UV Ballast or Controller Unit - This is the [brains" of the UV system. Some systems have a very simple controller, and others have a more complicated system that includes alarms, lamp change timers, trouble indicator lights, and more. Although UV units vary in complexity and size, all controllers do basically the same thing of controlling the electrical output of the lamp and powers the UV-C light needed for water purification.
Inlet for untreated water.
UV Chamber - This part of the system houses the UV sleeve and lamp, and also controls the flow of water through the system.
Outlet for treated (clean) water.
UV Lamp (or bulb) - The lamp of a UV system produces UV-C, which is UV light considered to be germicidal. However, different lamps perform different functions, so they type of lamp used will be contingent on the application and disinfection requirements
UV Quartz Sleeve - The quartz sleeve of a UV system is the long, cylinder-shaped tube. The tube is made of quartz glass and is there to protect the UV lamp which is powered by electricity from the flow of water. The UV lamp transmits light through the tube into the water. It is important to clean the sleeve (generally when the lamp is changed) as minerals and contaminants in the water can cloud the glass tube.
UV Sensor - Available option on most UV systems, the UV sensor monitors and indicates the intensity of the UV light. If the intensity becomes too low, even though the lamp is on, an alarm is triggered.
Solenoid Valve - Available option on most UV systems, the solenoid valve automatically shuts the water off if the system is not functioning properly, preventing the possibility of contaminated water flowing through the system that is not treated properly.
Flow Meter - Standard on some UV systems, the flow meter calculates the actual real-time UV dose delivered for a particular flow rate, ensuring water is treated properly.
