They use the aluminum pipe which many has critisize about its disadvantages over copper pipes. However, I have found a website which shows otherwise. So for those who has installed their aircon using aluminum pipes, please do not worry. From the information I gather, aluminum (alloy) is actually better than copper!http://armourtube.com/eng/articles/why-aluminium-tubes-better.htmlCharacteristic & Advantages over copper][*]Using the same set of tools as flaring copper[*]Higher thickness on pipe enables a more strengthen & even flare[*]Requires lesser strength[*]More flexibility than copper[*]Do not kink easily compared to copper[*]Using the same set of bending tools as copper[*]Brazing[*]No argon gas, wire spool, gloves, shield or electricity required[*]1 Armourbraze rod allows up to 50 joints[*]Fast, easy & secured joints in 10 seconds[*]No turning of torches or rounding up gaps[*]4 times faster than brazing copper.[*]No additional flux required[*]Using the same torch and mapp gas[*]More saving on gas, time and brazing rod due to lower melting[*]point of aluminium[*]Estimated USD 0.05 per joint[*]Joints are stronger than main material[*] [*]Swaging or Expanding[*]30% expansion from original OD[*]Using the same set of swaging tools as copper[*]Longer Length[*]Coils comes in 100m or 50m (bigger size) minimising joints[*]Lesser joints would mean lesser tendency of leakeage[*]Using lesser time, map gas & brazing rod[*]Longer length, lesser wastage[*]Pressure[*]Quatest (Vietnam) tested to meet ASTM B280-02 (9.4Mpa),[*]ASTM E 1251-99, TCVN 1832:2008 (18Mpa)[*]PSB TUV (Singapore) tested to meet ASTM B75 @ 1000PSI[*]Corrosion[*]48 hours salt water test before shipment[*]Corrosion rate is very much lesser than copper[*]Oxidisation rate is also lower making pipes clean and bright when exposed[*]Thermal Conductivity[*]Lower than copper by almost 50% which means lesser rate of condensation[*]Examples of aluminium tube being used[*]Air-conditioning in all automobiles[*]Refrigerator[*]Fan Coils of Air-conditionersLast but most importantly, the aluminum pipe creation air use is strangently tested by PSB.
