  1. Replacement Condensers Charge Level Adjustment May be Necessary

  2. Replacement Condensers • Most Vehicles Use Flat Macro or Micro Tube, Multi-pass, Condensers • Virtually Impossible to Flush After Compressor Failure • Will Need to be Replaced. Multiple Passages In Header Tanks Multiple Passages In Header Tanks Sub-Cooling Condenser

  3. Replacing the Condenser? • Condenser Technology Has Advanced • Replacement Condenser May be More Efficient (or Less) than the Original Unit • Replacement (Including OE) May not be an Exact Match for the Original Unit • Tube & Fin May be Replaced by Flat Tube Multi-pass Micro Tube Unit • Flat Tube Multi-pass Macro-Tube Might be Replaced with Thinner Micro-Tube Unit. • System Capacity May be Affected Flat Micro-Tube Flat Macro-Tube

  4. Condenser Tube Comparisons 16 x 1 mm, 15 Passages, .4 x .8 mm 16 x 1.75 mm, 16 Passages, .7 x 1 mm Actual Size! 18 x 2 mm, 10 Passages, 1.24 x 1.35 mm 22 x 2 mm, 10 Passages, 1.24 x 1.75 mm 22 x 2 mm, 13 Passages, 1 x 1 mm 22 x 1 mm, 18 Passages, .4 x .9 mm 26 x 2 mm, 10 Passages, 2.15 x 1.26 mm

  5. F150 - Condenser 1 Replacement Condenser 1 - Muti-pass Tube & Fin (Piccolo) Design – Older Technology Pp

  6. F150 - Condenser 2 Replacement Condenser 2 - Very Large Flat Tube, Single Pass, Serpentine Flow – Older Technology Pp

  7. F150 - Condenser 3 Replacement Condenser 3 - Flat Micro-Tube, Multi-pass Flow – New Technology – Very Efficient Pp

  8. Compare 3. Flat Micro-Tube, Multi-pass Flow 2. Very Large Flat Tube, Serpentine Flow 1. Tube & Fin “Piccolo” Pp

  9. Condenser Capacity “Piccolo’ Condenser Held 47 oz. • We Evacuated Each Condenser & Charged it with Liquid Refrigerant • They Held: • 1. Piccolo = 47 oz. (Matches O.E.) • 2. Serpentine = 43 oz. • 3. Micro-Tube = 26 oz. • We Need to Adjust Original Charge Amount Pp

  10. How to Handle? • Compare Original and Replacement Unit Dimensions • Basic Design – Flat (Micro or Macro) Tube, Serpentine or Multi-pass, Tube & Fin? • Compare # of Tubes • Size of Header Tanks • Connection Line Diameter • # of Cooling Fins/Inch • Condenser Thickness Pp

  11. Confirm Charge Level Perform Temperature Test to Validate Charge Level • Start at 80% of Original Charge • Add 1-2 oz. Increments • Monitor the Three “Dees” • Condenser Drop 20-50 Deg F • Ambient to Duct More that 30 Deg. Difference • Final Charge May be More or Less than Original • When Evaporator Inlet/Outlet Difference = 0 Deg. F Charge Level Correct Pp
