Over the last 20 years more than 140,000 SCR compressors have been installed worldwide, often subjected to the harshest operating conditions from Scandinavian frost, through desert dust, to high temperatures and extreme humidity in Latin America and Indochina. Thanks to state-of-the-art components and a precise production control system, SCR compressors have passed the toughest tests in industry, energy and other areas with the need for highly efficient compressed air production.
