Contract surface treatment and plant engineering under one roof

The plus in ELTROPULS: Our sister company ELTROPULS Anlagenbau GmbH works under the same roof. This provides you with maximum production reliability and strengthens your competitive position. After all:

  • The plant engineers can immediately resolve any faults during contract surface treatment. Spare parts and service are available around the clock.
    We can draw on a large number of treatment systems. No time or quality losses arise as a result.
  • Series production is our everyday business. Every plant can be adjusted precisely to the surface treatment you require.
  • Want to use plasma-nitriding in series production in your own operation but don’t yet have any experience with it? While your nitriding plant is being built next door, we start up your series production on our ELTROPULS plasma plant. Once your new plasma nitriding plant has been delivered, you can avail of fully automated manufacturing at the touch of a button.

Protecting the environment

Currently, plasma nitriding is the most environmentally friendly nitriding process. Neither the substances used nor those developing during the process are harmful to humans or nature. Our patented nitriding process means minimal pollution, thereby setting new standards. This environmentally conscious, energy efficient and resource-conserving approach is also documented in our certification according to DIN EN ISO 14001, with which we commit ourselves to continuously improving our environmental performance.
