Dust Test Chambers DNDC529 Series – 500 L to 4000 L | Dunel Europe
Dust Ingress Test Chambers — Civil & Laboratory Platform
Engineered for IEC Compliance. Designed for Repeatability.
The DNDC529 Titan Series is designed for IP5X and IP6X dust ingress testing in controlled laboratory environments, where airflow stability, concentration control, and repeatability are critical.
The system uses a vortex-based airflow architecture to maintain homogeneous dust suspension without mechanical agitation.

Dimensional Range — Titan Series
| Model | Internal Volume | External Dimensions (approx.) | Recommended Talc Load | Max Floor Load |
|---|---|---|---|---|
| DNDC529/0.5 | 500 L | 1100 x 800 x 1600 mm | 1.0 kg | 20 kg |
| DNDC529/1.0 | 1000 L | 1400 x 1000 x 1800 mm | 2.0 kg | 35 kg |
| DNDC529/2.0 | 2000 L | 1800 x 1200 x 1900 mm | 4.0 kg | 50 kg |
| DNDC529/4 | 4000 L | 2200 x 1500 x 2100 mm | 8.0 kg | 75 kg |
¹ Based on IEC 60529 standard concentration (2 kg/m³)
Occupancy Compliance
IEC 60529
- Max specimen volume ≤ 33%
- Max floor coverage ≤ 33%
ISO 20653
- Max specimen volume ≤ 25%
- Max floor coverage ≤ 50%
Exceeding these limits alters airflow behavior and compromises test validity.
Typical Applications
- Electrical enclosures
- Automotive components
- Consumer electronics
- Industrial equipment
- Certification laboratories (ISO 17025)
