Profile: Electronsystem MD specializes in developing and producing a broad range of products for use on medium (MV) and high voltage (HV) switchgear and devices. The gas density controller (GDC) has unique bellows configuration for the reference chamber. It also has high resolution and can be easily configured to match applications, which bodes well with various industries of production. The humidity absorber prevents moisture from reaching critical limits in the SF6 gas which is necessary for High voltage switchgears? smooth working. The humidity absorber prevents damage to the gear which may otherwise occur due to SF6 and moisture exposure to a high amount of heat.
