Ideal for drying hygroscopic materials, its innovative honeycomb technology ensures a 40% energy-saving compared to conventional twin-tower desiccant dryers. These dryers can be installed on or adjacent to your drying hopper.

• Dust Free – suitable for use inside cleanrooms
• Constant and adjustable dew point of -50°C
• More stable dew point than Twin Desiccant
• 5-Year Guarantee
• Energy Monitoring System
• Air Flow Range of 20-2000m³/h

Within the range, the Drywell and Dryplus models eliminate the need for compressed air or cooling water to dry materials. They can reach drying temperatures of up to 180°C.

Their smart mode feature automatically adjusts the drying process according to production needs by supervising the return air temperature. Furthermore, their Material Protection Management (MPM) safeguards the material from potential over-drying and degradation by closely monitoring the loading system and return air temperature.

What is a Rotor Wheel Dryer?

They represent a shift from traditional dehumidifying dryers, which are often reliant on molecular sieves in pellet form, composed of at least 30% clay. These systems are prone to degradation over time, requiring frequent maintenance and eventual replacement.

The Rotor Wheel Dryer is a compact, efficient, and durable alternative. Instead of using clay-based molecular sieves, they utilise a pure molecular sieve applied to a synthetic substrate. This substrate is rolled into a cylinder, forming a honeycomb structure that facilitates uniform and efficient moisture absorption.

How The Rotor Wheel Dryer Works

The operation of a Rotor Wheel Dryer involves three main sections: drying, regeneration, and cooling. The wheel, powered by a step motor, rotates, channelling the humid air from the material hopper through a return air filter. This air is dried in two stages before being returned to the drying hopper via a heating chamber, courtesy of a process blower.

Concurrently, a portion of the rotating wheel undergoes regeneration in a heat chamber with a separate regeneration blower. Lastly, a cooling section cools down part of the wheel before it re-enters the drying process.

This systematic rotation, regeneration, and cooling ensure the efficient operation of the dryer.

The Advantages

The Rotor Wheel Dryer range from Vismec comes with an array of advantages, making it a popular choice amongst various applications.

• It offers superior efficiency, compactness, and requires minimal maintenance, making it cost-effective long term.
• The dryer is installed separately from the drying hopper, providing flexibility in layout and operation.
• It can reach drying temperatures up to 180°C, with a constant/adjustable dew point down to -50°C.
• A visual and acoustic alarm system ensures safe operation.
• Its Smart Mode automatically adapts the drying process to production needs, eliminating energy waste.
• MPM (Material Protection Management) and SLS (Safety Loading System) features ensure optimal material drying and prevent undried material from reaching the production machine.
