New Vortech(tm) Pulper Rotor Introduced By Kadant Black Clawson

Substantial Power Savings Achievable with New Design

Mason, Ohio, USA: Kadant Black Clawson Inc., a subsidiary of Kadant Inc., introduces the new Vortech(tm) pulper rotor. The Vortech is the latest generation of Kadant Black Clawson performance rotors, capable of achieving up to a 30 percent savings in operating power.

The new pulper rotor incorporates some of the key design features of the company's most popular and industry-proven Vokes(tm) rotor. These features have been coupled with design innovations based on advanced Computational Fluid Dynamics (CFD) and rigorous testing to develop the Vortech. The highly efficient Vortech offers significant power savings while maintaining excellent circulation and defibering properties.

"Energy costs have always been a key factor in any mill operation," states Woody Tyler, Vice President of Sales. "The development of the Vortech provides our customers with an immediate way to reduce their energy costs substantially without sacrificing performance. In fact, we like to say that the Vortech is 'bolt-in power savings.'"

The Vortech has been tested on a variety of furnishes, from virgin market pulp to wet strength linerboard, demonstrating excellent performance in each application. Current field data mirrors the same favorable results. The new Vortech can be retrofitted to any pulper application and no speed change is required.
