BHDT is also a contractor for large industrial plants, particularly in the field of Low Density Polyethylene (LDPE) and is a partner for specialized equipment for the chemical industry.

The high pressure reactor is a very essential part of an LDPE plant. The ethylene gas is pressurised in a two stage compressor and transferred via preheater to the high pressure reactor. The polimerisation process from ethylene gas to LDPE takes place in the high pressure reactor and is cooled down in the following product cooler.
