DEHN and Environment

DEHN protects. This guiding principle also applies to our commitment to environmental protection. Since 2000 we have had an environmental management system in place which is certified according to DIN EN ISO 14001.


Professional and environmentally compatible recycling of used devices, spent batteries and packaging material is important to us and reduces the environmental impact to a minimum.

Used devices

The WEEE2 directive (RL 2012/19/EU) regulates the return and recycling of used electrical and electronic equipment in order to recover valuable raw materials. This applies to all DEHN products which are marked with the symbol on the right. In individual cases (small product dimensions) the symbol is only printed in the installation instructions / operating instructions.

Our WEEE registration no. is: DE 69459855


Please note the following differentiation with regard to used devices:

B2C products – Business to Consumer

Some of our devices are used in private households or comparable applications and may not be disposed of in the normal household waste. They must be returned to public collection points (e.g. municipal recycling centres).

B2B products – Business to Business

These devices have been used in the commercial sector and again may not be disposed of in the normal household waste. They should be professionally recycled.

Used batteries

Used batteries may contain harmful substances that could damage the environment and present a health risk. For this reason, they should not be disposed of with the normal household waste. Collecting them separately also makes it possible to recover valuable raw materials from the used batteries.

Please return used batteries or accumulators to suitable collection facilities, e.g. collection boxes of the GRS foundation (Common Recycling System of Batteries). For safety reasons, please tape up the poles of lithium batteries to avoid short circuits.

Product and transport packaging

We collaborate with the company Interseroh Dienstleistungs GmbH with regard to the return and recycling of used packaging material.

Product conformity

Of course, we also feel responsible for our products during their service life. For this reason, the vast majority of DEHN products comply with substance restrictions above and beyond the legal requirements.


The RoHS2 directive (2011/65/EU) states limit values for hazardous substances in electrical and electronic equipment. Currently, these are lead, cadmium, mercury, chromium (VI), polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE).

We endeavour to adhere to these substance limitations - in part through recourse to exemptions - for almost all DEHN products, although only a certain part of our product portfolio actually falls under the scope of the RoHS2 directive. In the case of a few products there is a function-related increased lead requirement (e.g. lead ball coupling for earth rods or moulded gunmetal parts).

We are aware of the (EU) requirements in the amendment (delegated directive 2015/863) which includes the four plasticisers Bis(2-ethylhexyl)phthalate (DEHP), Butyl benzyl phthalate (BBP), Dibutyl phthalate (DBP) and Diisobutyl phthalate (DIBP). We are already working on the timely implementation of the stipulations. The implementation deadline for DEHN as a manufacturer of monitoring and control instruments is 22 July 2021.

Information on compliance with the RoHS2 directive should be taken from the EU declaration of conformity for those products which fall under the scope of application.

For all other products, you can contact us at the following e-mail address stating the part number:


Besides dealing with the regulation of all chemicals in the European Union, the REACH regulation ((EC) No. 1907/2006) also includes requirements on products:

  • Duty to provide information on substances of very high concern (SVHC) and substances subject to authorisation (Annex XIV)
  • Restrictions, among other things, of the use of certain substances in selected applications (Annex XVII)

Further information on those substances in DEHN products which are on the candidate list for substances of very high concern (SVHC) can be found in the following statement:

Please note: If products comply with RoHS2 under recourse to exemptions concerning lead, you are nonetheless obligated to provide information on SVHCs.
