Electrolyzer RefurbishmentElectrolyzers tend to degrade after long-term continuous operation, marked by rising cell voltage and declining operating efficiency. Under identical operating conditions, refurbishment becomes an economical choice when energy losses caused by equipment aging exceed renovation costs. |  |
Why refurbish an ion-membrane electrolyzer?
Controlled refurbishment restores critical electrode and cell components while helping customers avoid unnecessary expenditure on brand-new equipment.
| Uniform coating and current distribution | Automatic electrostatic spraying ensures uniform coating and even current density distribution, extending electrode service life. |
| Lower cell voltage | Our self-developed coating formula reduces cell voltage by 0.1–0.2 V under the same current density. |
| Stable operation | Refurbished electrolyzers run steadily with stable indicators and lower power consumption. |
The performance of refurbished electrolyzers is comparable to brand-new equipment.
YIANTENG applies advanced coating formulations and controlled manufacturing processes to anodes and cathodes for a wide range of membrane electrolysers, including Asahi Kasei NCH, AGC F1/F2/B1/M3, BiTAC, Bluestar (Beijing) Chemical Machinery, De Nora, INEOS BiChlor and thyssenkrupp nucera BM2.7. We also provide electrode repair and recoating services based on customer drawings and operating requirements.
