Clean and efficient

Environmental protection.

Klingspor sets industry-wide standards in terms of energy efficiency and environmentally friendly production. In its production facilities for abrasives in Haiger, the
company has installed a regenerative thermal post-combustion plant (RTNV). "The exhaust air of our production line is now twice as clean than legally required – and with 25 per cent less energy consumption," explains Dr. Steffen Neu, Chairman of the Board of Klingspor AG.
The abrasives lines are dried at over 100 degrees Celsius and the adhesives and varnishes emit gases during this process.

With the help of the RTNV, the hazardous substances in the exhaust air are burned off at about 850 degrees Celsius.

The RTNV is particularly efficient because the combustion of the flue gases creates thermal energy which is used via a heat accumulator to heat the as yet unclean air to just under 780 degrees Celsius. The additional combustion therefore requires only a small volume of natural gas – which is good for the environment and for Klingspor.
