Corrosion Control Unit
Corrosion has several negative effects. It can result in failure of the installation with potentially dangerous situations as a consequence. When considering the corrosion caused by sewage gases, H2S is one of the mayor sources of corrosion. In sewage treatment plants, copper is often observed to turn black (H2S) or green (NH3). The corroded metals can result in sparking and failure of the switching gear. Obviously, the sensitive printing boards of high valued equipment like PLC, VFD and PC’s are also affected by corrosion.
Besides corrosion, the electrical switching gear can also be negatively affected by dust . Because of dust, microcontacts are not closing and opening properly which can result in misfunctioning or dangerous sparking.
To prevent the fall-out of the electrical cabinet, Ipec introduces a corrosion control system existing out of:
- A dust filtration system (coarse filter in combination with absolute filter)
- A H2S removing activated carbon system, removing the last traces of H2S up to ppb levels, guaranteeing the long life time of the electrical components.
The sizing of the corrosion control unit depends on the size of the cabinet, the heat dissipation and the set-up of the air conditioning. Ipec can provide a customized solution, taking all these parameters into account.
