Edwards supplied a two-module dry pump steel degassing system to Tenova Core as part of a secondary metallurgical facility for McConway and Torley (M&T), a steel foundry in eastern Pennsylvania. The system forms part of a ladle refining and vacuum degassing station that Tenova Core installed at M&T. The Edwards dry pump system provides M&T with potential energy cost savings of more than 90% over traditional steam ejector systems. Other benefits include a lower environmental impact through reducing water effluent and CO2 emissions, optimized steel quality by eliminating moisture contamination, consistent vacuum quality and increased safety through removing the need for high-pressure steam and high-temperature fuel burner systems.

Each of the Edwards’ steel degassing modules comprises an HV30000 high-capacity vacuum booster pump backed by a SN7000 high-compression booster pump and one of the latest generation IDX1000 dry screw pumps. The pumps are manufactured in Shoreham, U.K. and in Lutin, Czech Republic. The system was assembled in the U.S. prior to installation and commissioning, which occurred in the second quarter. M&T supplies coupling sets for railway freight wagons to the U.S. and Canada.
