Passivation Systems

Passivation consoles provide a controlled and efficient solution for treating stainless steel and other metals to enhance their resistance to corrosion. Using either nitric acid or citric acid chemistries, these systems remove free iron and surface impurities, forming a durable, passive oxide layer that protects against oxidation and environmental damage.

Nitric acid-based passivation offers robust performance for demanding applications, while citric acid provides a safer, environmentally friendly alternative with reduced toxicity and simpler waste management. Both options deliver consistent, high-quality results, meeting stringent industry standards in aerospace, medical, manufacturing, and other sectors.

A key consideration in passivation systems is the integration of robust exhaust solutions. Effective exhaust systems are essential for safely managing fumes generated during the process, particularly with nitric acid, which can release nitrogen oxides (NOx) and other potentially hazardous emissions. Proper ventilation ensures a safe working environment and compliance with regulatory requirements.

Modern passivation consoles combine precision controls for temperature, timing, and chemical concentrations with advanced exhaust management. These features make them reliable and adaptable solutions for small-scale operations and high-throughput production lines, ensuring superior metal performance, safety, and environmental responsibility.
