Operation and Maintenance of Exhaust Gas Treatment Systems
An exhaust gas system only stays compliant if it is operated and maintained properly. Nanoen carries out regular checks, replaces consumables on time and services fans and equipment, keeping the system running steadily and ready for monitoring.
- Scheduled preventive maintenance
- Timely filter bag and carbon replacement
- Operating and maintenance logbooks
- Support ahead of monitoring rounds
Common challenges for businesses
If you are facing any of the situations below, Nanoen can help.
Clogged or torn filter bags
Pressure drop rises, extraction weakens or dust passes to the stack because bags are not cleaned or replaced in time.
Saturated activated carbon
Carbon is not replaced on schedule, so odour and solvent vapours still escape even though the system is running.
Underperforming scrubber
Absorbent solution is not dosed or pH-controlled properly; nozzles and packing become clogged or scaled.
Fan failures, missing records
Fans and motors vibrate, get noisy or fail unexpectedly; no operating logbook is available for inspections.

Frequently asked questions
How often should filter bags and activated carbon be replaced?
There is no fixed interval. It depends on the type of dust or gas, concentrations and running hours. Nanoen tracks pressure drop and the actual condition of the media to recommend replacement at the right time, neither too early nor too late.
What service models are available?
Nanoen can provide monthly or quarterly scheduled maintenance, or combine it with regular operating support, depending on the size and requirements of each system.
Do you take over systems built by other contractors?
Yes. Nanoen surveys and assesses the system before takeover and proposes improvements if anything is not working as it should.
How is the O&M fee calculated?
It depends on system size, technology, maintenance frequency and the scope of consumables (filter bags, activated carbon, chemicals). Nanoen provides a quotation after an on-site survey.
