Program description



Cross-flow heat exchangers / air coolers

Standard version of register heat exchanger with plain or different finned tubes, partial condensation with additional physical properties (see scope of delivery)



Cross-flow heat exchangers / air coolers

Calculation of intermediate temperatures and steam / condensate quantities in steam / post-steam condensation in heat exchanger groups (12 heat exchanger arrangements)


Multi-component condenser

Cross-flow condenser with smooth / finned tubes incl. DDB-Flash. (Multi-component condensation in the tubes)



Shell and tube heat exchangers

Basic version for the calculation of single-phase media (liquid / gaseous), condensation of pure substances on smooth pipes, strongly revised tube sheet layout module SPIE, true-to-scale sketch
(see scope of delivery)

Additional modules for WTS

2. Double-pipe heat exchanger(concentric annular gap) and hairpin heat exchanger (hairpin, shell without baffles). Thermal and hydraulic design of a hairpin heat exchanger incl. modules G2 + GGO + GGLR


3. Fin block Thermal and hydraulic calculation of shell-and-tube heat exchangers with fin block



Electric heater

Standard version for thermal and hydraulic design of forced-flow, electrically heated shell-and-tube heat exchangers


Extra charge to WTS
(requires latest version)



Evaporation of pure substances on smooth pipes incl. tube sheet library, TEMA, with additional physical properties
(see scope of delivery)


Helical coil heat exchangers
