Advantages
1. Integrated Thermal, Humidity-Freeze, and Damp Heat Testing for PV Modules: The chamber supports full-cycle PV module testing, including thermal cycling (–40 °C to +85 °C), humidity-freeze cycling (85 % RH, –40 °C to +85 °C), and damp heat testing (85 °C/85 % RH). This integrated capability allows engineers to evaluate mechanical, electrical, and encapsulation reliability in a single unit, eliminating the need for multiple test systems.
2. High-Precision Control for Repeatable Results: Equipped with PT-100 Class A temperature sensors and PID controllers, the chamber maintains temperature within ±2 °C and humidity within ±2.5 % RH. Uniform airflow and calibrated sensors ensure that each PV module experiences the same conditions, guaranteeing consistent, traceable, and audit-ready test data for R&D, QA, and certification purposes.
3. Large Capacity and Flexible Sample Handling: The chamber accommodates panels up to 2 m(customized) in size, with adjustable racks supporting more than two modules per run. Customizable holders, cable holes, and vertical mounting options allow secure placement of various PV types.
4. Energy-Efficient, Eco-Friendly Operation: Advanced compressor-based cooling and intelligent humidification systems provide rapid temperature transitions and stable humidity control while reducing energy and water consumption. Automatic condensation recycling and low-water alarms ensure uninterrupted long-term damp heat tests up to 1000 hours, supporting sustainable lab practices.
5. Safe, Durable, and User-Friendly Design: Built with SUS304 stainless steel interiors and powder-coated A3 steel exteriors, the chamber resists corrosion, chemical exposure, and mechanical wear. Safety features include over-temperature/pressure protection, fail-safe power shutdowns, and insulated observation windows. A multilingual touchscreen interface allows intuitive programming of thermal, humidity-freeze, and damp heat cycles for quick setup and monitoring.
