Mojave Heat: Hot Air Dryer Unit
The Mojave Heat hot air dryer 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 unit is designed as a metal body separated into two compartments. The unit operates as two independent adsorbers, filled with synthetic zeolite, and a dust filter to remove solid contaminants from the air.
