Humidity Problems in Switchgear Rooms | Bry-Air

Dehumidifying the switchgear room ensures that the insulating components do not fail and power outages are prevented due to high humidity. The simplest and the most cost-effective method to control humidity is to install a Bry-Air Dehumidifier. Irrespective of the make of switchgear either imported or indigenous like SIEMENS/ABB or any switchgear, e.g. Bulk Oil/Vacuum/sf 6, dehumidification is needed for all.
