Boston Class Almost Sold Out
Our first Fall FLO-MASTER class will be held September 14-15 in Boston, MA and we only have 3 seats remaining! If you are interested in going to the Boston class please call today. Our last two classes of the year will be held in Chicago and Las Vegas and both of those classes have been selling quickly as well. Sign up now while space is still available.
The seminars are two days, with the second day completely focused on real-world examples and hands-on use of the program. Examples will include advanced pump selection, variable frequency drive analysis, advanced controls, balancing a system, system expansion and building a system from scratch.

2006 FLO-MASTER Schedule:

  • Boston, MA – September 14-15

  • Chicago, IL – October 12-13

  • Las Vegas, NV – November 9-10
To find out more about the upcoming FLO-MASTER Seminars visit http://www.eng-software.com/products/flomaster.aspx or call (800) 786-8545. The seminars qualify for 15 Professional Development Hours needed to fulfill Professional Engineers’ continuing education requirements in many states.
Pump Training Courses Offered by Noted Consultant and Author, Michael Volk.
Classes for engineers, maintenance technicians, and pump sales and applications personnel will be held in:
  • September 6-8, 2006    Long Beach, CA

PIPE-FLO Feature of the Month
Modeling a Variable Speed Pump in PIPE-FLO

When designing systems in which the system demand varies (for example, HVAC systems with varying loads throughout the day or year), variable speed pumps may be an effective cost savings option.  In these systems, the pump speed can be adjusted to meet the varying demands of the system.
In this example, there are two different operating points:  The design point which the pump was originally sized for is at 600 gpm.  There is also a secondary operating point which is at 400 gpm.  When the system is required to operate at 400 gpm, there are two options:
  1. Run the pump at a fixed speed and introduce more resistance into the system (for example, by using a control valve).  The dP shown in Figure 1 (click below) is the pressure drop required across the valve to limit the flow rate to 400 gpm.  The energy dissipated by the valve is wasted energy.
  2. Use a variable frequency drive to adjust the pump curve down to meet the 400 gpm operating point (click below).  This option saves energy, but the savings in operating cost must be weighed against the cost of implementing a variable speed drive.

New ESI Corporate HQ Almost Complete!
Move to Happen in Late August
Engineered Software is pleased to announce that we will be moving into our NEW corporate headquarters at the end of August! We are bursting at the seams here at 4531 Intelco Loop, so we are moving all the way across the parking lot to 4529 Intelco Loop! We have been joyously watching the construction of the building since it began in August of last year, eagerly anticipating the added space and comfort of a brand new building.
The good news to you is that the move will allow us to better serve our customers and will provide us room to continue to grow and build engineering programs that exceed the expectation of our users. There will be other advantages such as a new phone system which will allow for better communication with customers and we will be able to reclaim our conference room (which we had to turn into offices since we ran out of room!). We couldn’t be more excited about the move and we will make certain to share pictures of the new building soon.

ESI Around the Globe
Early in September ESI travel will kick back into full swing. Our Chief Engineer, Ray Hardee, will be in New York City and Philadelphia, PA the first week of September visiting customers and prospects. We are also planning a trip to Houston in early September. Finally, don’t forget about our first Fall FLO-MASTER class in Boston on September 14-15.
If you are in NYC, Philadelphia, Houston or the surrounding areas and would like to learn more about PIPE-FLO, please call us at (800) 786-8545 or email us at sales@eng-software.com.
