After welding, casing components undergo surface finishing using advanced grinding technology to ensure:
- Smooth, polished edges
- Enhanced durability and corrosion resistance
Stringent Quality Control Measures
Even with advanced manufacturing technologies, every component undergoes strict quality control checks:
- Our highly qualified engineers conduct random inspections to ensure all components meet exact specifications.
- Only fully compliant parts proceed to final assembly, ensuring consistent product quality and performance.
Durable & Insulated Casing Design
Our desiccant dehumidifier panels are insulated with rock wool to ensure:
- Superior thermal efficiency (thermal conductivity: 0.035 W/(m•K))
- Noise reduction, allowing installation in workspaces
- Protection against freezing, enabling outdoor installation
All panel joints are sealed with polyurethane or silicone for airtight protection.
Rubber sealing with a metal cord reinforces door and panel junctions, preventing air leaks.
Our units feature a rigid frame construction, maintaining structural integrity and ensuring optimal airflow geometry.

Component Technology & Customisation
At Desiccant Technologies Group, we engineer high-performance desiccant dehumidifiers with cutting-edge components and custom solutions. From advanced silica gel rotors to intelligent controls, every element is designed for efficiency, reliability, and adaptability. Whether standard or tailored configurations, our systems ensure precise climate control across industries.
High-Performance Desiccant Rotor Technology
The desiccant rotor is the core component of our dehumidifiers. We use third-generation silica gel rotors, manufactured in Sweden, known for their high silica gel content and superior moisture absorption efficiency. This results in:
- Higher dehumidification capacity at a lower operational cost
- Efficient humidity control even in extreme conditions (up to 100% RH if no drip moisture is present)
- Silica Gel: 82%
- Fiberglass: 16%
- Acrylic Coating: 2%
- Density: ~240 kg/m³
- Water Vapor Adsorption Efficiency: >40%
- Maximum Compression Strength: >200 kPa
- Flammability Index: 0
- Smoke Emission: 0
To prevent air leakage, the rotor is sealed with silicone tape with a PTFE (Teflon) layer, and separate air streams are maintained using PTFE tape.
For smaller dehumidifiers, we use textolite plates, ensuring high strength with low weight, and minimal friction for smooth rotor operation.
Our rotors are powered by German-engineered gear motors, certified to DIN EN ISO 9001:2008 and compliant with ATEX and IECEx standards. Some models also feature UK-made motors that meet all European certifications.
A toothed belt and rotor hooks efficiently transfer torque from the motor to the rotor for seamless operation.
Energy-Efficient Fan Technology
All our fans are German-made, CE-certified, and built for high efficiency and low noise levels.
MDC1000 and larger models feature EC motor-driven fans, offering:
- 30% energy savings compared to traditional AC motors
- Built-in electronic control systems for optimal performance
- Low noise operation
- To eliminate vibrations, all fans are mounted on anti-vibration supports.
- Adjustable Power Consumption: Models MDC1000 and above come with a potentiometer-controlled system for flexible energy management.
Advanced Filtration System for Air Purity
Our desiccant dehumidifiers are equipped with high-efficiency air filters to ensure clean and contaminant-free airflow:
