Maintenance and troubleshooting of ABB SCC-K converter

Installation environment and long-term shutdown strategy

In order to extend the lifespan of the converter, on-site environmental control cannot be ignored.

Installation location: SCC-K is designed for 19 inch rack or wall mounted installation. Regardless of the method, at least 1 height unit (1U) of heat dissipation space must be reserved directly above it. The equipment should be kept away from direct sunlight, ovens, or high dust and corrosive environments. The ambient temperature should be controlled between+10 ° C and+50 ° C, and the annual average relative humidity should be ≤ 75%.

Short term shutdown (Stand by): In case of a brief pause in production, in order to avoid unnecessary catalyst consumption and ensure that it can be restored to use at any time, it is recommended to lower the catalyst temperature to about 100 ° C during the short-term shutdown (standby mode).

Long term shutdown: If the equipment is not in use for a long time, it is recommended to use inert gas or air to blow the inside of the converter at room temperature to remove residual corrosive gases and prevent condensation and acid corrosion of internal components.

Packaging and transportation: If it is necessary to return to the factory for maintenance or relocation, the thermal converter must first remove the quartz glass reaction tube, install it in a dedicated transportation protective cover, and fix it on the chassis bracket. Shock proof foam shall be used for the outer package, and it shall be marked with "Fragile goods, upright transportation".
