We only concentrate on Heat Exchangers

From simple Oil Coolers to complex Shell and Tube Heat Exchangers. Heft can design and manufacture heat exchangers related to almost all industrial application.


Heft, specially developed software carries out calculations related to minor aspects of mechanical and thermal designs of heat exchangers. The software works according to ASME & TEMA STANDARDS.

Size and Types

  • • The sizes range from 2" OD to a few meters, in a single or multiple pass.
  • • Tubes can be straight or 'U' bundle.
  • • Fixed-Tube Sheet Design.
  • • Full-Through Floating-Head Design.
  • • Split-Ring Floating-Head Design.
  • • Bayonet Tube Design.


Heat Exchangers are fabricated in Hastealloy, Inconel, all grade of Stainless Steel & Carbon Steel & any other weldable material operating in moderately high pressure and temperature range.
