Rotor Deterioration Inspection and Analysis
We recommend regular diagnostic checks of the honeycomb rotor.
We will propose analysis items tailored to your operating environment.
Benefits of Regular Diagnosis
1. Prevention of sudden performance drop and potential issues
2. Optimize for changes in operating conditions and predict the timing of replacement
3. Budgeting and cost reduction through planned replacements
Target Products
- Dehumidifying rotor
- VOC Concentrator rotor
Disadvantages of Rotor Deterioration
- Trouble due to performance degradation (production stoppage, yield deterioration, etc.)
- Load on fan and other ancillary equipment due to clogging
- Accumulation of high boiling point substances leading to fire and burning
We recommend rotor deterioration inspections not only for maintaining performance but also for ensuring safe use.
Factors Contributing to Rotor Deterioration
- Aging
- Condition of processed air
- Inclusion of degrading substances
- Effects of installation environment, etc.
