SubZero Ultra-Compressed Air Chiller: greatly enhance your production with super-chilled compressed air for blow molding of plastic packaging and other applications requiring extremely low temperatures, such as climatic chambers.

In the plastic industry, compressed air at -35°C (yes, that's 35°C below zero!) accelerates the speed of blowing plastic parts by up to 100%, compared to compressed air at ambient temperature.

The renewal of ultra-chilled air during blowing, along with an increase in parison extrusion, drastically reduces the cooling time / part residence time in the mold, resulting in a notable gain in productivity. Additionally, it improves the quality and uniformity of the part, as its cooling occurs on both the internal (super-chilled air) and external (chilled water in the mold) surfaces.

But how does the SubZero ultra-compressed air chiller ensure super-chilled compressed air with high efficiency? Upon entering the equipment, compressed air is treated according to ISO 8573 quality class [1:1:1], with a dew point lower than -70°C. This procedure prevents any trace of moisture from freezing inside the equipment when compressed air is cooled to -35°C.

Count on Metalplan's four decades of expertise to increase productivity in blow molding of plastic parts or any other application essential to your business.

The SubZero ultra-compressed air chiller is 100% manufactured in Brazil.
