Finally, an all-aluminum high performance dryer that reduces energy costs by upwards of 75% and outlasts the competition. From concept to completion, our dryers are engineered to work with Dryer IQ (featuring variable frequency drive technology). While other dryer systems reduce energy consumption with the use of dampers, AutoVac goes one step further. Dryer IQ electronically reduces RPMs to cut energy costs exponentially. Our intelligent dryer system features engineered castings that maximize airflow for unbeatable performance. The all-aluminum construction stands up to the harshest tunnels without corroding, cracking or fading. Superior design and durability. Competitive cost. Unbelievable energy savings.
