The Mojave Heat air drying unit 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 pulling vacuum and drying of solid insulation of power transformers with voltages 110-1150 kV during installation, service and repairs.
Dried and purified air can be used for purging of transformer tanks and electrical apparatus during their assembling, servicing and maintenance, it is done for prevention of electric insulation from water intrusion when the active core is open to outside of environment. Unit operation mode – continuous.
