RAVO is the inventor of the compact street sweeper and is committed to building the best sweeper in the world. RAVO stands for excellent quality, reliability and durability. That is what we expect from our partners. To go through the ISO 14001:2015 certification process we selected QMSI. QMSI performed this process satisfactorily and appropriately. After obtaining the certificate, we now continue with the training of our internal auditors by QMSI. QMSI thinks along with us, and is a flexible organization with also a great response to our correspondence. Altogether QMSI has been an excellent partner for RAVO.
