Anticorrosive Properties

TECNIUM’s modular covers are renowned for their advanced anticorrosive features. These covers exhibit remarkable resilience against the harshest gases found in wastewater treatment settings, such as sulphidric and mercaptans, thus ensuring lasting durability and optimal performance.

These anticorrosive properties render them ideal for purification plants and other installations in aggressive and corrosive environments, mitigating the risk of degradation and maintaining their integrity over time.

Easy Dismantling and Minimal Maintenance

Our covers are designed with user convenience in mind, allowing for quick and hassle-free dismantling. This feature, coupled with their almost negligible maintenance needs, makes them an attractive choice for wastewater treatment plants.

These advantages prove especially beneficial in harsh environments where the ease of maintenance and operational convenience are paramount, reducing downtime and operational hassles.

Robust and Durable Construction

The meticulous construction of our covers through advanced lamination and projection methods, reinforced with a detailed study of reticular stiffening ribs, culminates in extremely robust and sturdy structures.

These structures are capable of enduring high overloads, ensuring a long operational life and reducing the need for frequent replacements or repairs. The enhanced durability ensures that the covers can withstand the rigorous demands of wastewater treatment operations without compromising on performance.

Aesthetic Integration with the Environment

Incorporating pigmentation during the lamination phase and concluding with a final painting, our modular covers seamlessly blend with their surroundings, offering an aesthetic that is harmonious with the environment.

This thoughtful consideration of aesthetics reflects our commitment to not only functional excellence but also to the visual integration of our solutions within diverse installation sites, promoting environmental coherence and visual harmony.
