Large Environmental Test Chamber

Product feature
● The high performance scroll compressor is used to adjust the refrigeration output, save energy, save electricity, and keep a constant temperature.
● Special liquid is injected into the cooling compressor cavity, and the cavity can be precisely controlled. Even if the ambient temperature is very high, it can still function normally, with high reliability and stable performance.
● Through advanced technology and humanized design, the perfect series is making continuous progress for lower environmental pollution and lower energy consumption.
● The continuous and stable reliability and competitive price make this series of products have a broad market area.

Product Application
● This equipment is suitable for various electrical and electronic products and other products, parts and materials to carry out environmental simulation reliability tests such as high and low temperature constant and gradual changes, and damp heat tests.
● Any use other than this may result in personal injury and damage to equipment.
