Axial Flow Pit Turbines

Improved Technology and Design

CHC has provided pit-type axial flow turbines to several projects over the years, and improved the design with each installation.  Thanks to its research and development team, CHC has perfected this equipment configuration in order to improve not only its operation and performance, but also to increase profitability for project owners.  Now working with its third generation design of pit turbines, CHC manufactures direct-connect horizontal units in sizes ranging from 1250 mm to over 3200 mm.
