Below is a list of some functions:

• Step by step calculation
• Support S.I Units and English (U.S) Units of mesurement.
• User database functions to allow user to add/delete components and load to hot/cold side (Empty database!).
• Ability to import properties to Hot/Cold sides from Microsoft Excel.
• Ability to calculate unknown Cold or Hot side temperatures.
• Perform thermal analysis for bare tube double pipe (hairpin) heat exchangers.
• Perform thermal analysis for finned tube double pipe (hairpin) heat exchangers.
• Choose from Counter Current or Co-Current Flow arrangement
• Choose from Series arrangement or Series-Parallel arrangement.
