The Modular Combined Rotary Dehumidifier (Model: PRI-1) is a game-changing humidity control solution developed with patented technology. As a leading Rotary Desiccant Dehumidifier, it is specifically engineered for existing workshops needing additional humidity control—no foundation or ductwork required. Lightweight and easy to move, it can be installed and used immediately, making it a cost-effective choice for technical upgrades. Its core component is a Desiccant Rotor that rotates continuously (8~16 hours), divided into a 270° treatment zone and 90° regeneration zone. Moist air passes through the treatment zone, where moisture is adsorbed by the desiccant rotor, producing dry air. The rotor is regenerated via a PTC Heater, ensuring consistent dehumidification performance.
Breaking away from traditional rotary dehumidifier structures, this Portable Modular Dehumidifier features an innovative design that eliminates the need for complex installation. Each unit is self-contained, requiring no foundation or ductwork, and can be operational within hours of unboxing. It is optimized for drying rooms with a height of 2.6 meters and area of ~25 square meters, controlling temperature and humidity within 25℃ and 20% RH—meeting most production process requirements.
One of the standout benefits of this Modular Dehumidifier is its flexible combination capability. When drying room area increases, multiple units can be used together to expand dehumidification capacity. For spaces needing ultra-low humidity, adding more units reduces humidity to as low as 10% RH (at 25℃). This scalability makes it ideal for environments with changing or strict Low-humidity Process Requirements, such as electronics manufacturing or pharmaceutical drying.
With a rated power of 6.67 kW and actual operating power of 4 kW after stabilization, this Low-energy Dehumidifier uses half the energy of similar units. The efficient PTC Heater for rotor regeneration and optimized fan systems minimize energy waste, reducing long-term operational costs. For businesses focused on sustainability and cost control, this energy-efficient design is a key advantage.
Measuring just 803×667×1650 mm and weighing 200 kg, each unit occupies only 0.5 square meters—making it a Compact Dehumidifier that won’t disrupt existing workshop layouts. Its small footprint is perfect for crowded production areas or spaces where floor space is at a premium, ensuring easy integration without compromising workflow.
Unlike traditional dehumidifiers that require extensive ductwork, this model operates without it—saving significant engineering and supporting work. This not only reduces installation time and costs but also allows for flexible repositioning if production layouts change. It’s the ideal solution for retrofitting existing facilities with minimal disruption.
The rotor regeneration system uses a new PTC Heater that is highly efficient, safe, and long-lasting. Unlike traditional heaters, PTC heaters offer stable temperature control, reducing fire risks and extending component lifespan. This ensures reliable regeneration, maintaining the desiccant rotor’s adsorption capacity for consistent dehumidification.
For workshops already in operation, this Modular Combined Rotary Dehumidifier enables easy humidity control upgrades without downtime. It requires no modifications to existing structures or ductwork, allowing businesses to enhance production quality quickly. Whether you’re adding humidity control to a electronics assembly line or a food processing room, it integrates seamlessly.
Ideal for industries requiring strict low-humidity conditions—such as lithium battery production, optical component manufacturing, and pharmaceutical drying—this dehumidifier delivers High-precision Humidity Control (15%~24% RH as standard, down to 10% RH with multiple units). It ensures consistent product quality by eliminating moisture-related defects like condensation or material degradation.
For drying rooms of 25~100 square meters, this dehumidifier offers a cost-effective alternative to large, fixed systems. Its modular design allows businesses to start with one unit and scale as needed, avoiding over-investment in oversized equipment. The low energy consumption and minimal maintenance further reduce total cost of ownership.
