GOBI77A
Automatic Dehydrator, 230 VAC

Rev : A | Rev date : 15 Nov 2025

The GOBI77 Automatic Pressurization Dehydrator is designed to protect air dielectric cable systems up to 3600 l. 
The dehydrator includes a self contained completely automated air drying system that utilizes a pressure swing moisture absorption cycle to provide pressurized dry air. This eliminates the need for replacement or manual reactivation of the desiccant and together with the LAN remote monitoring makes the GOBI77 dehydrator ideal for unattended operation at even remote sites.
The diaphragm pumps start at 25 kPa and stop pumping 40 kPa to save energy.
