter  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. 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. 1. Chlorine cylinder 2. Vaccum regulator 3. Ejector 4. Booster pump 5. Switchover module 6.
