H&R Resources Centrix v390.06
Centrix is a centrifugal fan selection program that enables a fan manufacturer to select, design, cost and quote fans for applications. This program does in a couple of minutes what an experienced fan engineer would take many hours to design and cost! Aerodynamic designs and a nominal range of sizes are entered into the program by H&R Resources. These designs are usually provided by the purchaser. H&R Resources can provide fan aerodynamic design criteria if required. The aerodynamic design is what gives a particular fan its volume, pressure and power characteristics. A single aerodynamic design can meet any volume and pressure that you can think of but the size or speed may not be practical due to mechanical limitations (size...
