Checklist: Verifying Dryer Reclaiming Service Terms
Use this checklist to verify dryer reclamation service terms. It covers desiccant replacement scope, regeneration methods, downtime windows, and cost transparency to prevent unexpected air treatment maintenance contract issues.
- Define whether the service covers full desiccant replacement or only regeneration.
- Verify that regeneration methods match your equipment rating and load profile.
- Confirm the service contract includes a defined downtime window and a clear cost structure.
- Check that the provider documents the as-found condition and the reclamation outcome.
What does dryer reclamation actually cover?
Dryer reclamation often gets bundled into a single line item on a quote. This makes it easy to miss what is included and what is not. Before you sign a maintenance contract, break the term down into physical actions.
The core action is removing used desiccant from the dryer vessel. The service may then include regeneration of that same desiccant, or it may include replacement with new desiccant. These are two different scopes with very different costs.
Some providers offer only the removal and hauling of the used material. Others include the full cycle: removal, regeneration, reinstallation, and testing. Still others sell a replacement package that bundles new desiccant media with labor.
The distinction matters because the cost gap between these options can be significant. If the quote says “reclamation,” ask for the physical steps in writing. A service that includes only removal and hauling is not the same as a service that restores the dryer to full capacity.
A common mistake is assuming that “reclamation” means the provider handles everything. In practice, the provider may hand back a bag of regenerated desiccant and let your team handle the installation. If you do not want that responsibility, state it in the work order.
Which regeneration method fits your equipment?
Not all desiccant regeneration processes are equivalent. The method chosen affects the capacity of the material after reclamation and the time required to return the dryer to service.
Thermal regeneration uses heat to drive out moisture from the desiccant. This method is common for high-capacity industrial dryers. It requires a dedicated regeneration system or a compatible heat source. The process can take hours, depending on the vessel size and the moisture load.
Electrostatic regeneration uses an electrical field to pull moisture from the desiccant. This method is faster in some cases and uses less energy than thermal regeneration. It is often used in smaller or medium-sized vessels where the heat source is not readily available.
The key point is that the method must match your dryer design. If a dryer is rated for a specific desiccant type and a specific regeneration profile, using a mismatched method can reduce the material lifetime. Ask the provider to confirm that their reclamation process is compatible with the desiccant currently in the vessel and the vessel manufacturer’s specifications.
If the provider does not specify the method, that is a red flag. A competent service will know the method because it affects their equipment requirements and the service window.
How do you verify the cost structure?
The quote for dryer reclamation should have a clear cost breakdown. If the quote is a single number, ask for the line items.
The cost should show at least three components: labor, material, and regeneration. Labor covers the removal and reinstallation of the desiccant. Material covers the desiccant itself, whether it is being regenerated or replaced. Regeneration covers the energy and processing cost of the reclamation method.
Some quotes include a travel or mobilization fee. This is separate from the service cost and should be listed. If it is not listed, ask. A hidden mobilization fee can add a meaningful amount to the total cost, especially for sites that are not in a high-density industrial area.
Also check for any exclusions. Does the quote include pressure testing of the vessel after reinstallation? Does it include a dewpoint verification test? Does it include disposal of the used desiccant if the provider decides not to regenerate it?
A clear cost structure is not just about price. It is about predictability. If you can see the line items, you can compare quotes from different providers and you can spot when a scope change happens. If the provider changes the desiccant type or the regeneration method, the cost should change in a way you can trace back to the line item.
What downtime window should you expect?
The downtime window is the time from the start of the service to the point where the dryer is back in service and verified. This is not just the time the technician is on site. It includes the time required for the regeneration process to complete.
A typical reclamation service can take anywhere from a few hours to a full day, depending on the vessel size and the regeneration method. Thermal regeneration often takes longer than electrostatic regeneration. A large vessel with a high moisture load will take longer than a small vessel with a low load.
The service contract should state a maximum downtime window. If the provider says “about half a day,” ask for a specific number of hours. “About” is not a contract term.
If your operation cannot tolerate a long downtime window, discuss the options. Some providers can run a partial reclamation, where only one side of a dual-vessel dryer is serviced at a time. This keeps the other side in service while the first side is reprocessed. This is not always possible, but it is worth asking.
If the provider does not specify a downtime window, you are taking on the risk of an extended outage. That risk is not yours to carry if you are paying for a service.
How do you verify the service documentation?
The service report is your record of what was done. Without it, you cannot verify the quality of the reclamation or defend the decision in an audit.
The report should include the date and time of the service, the vessel identification, the desiccant type and quantity, and the regeneration method used. It should also include the operator’s name and a signature.
Most importantly, the report should include the as-found and as-left conditions. The as-found condition is the dewpoint or moisture level measured before the service. The as-left condition is the dewpoint or moisture level measured after the service. This gives you a direct measure of the service effectiveness.
If the provider does not provide an as-found and as-left report, that is a red flag. It means you cannot verify that the service was performed to standard.
Keep a copy of the report for each service. Over time, these reports become a trend record. If the dewpoint after service is drifting upward over several quarters, that is a signal that the desiccant is degrading faster than expected or that the regeneration process is not fully effective.
Red flags to watch for
Some terms in a dryer reclamation quote are easy to miss but have a large impact on cost and service quality.
A quote that does not specify the desiccant type is a red flag. Different desiccants have different capacities and regeneration profiles. If the provider does not know or does not care, the service may not be effective.
A quote that does not specify the regeneration method is a red flag. The method determines the service window and the material lifetime.
A quote that does not include a downtime window is a red flag. You need a defined maximum time to plan your production schedule.
A quote that does not include an as-found and as-left report is a red flag. Without it, you cannot verify the service quality.
A quote that bundles reclamation with other services without a clear breakdown is a red flag. It makes it hard to compare quotes and to trace cost changes over time.
How to structure the service contract
Once you have verified the scope, cost, and terms, put them in writing. The service contract should be a short document, not a narrative.
The contract should state the service scope in plain language. For example: “Provider will remove, regenerate, and reinstall desiccant in dryer vessel DRY-01. Regeneration method is thermal. Maximum downtime window is 8 hours. Service report will include as-found and as-left dewpoint readings.”
The contract should state the cost structure. If the quote is a fixed price, say so. If the quote is an hourly rate, say so. If there are variable costs, list them.
The contract should state the downtime window. If the provider exceeds the window, there should be a consequence or a review trigger.
The contract should state the documentation requirement. The provider must deliver a service report within a defined time after the service is complete.
A clear contract is not a formality. It is the tool you use to hold the provider accountable and to compare performance over time.
How to compare provider quotes
When you have multiple quotes, do not just compare the total price. Compare the scope.
Two quotes can look similar on the surface but be very different in what they include. One quote may cover removal and regeneration. Another may cover removal and replacement. The cost difference reflects the different scope.
Use the line items to compare. If Provider A charges $500 for labor and $300 for material, and Provider B charges $600 for labor and $200 for material, the total is the same but the breakdown is different. The breakdown tells you something about the provider’s cost structure and their risk profile.
Also compare the service window. If Provider A offers a 6-hour window and Provider B offers a 10-hour window, that is a meaningful difference for your production plan.
Finally, compare the documentation. If Provider A provides a full as-found and as-left report and Provider B does not, that is a quality difference.
Frequently asked questions
Can I regenerate desiccant on-site?
It depends on the dryer design and the regeneration method. Thermal regeneration usually requires a dedicated heat source and a compatible system. Electrostatic regeneration is easier to do on-site but still requires specific equipment.
How often should desiccant be reclaimed?
It depends on the load profile, the desiccant type, and the operating conditions. A high-load environment with high humidity will require more frequent reclamation than a low-load environment. The service report trend over time will tell you when to schedule the next reclamation.
What is the difference between reclamation and replacement?
Reclamation is the process of restoring used desiccant to service. Replacement is the process of removing the used desiccant and installing new desiccant. Reclamation is usually cheaper but may have a shorter material lifetime. Replacement is more expensive but resets the material lifetime.
Do I need to test the dewpoint after reclamation?
Yes. The service report should include an as-left dewpoint reading. This is the direct measure of service effectiveness. If the provider does not provide this reading, you should perform it yourself.
What if the provider does not specify the regeneration method?
Ask them to specify it in writing. If they cannot or will not, that is a red flag. The method determines the service window and the material lifetime, and it should be a defined part of the service scope.
