Turn difficult material into more valuable output
More uptime. More yield. Less energy.
Engineering relies on people
Anyone can ship a machine. Keeping it running through changing raw material, tightening limits and the odd 3am phone call takes people who know your plant — which is why our specialists design, build and support every Haarslev line, and stay with it long after start-up.

Haarslev capabilities help you get more profitable results
Reliable operations depend on more than equipment alone. We provide specialist engineering and service capabilities that ensure the best plant performance – all the way from planning and integration, to automation, processing optimisation and long-term support.
Project planning, systems integration and co-development
Clear requirements, early planning and well-defined interfaces reduce uncertainty and risk, and make sure the setup reflects your ideas and matches your needs from the start.
Material handling and in-plant transport
Material that moves safely, cleanly, reliably and efficiently through the plant supports stable processing and higher uptime, both upstream and downstream.
Reducing particle size
Controlled size reduction that improves your separation steps, makes drying more effective and adds stability to downstream operations.
Mechanical and thermal separation and dewatering
Efficient phase separation using the technologies (whether mechanical or thermal) best suited to your particular processing requirements and output goals.
Automation and control of key processes
Integrated automation, control and monitoring for repeatable, energy-efficient processing you and your team can rely on day after day.
Dealing with odours and emissions
Integrated monitoring and control to reduce odours and emissions, helping you manage nuisance, protect the plant’s surroundings and support your ESG reporting.
Life cycle support
Ongoing service and support that protects performance and uptime across the service life of your equipment, and extends that life through refurbishment and planned service programmes.
Commissioning, training and documentation
Well-planned commissioning, training and documentation so your new setup moves smoothly into day-to-day operation, and your team knows how to run and troubleshoot it confidently.
What Haarslev helps you do better
Haarslev engineering, capabilities and know-how pave the way to better control, steadier output and fewer expensive surprises.
Haarslev enables you to turn often-difficult organic material into revenue-earning outputs that are more consistent and easier to manage.
The most effective improvements usually come from carefully considering the parts of the process that decide performance, day after day:
- More stable day-to-day runningDeal with variable inputs and processing conditions effectively, using processing equipment, control systems and support configured to your exact requirements.
- Better control over costsImprove yield, energy efficiency and maintenance predictability in the processing steps that impact your profit margins most.
- Lower operational riskStrengthen reliability, safety and service response, because downtime gets expensive.
- Stronger compliance capabilitiesSupport cleaner, more responsible operations, with more comprehensive monitoring and documentation – making it easier to comply with accelerating regulatory requirements.
- Hardware setups targeted at profitabilityEliminate bottlenecks, increase revenue-earning uptime, integrate specialist capabilities and extend the service life of your key equipment.
More consistent, more reliable day-to-day running.

to maximise plant performance
Keep your plant performance stable, avoid revenue-denting downtime and get practical support that helps you with how your plant actually runs.
Service and troubleshooting
When performance starts falling off, or something goes wrong, you probably need a lot more than just a quick fix. You need to identify the cause, how best to correct it, and where to get the best help – fast.
- Remote and on-site support
- Troubleshooting with practical corrective actions
- Clear recommendations to restore stability and reduce repeat issues
Preventive maintenance
Last-minute searches for a remedy aren’t effective – and are likely to result in costly downtime. Turn maintenance and inspections into planned, budgetable preventive action focused on uptime.
- Service planning aligned with your operation
- Inspections and condition checks with clear priorities
- Practical guidance to keep performance stable between visits
Upgrades and refurbishment
At some point, things like downtime, equipment wear, capacity limits or new requirements will inevitably start blocking your plant’s capabilities. That’s when targeted upgrades and carefully planned refurbishment help you restore performance, without you needing big investments in new equipment.
- Upgrade options for wear, capacity and efficiency needs
- Refurbishment planning to restore reliability
- Faster routes back to operation where exchange options apply

Proven experience
Growing demand for sludge drying at scale
2025 saw Haarslev disc dryers being selected for sludge drying and incineration projects across China and south-east Asia. From four semi-drying lines for a 150-tonnes-per-day facility in Singapore to installations handling 700 and 800 tonnes per day in China, the requirement was the same: reliable, energy-efficient drying at scale.
