Your largest water filtration needs are no match for the OptiPure BWS1500/300 HF Plus. This massive system has the capability of producing up to 1500-gallons of optimized water per day, giving you the ability to control and maintain the removal of the Total Dissolved Solids (TDS) from your water as well as well as adding back in the additional minerals used to balance water quality. Not only does water quality affect flavor, it can also cause great damage to your equipment, making this filtration system an essential tool in your line-up.

If you are needing a large system to eliminate the majority of hardness minerals in your water, this pump-driven system provides the necessary bandwidth. The OptiPure BWS1500/300 HF Plus includes integrated pre-filtration with particulate and chlorine reduction, reverse osmosis, blend valve adjustment, and mineral addition, all wrapped up in a space-saving package that can easily mount to the most convenient wall.

Starting with its high-capacity carbon pre-filtration system, chlorine, sediment, off-tastes, and odors are removed from your water in order to increase the lifespan of the filtration system and produce cleaner water. After the water moves through the carbon pre-filter, Reverse Osmosis (RO) removes up to 97% of the water's Total Dissolved Solids (TDS) using a semi-permeable membrane. After the RO process, a balance of minerals is dissolved into the RO water at roughly 40-70ppm with 75% calcium and 25% magnesium.

The most exciting feature on the OptiPure BWS1500/300 is the blend valve that allows you blend any amount of carbon filtered water with RO water to achieve your desired TDS. You can adjust the blend valve to increase or decrease your total TDS, producing Optimized Water, perfect for brewing coffee or espresso, or any other situation where water quality if important. Because the taste and cleanliness of your water is crucial to the quality of your coffee, having the ability to so easily control these factors with the blend valve is a game-changer.

On top of all of these features, there is a 300-gallon atmospheric storage tank with a sub-micron air breather and a 1hp floor-mounted re-pressurization pump, a 16-gallon buffer tank assembly, and a 1" outlet that allows for high-flow application. Simply put, if you have high-capacity water needs, the OptiPure1500/300 HP Plus is the perfect match.
