Innovation: It’s part of our DNA Large enough to deliver. Small enough to care.

Innovation is everywhere at Blue Reef. For example, the chemical products which we have produced for the anti-scalent market are unique in every way. Our “HEXAMER” based products are formulated and manufactured employing processes previously never used in the manufacture of water treatment products.
Not only does this make the products far more stable than traditional inhibitors, but one is able to actually test for the active aspect in the product. This takes scale inhibition and scale removal to a new level in that chemical dosing rates can be calculated very accurately resulting in cost savings and increased efficacy.
