Model MR 21 RC - Vacuum Regulators System Brochure

Dosing devices for aggressive gases and fluids / Dosing devices for gasses / Systems of Vacuum regulators System of vacuum regulators series MR 21 RC General: The MR 21 RC System of Vacuum Regu-lators 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, an M 400 automatic vacuum switch-over, an M 300 C ejector and an M 200 C rotameter. Dosing can be set manually by means of the dosing valve on the regulator. It starts or stops when the the ejector pump switches on or off. The MR 21 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 a 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. The MR 21 RC system ensures uninterrupted dosing even when the cylinder has been emptied or there are several cylinders connected to the collector line. When the cylinders are empty, the automatic switch-over switches vacuum over to the regulator that has full cylinders. In this way the system functions without interruption. The empty cylinders can be replaced without having to stop the system of water disinfecti-on. 1. Chlorine cylinder 2. Vaccum regulator 3. Ejector 4. Booster pump 5. Switchover module 6.

However, planning and installation of the devices must be done by qualified experts. Consideration must be given to the world, European and Slovene standards in order to ensure safe and faultless operation. An authorized service must ovehaul the system once a year. Use of the MR 21 RC at auto-matic dosing of gas chlorine into water on the basis of water flow and amount of free chlorine in water. 1 Chlorine Cylinder 2 Collector Line with Accessories 3 Vacuum Regulator 4 Automatic Switch-over 5 Vacuum Tube 6 Chlorine Trap Heater 7 Probe for Chlorine in the Air 8 Ejector Pump 9 Valves 10 Tube leading to use 11 Ejector 12 Motor Valve with Rotameter 13 AQUAprocessor 14 Writing Device 15 Energy-supply Cabinet 16 Free Chlorine Analyser 17 Flow Meter 18 Gas Chlorine Neutralization 19 Neutralization Energy-supply - Cabinet Order codes: MR 21 A R C/X B T P M F Model El.
