After Sales Service
Reliable operation.
Better energy performance.
Technical service and energy optimisation for heat exchangers, process air systems and heat recovery installations. We help you keep equipment in good condition and improve its performance as operating conditions change.
Two priorities. One service partner.
Protect the equipment.
Improve the way it runs.
01
Technical service & reliability
Keep your installation fit for its duty, with support based on its design, condition and maintenance history.
- Inspections and functional checks
- Troubleshooting, wear and fouling assessment
- Spare parts, repairs and refurbishment coordination
- Support for shutdowns, restarts and recommissioning
02
Energy & operating performance
Review how the equipment performs in production and where adjustments can improve energy use and operating costs.
- Performance review after commissioning
- Periodic analysis of real operating conditions
- Review of controls, part-load and bypass operation
- Assessment of cleaning effectiveness and heat recovery potential
The service scope is agreed for your installation, operating requirements and in-house maintenance resources.
After start-up. During operation. After change.
Commissioning is the beginning
An installation can run reliably while using more energy than necessary. Production schedules, product mix, flow rates, temperature levels and heat demand evolve. Regular reviews help keep equipment settings aligned with the actual process.
01
After commissioning
Review representative production data once the plant has settled into operation. Compare actual duty with the design and establish a useful performance reference.
02
At regular intervals
Check performance trends, cleaning effectiveness and operating costs. Agree the review frequency around energy relevance, fouling behaviour and available maintenance windows.
03
When conditions change
Reassess operation after process changes, extended shutdowns or modifications. Recommissioning checks functions, settings and performance against the current requirements.
Engineering in practice
Find the causes behind lost performance
Our engineers combine equipment knowledge with thermodynamic analysis and energy consulting. Typical review questions include:
| Review area | What we investigate | Possible next step |
|---|---|---|
| Fouling & cleaning | How do heat transfer and pressure drop develop between cleaning cycles? How much performance does cleaning restore? | Review cleaning effectiveness and intervals within the site’s hygiene and process requirements. |
| Part-load & bypass | When is heat recovery bypassed or the equipment operating away from its intended duty? | Review operating sequences and settings with the plant team to reduce avoidable energy losses. |
| Changed heat demand | Do available waste heat and useful heat demand still coincide in temperature and timing? | Assess control adjustments, additional heat users or a broader heat recovery / Pinch analysis. |
| Filters & process air | Do filter condition, pressure loss, air flow and temperature or humidity settings still suit the process? | Plan periodic filter replacement and review operating settings to maintain process conditions and limit avoidable fan energy use. |
Compare like with like
Lower recovered heat output does not automatically indicate a fault. Inlet temperatures, flow rates and production conditions may have changed. We assess performance against a relevant reference and check data quality before recommending action.
Steam systems & equipment life
Prevent steam hammer.
Document correct operation.
Condensate accumulation and unstable steam operation can cause steam hammer (water hammer in steam systems), especially during start-up, part-load operation and load changes. We review steam supply, controls and condensate removal to identify causes and reduce the risk of premature equipment damage.
Check the conditions that matter
- Steam pressure, control behaviour and condensate backpressure.
- Drainage and steam trap operation during start-up, low load and load changes.
- Targeted pressure and temperature measurements, with suitable instrumentation and recording resolution for brief transients.
Evidence for warranty extensions
Where measurements confirm correct operation and no steam hammer is detected in the assessed operating states, this evidence — together with documented maintenance and recommissioning — can often enable a warranty extension for suitable Anytherm equipment.
The measurement report records the operating states and period assessed. Warranty eligibility, scope, duration and service requirements are agreed individually.
From operating data to action
Start with the data
already in your plant.
We first review the data available from your process control system or historian, together with operating and maintenance records. Equipment-specific measurement points or a temporary measurement campaign can fill important gaps.
Periodic data exports can provide a practical starting point. Data access, analysis frequency and any additional measurements are agreed with your team.
A focused performance review
- Agree the operating question and relevant reference conditions.
- Check temperature, pressure, flow, humidity and operating-state data as needed for the equipment.
- Interpret trends alongside production, cleaning and maintenance events.
- Deliver prioritised actions and review their effect after implementation.
Anytherm INSIGHT
This engineering-led approach also informs our development of INSIGHT for structured performance assessment and optimisation of thermal systems.
Heat recovery after commissioning
Get more value from
the heat you already recover.
Reviews after commissioning and periodic optimisation can reveal substantial energy-saving potential in existing heat recovery systems. Control settings, bypass operation, fouling and changing production conditions all influence how much useful heat reaches the process.
When a Pinch analysis is the next step
If recovered heat remains unused or no longer matches the required temperature or timing, a broader heat recovery / Pinch analysis can identify better ways to use it. We reassess heat sources and users across the site, including existing equipment, additional heat users and potential heat pump integration.
The result is a prioritised set of operating improvements and retrofit options, assessed for energy savings, implementation cost and payback.
From our work with Nestlé
Nearly 25%
Natural gas reduction potential identified
At a major food production site, our Pinch-based study assessed heat integration across processes, utilities and existing exhaust air heat recovery systems.
This is identified site-level potential from a comprehensive heat integration study, including measures beyond routine operating adjustments. Actual savings depend on the measures implemented.
The commercial perspective
Make improvements earn their place
We assess the operating benefit alongside the effort and cost of a measure. This gives your team a basis for deciding what to adjust now, what to include in the next shutdown and where further investment is worthwhile.
Energy & cost
Translate useful energy savings into annual value using representative operating hours and energy costs. Account for changes in auxiliary electricity use, such as fans and pumps.
Maintenance & availability
Consider cleaning effort, spare parts, service cost and production interruptions. Plan actions around process requirements and maintenance windows.
Retrofit & investment
Compare operating adjustments with refurbishment, extensions or replacement. Assess expected savings, implementation cost and payback for the specific application.
Where the review points beyond one unit, we can extend the assessment through energy consulting and heat recovery / Pinch analysis.
Support matched to your plant
A review today. A plan for the years ahead.
Start with a specific operating issue or discuss a longer-term service arrangement. We define the scope, responsibilities, review intervals and commercial terms with you.
Targeted service visit
An inspection, troubleshooting assignment or recommissioning visit focused on the equipment and the issue at hand.
Performance review
A defined assessment of operating data, supported by on-site checks or additional measurements where needed, with recommendations for the next steps.
Ongoing service arrangement
An individually agreed combination of inspections, periodic energy reviews, technical support and follow-up on improvement measures.
Keep everyday maintenance in the plan
Periodic filter replacement, cleaning, seal checks and other routine tasks can form part of an agreed maintenance plan. We define intervals and responsibilities with your team, taking account of equipment condition, hygiene requirements and plant location. Work can be coordinated with your own maintenance staff or local service providers; Anytherm’s on-site involvement is agreed for each assignment.
Practical questions
Planning your next service step
Which equipment can you support?
Our service scope covers heat exchangers and recuperators, exhaust air and flue gas heat recovery, process air systems, steam air heaters and desiccant dehumidifiers. We also review service needs for Anytherm process equipment and OEM assemblies. For third-party installations, we first assess the technical scope and available documentation.
Do we need a new monitoring system?
The starting point is the information already available in your plant. We review whether existing process data and periodic exports are sufficient. Additional measurement points are proposed where they answer a specific technical or energy-performance question. For steam hammer assessments, the instruments and recording resolution must be suited to detecting brief events; routine trend exports may be insufficient.
What will we receive from a performance review?
Depending on the agreed scope: a documented assessment of operating conditions, identified deviations, prioritised measures and an estimate of their energy and commercial implications. Assumptions and data limitations are made clear. A follow-up review can help verify the effect of implemented measures.
What should we send with a service enquiry?
The equipment or project reference, a short description of the issue or objective, current operating conditions and any recent changes. Available trend data, inspection or maintenance records and photographs help us prepare the next step.
