ISO 9001:2015

ISO 9001:2015 certifies that our management system meets the globally recognized requirements for effective, transparent, and continuously improved quality management.

It applies to the following activities:
Design and manufacture of welded pressure equipment—reactors, separators, columns, heat exchangers.

During the certification process, it was demonstrated that LEFFER meets all the requirements of this standard and ensures the utmost care in the planning, implementation, and monitoring of its processes.

For us, certification means that quality is not a coincidence, but the result of systematic processes – from design and manufacturing to the final acceptance of our welded pressure equipment such as reactors, separators, columns, and heat exchangers.
