Mains fed coolers are basically a large scale filtering and cooling system. The water in this system passes through a filtering system eliminating all water impurities and giving an unlimited supply. The benefit of this type of water cooler is that it saves the hassle of refills and once you have the it up and running you don't need to do anything. This type of is also much more practical for companies with a large number of employees.
