Principle of LDS

LDS, a twin desiccant wheel system, was first introduced to the lithium battery industry in 2008. Today, it has become a standard solution for industrial applications requiring precise control of extremely low dew points.

The system enhances energy efficiency through optimized reactivation heating and reduced cooling requirements, particularly when treating makeup air at unreasonable low temperature.

1. The LDS is an integrated desiccant dehumidification system featuring multi-functional components, including air filters, pre-cooling/heating, mid-cooling, and post-cooling/heating stages.

2. The LDS, equipped with twin desiccant wheels, separately treats makeup air and return air. Combined with energy recovery technology, the system achieves a dew point as low as -80°C while maintaining energy-efficient operation.

3. The system adopts a modular design for easy transportation and on-site installation. Its airtightness is ensured by patented sealing technology, complying with industry leakage standards.

4. The insulation panel is 50mm thick and constructed in a sandwich-type configuration, meeting the EN 1886 TB2 standard for thermal performance.

5. The multi-seal casing design ensures minimal air leakage, achieving EN 1886 L1 certification for casing integrity.

6. The reinforced internal frame structure guarantees casing strength, complying with the EN 1886 D1 mechanical stability standard.

7. The patented pneumatic slide filters ensure easy maintenance and airtightness, with bypass leakage rates meeting the EN 1886 F9 filtration efficiency standard.

8. The factory-installed electrical enclosure (E-box) is rated IP54 for dust and water resistance.

9. The AI-enhanced control software optimizes energy consumption across cooling, heating and gas supply systems, achieving significant operational savings.

10. The LDS system complies with international certifications, including UL (Underwriters Laboratories) and EC (European Commission) directives.
