This equipment is a large walk-in composite salt spray test chamber, primarily used for accelerated corrosion testing of complete vehicles or large-scale samples. Its key advantage lies in combining salt spray corrosion testing with various environmental simulations such as drying, humidity, and hot air drying. Through innovative structural design, including a monolithic corrosion-resistant chamber and flexible spray/exhaust systems, it enables rapid and stable combined environmental testing cycles within an ultra-large workspace.
