Our clients

De Kleijn Energy Consultants & Engineers is located in The Netherlands. However, an important part of our work is done for companies in foreign countries.

We mainly work for industrial companies, especially for the food processing industry, but we also executed many projects in other industries, like waste water treatment plants, energy production plants, metalworking industry and plastics industry. Besides industrial companies we also have worked on several projects for small to medium-sized companies and governmental institutions.
