              Our free posters: Well-formatted information.

              We like to share our knowledge and our experience. Sometimes we don’t even charge for it. One example of this is our selection of posters centred on the subject of noise immission and vibration references of reciprocating compressors, screw compressors and machines in heavy industry – from gas turbines to turbo compressors to centrifugal pumps or generators.

              On request, the desired poster will be printed and mailed to you in an impressive A3-format (approx. 30 x 42 cm) free of charge. Contact Heike Nyhuis to order one. She is looking forward to your call or email.
