There are two types of automatic chlorinators, inline and offline. This refers to the way each of these automatic chlorinators are installed. Each type has its advantages and disadvantages. An inline chlorinator is good for initial installations. They install directly in line with the other pool equipment. The advantage of this is that you don't have to worry about the chlorinator tipping over or taking up extra space on your equipment pad. An off line chlorinator installs on a separate line from your existing plumbing. This system is great for retrofit applications because of the ease of installation. The disadvantage is that you have extra equipment sitting on your equipment pad taking up space.
