Performance advantages

1. Fully Compliant with LV124 K-12 Splash Water Temperature Shock Test: the test chamber is designed strictly according to LV124 Section 9.12, with all key parameters accurately controlled. The splash water temperature is maintained between 0 °C and +4 °C, with a 3-second splash duration and a controlled water volume of 3–4 liters per splash. The distance between the splash nozzle and the DUT is set at 300–350 mm, and the test runs in 30-minute cycles for up to 100 cycles. By keeping all these conditions stable and repeatable, the chamber delivers reliable test results that meet the validation expectations of automotive OEMs and Tier-1 suppliers.

2. Integrated Low-Temperature Splash Water Control with Water Circulation and Filtration: unlike standard temperature chambers that rely on external water supply, this chamber features an integrated cold splash water system. The built-in water tank keeps the splash water consistently at 0–4 °C throughout long test programs. A closed-loop water circulation and filtration system, combined with copper piping and a high-efficiency mechanical refrigeration unit, ensures stable cooling performance and reliable operation during continuous LV124 K-12 testing.

3. Realistic Temperature Shock Simulation with +150 °C Heating and 0–4 °C Cold Water Splash: the chamber supports heating the DUT from ambient temperature up to +150 °C before splash exposure. When cold water at 0–4 °C is applied for 3 seconds, the surface of the component experiences an immediate temperature drop. This rapid change creates a true thermal shock effect, helping to identify sealing weaknesses, material stress, and potential functional issues that cannot be detected by slow cooling or standard temperature cycling tests.

4. Centrifugal Fan Air Circulation for Stable Sample Temperature: A centrifugal air circulation fan ensures steady airflow inside the 1000-liter test chamber during heating and between splash cycles. The optimized airflow design helps maintain stable and even temperature conditions around the testing sample, reducing temperature fluctuations and improving test repeatability. This stable temperature cycling performance is especially important when testing multiple samples at the same time or running long-duration LV124 K-12 test programs.

5. Robust Construction for Wet Testing:the chamber interior is constructed from SUS304 stainless steel, offering excellent corrosion resistance under repeated water exposure and high-humidity conditions. Separation of water and electrical systems, combined with multiple safety protections, ensures long-term operational safety and durability.

6. Intelligent Control and Data Management: a programmable color touch-screen controller supports multi-step test programs, intermittent DUT operation, and precise timing of splash events. Continuous parameter monitoring and data storage allow engineers to verify component performance before, during, and after testing, fully supporting LV124 functional verification requirements.
