Ranges of validity

Critical data

• Shell and tube heat exchangers (WTS) for single-phase media (gas/liquid), as well as condensation of pure substances
• Pure substance condensers with desuperheating zone, condensation zone and subcooling zone. (KOND)
• Evaporator/ pure substances (VERD)
• Electrically heated forced-flow heaters
• Air coolers/ Tube register heat exchangers with plain or finned tubes (AC)
