Facilities & Equipment


Golden, Colorado, has been home to Hazen since it was founded in 1961. Each of the 18 buildings has specialized equipment that provides flexibility for evaluating different unit and plant operations. Our facilities are equipped to handle hazardous and corrosive materials, radionuclides, and high pressure and high temperature reactions. We have a NEMA Class I Division 2 manufacturing space for large quantities of flammable and combustible materials.

Fabrication Facilities

Hazen also operates a fabrication and machine shop where equipment is designed, configured, repaired, calibrated, or manufactured according to project needs. We maintain an in-house instrumentation and controls department that is integral in designing, installing, and configuring process controls for our project work.


Hazen maintains an extensive collection of process equipment for laboratory- and demonstration-scale programs. Our inventory allows us to provide a number of services that cater to the exact needs of our customers. We use state-of-the-art equipment and instruments and remain up to date in a world of rapid growth and change. In addition to our current inventory, Hazen has the capability to make onsite additions that are necessary thanks to our internal fabrication shop.
