Eco Tec - Bright Dip Recovery

Eco-Tec DPU™
Phosphoric brightening produces a highly reflective finish to aluminum for the automotive and appliance trim, lighting fixtures, bathtub enclosures and shower door manufacturers. High losses of phosphoric acid during rinsing leads to substantial operating costs. The Eco-Tec DPU™ system purifies the water rinses and returns acid back to the bright dip process.
