ULTRAMARINE High-Pressure Boiler Water Treatment Program
The ULTRAMARINE High-Pressure Boiler Water Treatment Program revolves around the independent utilization of "disodium phosphate" and "caustic soda" in such a way that no "free caustic" is generated in the boiler water. At the same time, proper pH levels are produced and excessive phosphate concentrations are minimized.

The ULTRAMARINE High-Pressure Boiler Water Treatment Program went into effect in the marine industry in the 1960s, and it was quickly recognized as the cornerstone of a successful high-pressure boiler operation onboard ships. It continues today as the most effective, proven high-pressure boiler water treatment program for all marine steam generator systems.

DREWPLEX® dual treatment program
This unique program combines DREWPLEX AT boiler water treatment designed to eliminate heat-reducing scale and deposits caused by excess hardness in feedwater with DREWPLEX OX corrosion inhibitor, a highly effective oxygen scavenger, which protects the entire boiler system from oxygen corrosion.

The DREWPLEX dual-treatment program includes convenient dosing procedures and ampoule-based test kits designed for simple, safe and accurate use. The program is completely compatible with both manual and automated water treatment systems.
