In an era defined by technological advancement and green manufacturing, environmental testing technology is stepping into a new dimension. DHT® proudly unveils its latest innovation: a CO₂ environmental simulation chamber that redefines precision in gas control and achieves a leap forward in energy efficiency, operational safety, and system integration.
This isn’t just a new piece of equipment — it’s a strategic upgrade rooted in system-level thinking, purpose-built to meet the evolving demands of high-end laboratory and industrial testing scenarios.
Breaking Barriers: Solving Long-Standing Challenges in CO₂ Testing
Traditional CO₂ environmental chambers often struggle to keep up with increasingly complex testing requirements. Have you encountered these issues before?
-
Unstable CO₂ concentration, leading to poor data repeatability;
-
High operational costs and excessive gas consumption;
-
Lack of integration with larger testing systems (such as drive-in chambers), resulting in isolated, inefficient setups.
-
Lack of real-time remote data monitoring hinders post-test analysis and quality traceability.
The new DHT® CO₂ simulation chamber addresses these challenges at the architectural and algorithmic levels, delivering unmatched control precision and seamless compatibility for scientific and industrial environments.
Core Innovations: More Than an Upgrade — A Complete Reinvention
Precision Control: Closed-Loop CO₂ Regulation with < ±0.1% Deviation
Equipped with high-sensitivity infrared sensors and advanced dynamic PID algorithms, the system ensures stable and responsive gas concentration adjustments. Whether during frequent door operations, extended test cycles, or sudden environmental fluctuations, the chamber maintains optimal CO₂ levels to ensure data integrity and experimental reliability.
Energy Efficiency: AI-Optimized Control Reduces Costs by Over 35%
The system leverages intelligent algorithms, optimized gas pathways, and integrated modules to dynamically regulate CO₂ flow based on demand. This not only minimizes energy consumption but also extends the service life of consumables — making it ideal for labs and facilities focused on ROI and long-term cost savings.
Modular Integration: Seamless Compatibility with Drive-In Chambers
Designed for high system compatibility, the chamber includes modular hardware and communication interfaces that support multi-parameter coordination with large-scale environmental systems (temperature, humidity, airflow, etc.). It functions equally well for standalone testing or as a core node within full-vehicle, battery, or server-level test environments.
One Device, Multiple Applications
This CO₂ chamber is versatile enough to serve both standalone functions and complex integrated testing ecosystems. It is widely applicable to:
-
Life Science Laboratories – Maintaining precise CO₂ levels for optimal cell culture conditions;
-
Pharmaceutical & Biotech Manufacturing – Supporting GMP-compliant batch consistency testing;
-
Carbon Neutrality Research – Simulating carbon environments for materials testing;
-
New Energy Vehicle (NEV) Testing – Used with drive-in chambers for battery durability testing in high CO₂, high-temp, and high-humidity environments;
-
Server & Electronics Testing – Assessing ventilation and heat dissipation in high-gas-density enclosed spaces.
Real-World Success Stories: Tangible Efficiency, Measurable Value
Case 1 | Life Sciences: Elevated Precision, Improved Throughput A leading vaccine research facility struggled with unstable CO₂ levels, leading to low cell viability and high experiment failure rates. After switching to DHT®’s new chamber, CO₂ fluctuations were reduced to within ±0.1%, resulting in a 30% increase in successful cell cultures and significantly shorter test cycles.
Case 2 | EV Industry: Integrated Modules for Full-Stack Validation A global automaker integrated the new DHT® chamber into its existing drive-in testing setup, creating a high-temperature + high-humidity + high CO₂ + vibration multi-condition environment. This significantly improved defect detection rates (3x increase) and reduced the product development cycle by approximately 20%.
