Diethyl Hydroxylamine (DEHA) is an organic compound, mainly used as an oxygen scavenger in water treatments for controlling corrosion in boilers very effectively. It reacts with oxygen to form acetates, nitrogen, and water. It is non-toxic, providing good protection against corrosion at the same time. Due to its capability of inhibiting polymerization in the gas phase, DEHA is finding use as an in-process inhibitor for the production of styrene, divinylbenzene, butadiene, and other monomers. In the boiler, it encapsulates metal surfaces and then passes out of the boiler with steam, passing through a metal passivating agent in the return line system.

Key Features and Benefits:

• Completely organic compound
• Volatile - Does not add TDS to blow down water
• Metal passivator and rust converter
• Effective condensate line treatment and pH booster
• Non-toxic and more safe than hydrazine and carbohydrazide based chemicals
• Compatible with other treatment chemicals
• Returns to the feed line with the condensate return so passivates total system
• High rate of reaction with oxygen compared with other oxygen scavengers
• It offers a vapor-liquid distribution ratio of 1.3 and thus distributes all along the condensate circuit, ensuring a total control of corrosion
• Single treatment for total corrosion control in boiler

In boilers, mineral deposits and scale buildup reduce heat transfer efficiency, increase fuel consumption, and lead to frequent downtime for cleaning and repairs.

Boiler Antiscalant is a high-performance treatment designed to prevent scale formation and dissolve existing deposits in boiler systems. It works by inhibiting the crystallization of scale-forming minerals, ensuring efficient heat transfer and extending the life of the boiler. Suitable for a wide range of water conditions, this antiscalant reduces energy costs, minimizes maintenance, and keeps your boiler running at optimal performance. It’s the ideal solution for maintaining efficiency and reliability in industrial and commercial boiler operations

In systems like boilers and feedwater lines, dissolved oxygen accelerates corrosion, leading to equipment damage, increased maintenance, and reduced efficiency. Chemtex's Catalyzed Oxygen Scavenger is a liquid formulation based on sodium sulfite and bisulfite, designed to react instantly with dissolved oxygen. This reaction converts the oxygen into sodium bisulfate, effectively removing it from the feedwater while significantly reducing alkalinity. This dual action protects metal surfaces, enhances system efficiency, and ensures optimal water chemistry, making it an ideal solution for maintaining the longevity and performance of industrial systems.
