For more than 20 years, Emerald Equipment Systems has grown from its upstate New York base into a major Northeast supplier of material-processing equipment and parts. Its 75-acre Liverpool headquarters includes more than 110,000 square feet devoted to service, parts and custom manufacturing, along with a separate site for demonstrating and testing equipment. The company is particularly built around aftermarket support, with in-house fabrication and factory-trained road technicians serving mining, recycling and environmental customers.
