Eclipse Engineering developed an automated analytical solution for the design of plate and frame heat exchangers

“With the EKLIPS software, we have optimized and engineered designs at proposal”

- Kevin Ceroky, Manager of Research and Development, ITT Standard

Customer need
Reduce material and labor costs associated with their Engineered-to-Order and Standard line of Plate and Frame Heat Exchangers.

The challenge

  • Develop an alternative analytical method to the rules of ASME, Section VIII, Div. 1, UG-34 (Flat heads) that is acceptable to the Authorized Inspector (AI).
  • Reduce head and pressure plate thickness without adversely affecting gasket-sealing performance.
  • The analytical method must be easily repeated by their engineers for all sizes and process requirements.

The solution

  • Eclipse analysts configured the EKLIPS automated finite element system, developed in-house by Eclipse Engineering, such that ITT’s staff can achieve an optimized plate thickness for the head and pressure plates.
  • All plate and bolting stresses are within ASME allowable values.
  • Plate deflections are constrained to a user-provided value to prevent leakage.
  • The finite element solution was confirmed to be conservative with lab testing.
  • Methods, assumptions, and results are completely defined in the analysis report that is also accepted by the AI.

Customer benefits

  • ITT saves hundreds of thousands of dollars annually in material costs.
  • Fully optimized design is achieved in 7 minutes.
  • The head plate is up to 40% (pressure plate is 25%) thinner using the EKLIPS analysis system vs. using the ASME UG-34 method, which makes ITT ultra competitive in the plate and frame marketplace.
