About the company

Dzerzhinsky Chemical Equipment Plant “ZARYA” JSC was created in 2005 based on the existing production which was established in 1937. It is a machine-building enterprise specializing in equipment manufacturing for chemical, petrochemical, oil refining and nuclear industries.

The production workshops of the plant are equipped with the necessary process equipment, including procuring, boiler-welding, metal-cutting, machine-tool, forge-and-pressing equipment, enabling performance of a full work cycle.
