Drewphos™ boiler water treatments
Drewphos boiler water treatments include a family of pre-blended sodium-phosphate solutions that effectively minimize the potential for caustic-based corrosion in high-pressure steam generating systems. These easy-to-use products, which are primarily used in systems requiring coordinated, congruent and equilibrium phosphate/pH treatment, are formulated with various sodium-to-phosphate ratios to allow for the optimization of boiler water chemistry.
Drewphos products may contain a polymeric dispersant to enhance deposit control performance. The hydrothermally stable polymer helps to ensure that any iron returning with the condensate does not result in waterside deposition. Drewphos boiler water treatments meet FDA regulations for steam host requirements.

Method of Application
Drewphos boiler water treatments are typically fed continuously, either neat or as a dilute solution, directly to the boiler. Demineralized water or condensate should be used when preparing dilute solutions.
