The Sukhovey (Mojave Heat) air drying machine is designed for drying of air and removal of solid particles from atmospheric air, as well as for sorbent drying. Dry purified air can be used for purging of transformer tanks and electrical equipment during installation, service or repairs to prevent dielectric insulation from accumulating moisture while the core is exposed.

The vacuum cold trap is designed for evacuation and drying of solid insulation of power transformers with voltages 110-1150 kV during installation, service and repairs.
