Design

In Precision we are strongly committed to support our Customers since the very early phase of the projects. Our design engineers are deeply involved in the thermal design of heat exchanging equipment. Thanks to our process knowledge and our acquaintance with process simulation, we are able to address the technological choice for each process and custom-design each single equipment, supporting our Customers in defining the most efficient and cost-effective configuration. Our Thermal team supports all the technologies in our portfolio.

Products

Our heat transfer specialists design and rate:

  • Any conventional TEMA type Shell & Tube Heat Exchangers
  • High pressure Heat Exchangers
  • Hair-Pin type Heat Exchangers
  • Pressure Vessels & Reactors

Additionally, we have experience in manufacturing Helical Baffle Heat Exchangers & Rod Baffle Heat Exchangers.

Softwares

In Precision, we use widely recognized software:

Thermal Calculations

  • Xchanger Suite package powered by HTRI
  • Aspen Shell and Tube Exchanger

CFD Analysis:

  • ANSYS

Finite Element Analysis

We have in-house capability for Mechanical design & preparation of detailed fabrication drawings. Over a period of 40 years, the company has also developed many in-house tools for designing certain aspects which are not covered in commercially available software. The output is a clear and detailed fabrication drawings which captures all the customer requirements including their specific quality requirements.

The design department also works closely with all the other departments so that if there is any post order changes the same gets captured and communicated through the system without any loss of information.
