Perfect for Preheating Non-Hygroscopic Materials

For non-hygroscopic materials (like Polyethylene and Polypropylene), compressed air drying and desiccant drying is not necessary. Using simple heated air can remove the surface moisture from the pellets. Hot Air Dryers are a simple system, consisting of a heater, a blower, a temperature controller, and a filter. This system is typically paired with a drying hopper for effective drying of non-hygroscopic resins. The system can also be used for pre- or post-drying of hygroscopic resins that have been, or will be thoroughly dried by a desiccant dehumidifying dryer.

Using a modular design, the HAD system can be easily configured to work with various plant layouts and drying configurations.

Designed for preheating non-hygroscopic pellets

The HAD was designed to convey continuous heated air for removing surface moisture from pellets that only capture moisture on the pellet surface.

Modular construction

Adapting easily to every plant environment is just one advantage of the modular construction. Additionally, the modular construction allows for designing perfect sizing configurations for your process needs.

Temperatures up to 250°F

Designed to blow the perfect heated air for removing the surface moisture from the pellet without unnecessarily over drying material.

Remove Surface Moisture with Simple Heated Air

Hot Air Dryers for drying resin use exactly the same drying hoppers as dehumidifying desiccant dryers, and rely on a constant flow of heated air through the hopper to predictably remove surface moisture from the pellets. The only difference is that HAD dryers do not recirculate the air that passes through the hopper. The expelled air passes through an exhaust filter sock. Conair also offers an integrated housing package, similar to Conair’s desiccant dryers, utilizing the heater, blower, inlet filter, and control, into a single, floor standing unit with casters for user portability. These integrated units have CFM capabilities from 75 to 250 cfm, providing throughputs from 150 to 400 lbs/hr.

Modular Unit Throughput

Throughputs from 600-5000 lbs per hour. Available in five models to best suit your requirements.

Integrated Frame Unit Throughput

Throughputs from 150-400 lbs per hour. Available in four models for mobility and smaller throughput needs.
