The Point-of-Use coolers are available in hot/cold models and are ready to be ordered. We also stock water filtration systems including a reverse osmosis system and an ozone sanitization system and an In-Tank UV system. All of our filter systems can be used on water coolers and/or coffee brewers. They are shipped assembled and are simple to use and replace.
