Additional Binder Services 

  • Commissioning and On-Site Service Our skilled service personnel are available to assist you with the commissioning of our products on-site. This includes training for operational staff in the use of our products, as well as providing further guidance on operation and maintenance.

    For optimal operation of the VACOMASS® system, fine-tuning of control parameters is usually required after delivery, installation and commissioning. Depending on specific plant conditions, preset parameters will be reviewed and adjusted during the initial stages of operation.
  • Device Inspection The inspection of all devices can be carried out either at the main facility in Ulm or on-site, depending on the product type. Our experienced service personnel typically carry the appropriate spare and wear parts. Please note that devices Installed in EX can only be inspected in Ulm.
  • Verification of the Calibration/ Recalibration Gas flow meter of the COMBIMASS® series are generally maintenance-free. However, under certain circumstances (e.g., measurements in corrosive or abrasive media) or in specific projects (CDM, high accuracy requirements, etc.), it may be advisable to periodically check the calibration of the sensors.

    The intervals should be chosen to ensure that there are no changes in the measuring equipment that would negatively impact the measurement task until the calibration or recalibration is performed.

    The choice of intervals is at the discretion of the user but may also be dictated by standards, guidelines, or legal requirements. Gas analysis devices of the COMBIMASS® GA-s or GA-m series require regular recalibration to maintain measurement accuracy over longer periods. The intervals can vary from monthly to annually, depending on measurement frequency, gas component concentrations, and accuracy requirements.
  • Maintenance for Replacement of Wear Parts or Assemblies Regular maintenance and replacement of wear parts are necessary for COMBIMASS® series gas analysis devices and measurement systems to maintain measurement accuracy at a consistently high level. Special maintenance contracts offer regular replacement of wear parts and the provision of replacement devices during maintenance. Without such a contract, the maintenance interval is the responsibility of the user.
  • Repair If repair is required, we offer fast and professional service. Special fittings and/or ATEX-certified devices can only be inspected and repaired by the manufacturer (INSTRUM, FAIRCHILD, CASHCO, etc.). In such cases, we recommend obtaining a cost estimate for your planning needs.
  • Training, Seminars, and Lectures We regularly participate in industry events such as seminars or conferences and give lectures on relevant topics. Furthermore, we offer training sessions for your operational personnel on the use and maintenance of our products. Please do not hesitate to contact us if you have any questions.
