Dense Phase Software 

NEW FOR 2013! Ask about our new sizing program PNEU DENSE VACUUM  for Vacuum Dense conveying systems.

Our pressure dense phase line sizing program is a powerful tool, but extremely easy to use. This program calculates pressure drops and airflows for any specified line sizes, convey rates, and line routings. Use this tool for estimating your project costs without having to wait for vendor quotes. This can be used by equipment sales engineers for estimating their system costs while they are on the road. You can count on us to receive the support that you need when you purchase this program. Here are some highlights that are included:

  • Tutorial for program use and proper system design.
  • System sizing using up to 3 stepped-pipe sizes.
  • Back-calculate friction coefficients for products from an existing system.
  • Airlock sizing and leakage rate calculations for high pressure airlocks.
  • Pressure pot sizing calculations.
  • Conversion factors for elevations, airflows, metric units, etc.

Dilute Phase Software

Our pressure and vacuum dilute phase line-sizing programs are released. These programs also calculates the airflows and pressure drops for any pipe diameters, convey rates, and line routings. Use this tool for estimating your project costs without having to wait for vendor quotes. This can be used by equipment sales engineers for estimating their system costs while they are on the road. You can count on us to receive the support that you need when you purchase these programs. Here are some highlights that are included:

  • Tutorial for program use and proper system design.
  • System sizing using up to 3 stepped-pipe sizes.
  • Back-calculate product characteristics from an existing system.
  • Airlock sizing and leakage rate calculations for airlocks.
  • Includes pressure drops for clean airline and other miscellaneous components.
  • Can be used for closed-loop or inert-gas systems.
  • Conversion factors for elevations, airflows, metric units, etc.
