Service, maintenance and spare parts for energy plants

We are there when it matters.

Our work does not end with commissioning. Because we know that a plant is only successful if it still runs reliably after many years.

That is why we support our customers in the long term – with maintenance, spare parts, optimisation and personal technical advice.

When requirements change, we develop the right solution together.

Your benefitShort distances, fast support and a partner who knows your plant in the long term.

Inspection & overhaul planning

Regular inspections and forward-looking overhaul plans contribute to lasting high availability of your plant and help prevent unplanned shutdowns.

  • On-site condition analysis
  • Measurement of wear patterns
  • Detailed inspection reports & recommendations

Maintenance & servicing

Experienced Kablitz service technicians carry out planned maintenance on schedule and to a high standard – on boiler components as well as in the furnace.

  • Replacement of wear parts
  • Inspection of hydraulic drives
  • Adjustment of combustion air zones

Installation, dismantling & supervision

We handle the installation or installation management of large components worldwide: from grate systems and heat exchangers to complete boiler islands – and the dismantling of decommissioned plant components.

  • Worldwide site management
  • Dismantling of old components before conversion or replacement
  • Professional integration into existing buildings

Commissioning & optimisation

Our commissioning engineers accompany the start-up of your plant, train the operating staff and optimise combustion for maximum efficiency.

  • Dry and hot commissioning
  • Training of operating staff
  • Process fine-tuning

Conversion & modernisation (retrofit)

Changing fuel markets or stricter emission limits require adjustments. We flexibly convert existing plants to new fuels and higher efficiencies.

  • Conversion to waste wood or residues
  • Output increase of existing boilers
  • Support with emission measurements

Process engineering advice

Our process engineers advise you on fuel, combustion or plant operation – based on decades of experience in plant and power station construction.

  • Assessment of new or changing fuels
  • Combustion and emissions
  • Operation and output adjustment of existing plants

Service for third-party plants too

Benefit from more than a century of experience in thermal plant engineering. Our service and spare parts programme is also available to operators of third-party plants.

What information helps with a service or spare parts inquiry?

Include the plant type, location and affected component. Existing drawing or part numbers, the required quantity and a description of its condition help identify the requirement. For a retrofit, also describe the goal and existing technology. Missing details can be clarified in the subsequent conversation.
