CHEMCAD THERM

Heat Exchanger Design Software

CC-THERM makes use of multiple international standards for design and materials so you can streamline the process of sizing a heat exchanger accurately. Available as an add-on or standalone product, the design and rating program covers shell-and-tube, plate-and-frame, air-cooled, and double-pipe exchangers. Rigorous designs are based on physical property and phase equilibria data…..

Ideal for Users who want to design or vet a design by a heat exchanger vendor (single unit at a time), and those who want to rate existing exchangers in new service or perform “what if” calculations.

GENERAL FEATURES:

  • Interactive input, calculations, and review of results.
  • Help screens
