Cooling is done by means of Air Coolers. The compressed air is cooled with the help of outside air. To increase the surface, fins have been applied to the tubes.
A Dutch manufacturer of compressors supplies an air compressor in Indonesia.
Because the pressure is relatively low and it is a widely used application, the end customer expects a compact standard solution, but there are customer-specific wishes. Because the process is clean, the tubes do not have to be accessible. Together with the design pressure and temperature, this offers the space to use a compact, integrally welded bonnet construction. In addition to being compact, this construction is also cost-efficient.
It concerns two Air Coolers with single-pass high finned (aluminum fins) bundle with integrally welded bonnet type headers, type BHFB 4/4400 × 1330 entirely in C-steel according to PED cat. II / Mod A2 and ASME VIII Div. 1
