JAZO Cuts Design Time for Outdoor Transformer Housings from 3 Weeks to 1 Day Using Pro/ENGINEER and FloEFD.Pro

FloEFD.Pro analysis results depict amount of pressure loss on a JAZO housing

March 2007

JAZO Zevenaar B.V. used a combination of PTC Pro/ENGINEER from PTC and FloEFD.Pro from Flomerics to cut 20 days from their design cycle for four new weatherproof, outdoor transformer housings.

"The combination of Pro/ENGINEER for solid modeling and FloEFD.Pro for airflow analysis allows us to test our louvers for form, fit and function effortlessly" said Henry Aaldering, technical director at JAZO. "We can show the finished design to our customer complete with how it will look and work in just one day – that's a saving of 3 weeks and thousands of Euros for each model. In Holland, physical prototypes may be tested at special organizations but this is slow and rather expensive and a one day session at these organizations costs around €2,500."

JAZO is widely known for its expertise in designing, manufacturing and marketing protective housings for electricity, gas, telecommunications and boilers. The louvers which are manufactured from aluminum and steel are thin yet quite resilient. These patented structures are flexible and can be customized to fit any height – JAZO has about 50 profiles to match all customer requirements.

While creating their new family of transformer rooms, the team found that minimizing pressure loss was a major design challenge. The rain resistant structures rely on natural ventilation; therefore, pressure loss results in less airflow through the housing and hence higher temperatures. With an extensive range of new designs, creating physical prototypes for each design permutation was not financially feasible. By standardizing on Pro/ENGINEER and FloEFD.Pro, the JAZO engineering team was able to create and test multiple prototypes quickly.

In addition, the group fed the results from FloEFD.Pro into Pro/MECHANICA as input for structural analysis. "Using an integrated design, FEA and CFD process has definitely helped us save time and money and given us a competitive edge" said Aaldering. And it seems their customers agree as JAZO is the leading company in Holland for safety ventilation louvers and facades for utility buildings which have to be ventilated.
