1 Replacement Condensers Charge Level Adjustment May be Necessary

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

3 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 3 Flat Micro-Tube Flat Macro-Tube

4 4 16 x 1 mm, 15 Passages,.4 x.8 mm 16 x 1.75 mm, 16 Passages,.7 x 1 mm 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 Actual Size!

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

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

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

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

9 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 9 Piccolo Condenser Held 47 oz. Pp

10 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 10 Pp

11 Perform Temperature Test to Validate Charge Level Start at 80% of Original Charge Add 1-2 oz. Increments Monitor the Three Dees Condenser Drop 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 11 Pp
