The new RDX has much to offerPacked with Performance
The RDX is the ideal dehumidifying wheel dryer to integrate with your central loading system or to handle multiple hoppers. It offers more features as standard equipment with a smaller footprint than comparable systems, giving you maximum performance in minimal space.
Ideal for Bottle Production
The ideal unit when exceptional quality is imperative, the RDX maintains stable IV and low AA levels, and brings moisture content below 50 ppm. It can dry PET in as little as 3 hours.
Touchpad Programming
An easy-to-use touchpad simplifies programming, enabling you to preset operations, monitor settings, view progress and make changes effortlessly.
Energy-Saving Production
Insulated stainless steel construction prevents heat loss while drying resin in half the time, saving hours of energy with every material change.
Virtually Maintenance-Free
Decades of research and development have been poured into our desiccant wheel technology, resulting in a one-of-a-kind desiccant wheel specifically designed for the rigors of the plastics industry. Our desiccant wheel is expected to run up to 15 years, and is backed by an industry leading 10-year warranty. Heater circuits have solid state relays, providing 10 years of maintenance-free operation. Routine maintenance can be performed from the front of the system, quickly and easily.

Drying Blower
Sterling’s desiccant wheel technology is specifically designed for the plastics industry and delivers optimal performance. Its unique, honeycomb design—molecular sieve desiccant, bonded and then baked onto ceramic paper—eliminates powder that can contaminate the system. Its large contact area effectively absorbs at high temperatures, drying resin in half the time while stabilizing dew points at a constant –40°F.
