Klein Technical Solutions has established itself as a leading company in the development and building of sludge thickening, dewatering and drying plants worldwide.

The roots of Klein are going back until 1905 and in the meantime KLEIN established itself as a specialist in sludge treatment on the market – one key milestone was the development of the first Belt-Filter-Press (1966).

In 1998, the Environmental Engineering sector became independent. Since it’s independence, the Environmental Engineering sector of Klein developed and launched the Low-Temperature-Drying processes Pro-Dry®, Compact-Dry and Combi-Dry. This led to a further extension of the market position, the enlargement of the product portfolio and enabled a more flexible reaction to customers’ request.

Our portfolio comprises all services for the successful realization of your project, starting from first planning, including design and realisation as well as tailor-made customer service packages, for all projects from small standard systems up to sophisticated and individually planned water treatment plants. Our substantiated know how in sludge treatment is based on long term experience. 

Even beyond the successful start up of the plant we are at your disposal. We can offer regular maintenances, spare parts and consumables management or complete operation & maintenance packages - everything adapted to your special needs.

Our experience is based on more than 4,000 successfully installed plants in differenct applications all over the world:

  • Belt-Thickener with a throughput of 9 m³/h up to 150 m³/h, Belt-Filter-Presses with a throughput of 6 m³/h up to 30 m³/h and Dryer with a water evaporation capacity of 300 kg/h up to 8,000 kg/h.
  • For excess sludge, brewery flotate sludge, primary sludge, anaerob and aerob stabilized sludge, for dairy sludge, industry sludge, sinter sludge, paper sludge and digested sludge, fermented substrates and wood chips. 
  • In countries like: Egypt, China, France, Great Britain, Ireland, Italy, Croatia, Lithuania, Luxembourg, Mauritius, New Zealand, the Netherlands, Austria, Oman, Poland, Russia, Saudi Arabia, Switzerland, Slovenia, Ukraine, Uzbekistan etc.
Substantiated information on rules and regulations, requirements of production processes and the awareness of environmental aspects are as self-evident to us as the compliance with international standards. Whether you need a system for dewatering or drying we will elaborate a state-of-the-art solution, tailor-made to your needs.

The roots of SÜLZLE KLEIN date back to the 1966. The most important milestone in the company history was the development of its first Belt-Filter-Press in 1966. This was followed by the development of a Gravity-Belt-Thickener in 1982 and the first Belt-Dryer in 1988. The company increased its presence in the market again with the development and introduction of the Pro-Dry® low-temperature drying system. Further expanding our product portfolio with other developments, such as the Compact-Dry and the Conti-Dry, we are now able to provide a more flexible response to the needs of our customers.

Driven forward by the SÜLZLE GROUP membership, SÜLZLE KLEIN can supply complete solutions, making it a specialist in the market for sludge solutions.

We provide planning, engineering and design services from a single source. Once your plant is commissioned, we can also take over maintenance, servicing and spare-parts and wearing-parts management or support you during operation if desired.

SÜLZLE KLEIN GmbH is a global leader in the development and implementation of thickening, dewatering, and drying systems. Since its founding in 1905, KLEIN has established itself in the marketplace, step by step, as a specialist for sludge solutions.

The first Belt Filter Press was developed in 1966, setting one of the most important milestones in the history of KLEIN. In 1998 the Environmental Engineering group became an independent company. The market position was expanded due to the development and introduction of the Pro-Dry low-temperature drying line. Compact-Dry and Conti-Dry further extend the product portfolio and allow faster response to customer requests.
