  1. Johnny Mook from * Interior Design did an amazing job with our resale Flat at Tampines. He turned an old flat with very out-dated design into a modern resort-style design. My wife and I were truly amazed at how creative Johnny was by delivering to us our dream resort-style home. Now everyday when we return home from work, its like we are going back to a resort home, very relaxing. Thank you so much Johnny Mook, for making our dream home come true! Highly Recommended! Please contact him at 81577430.
  2. Please refer to below for the changing trend for air con installation. Aluminum alloy is now a better material because the grades are better now and fully tested by PSB! Characteristic & Advantages over copper Flaring Requires lesser strength Using the same set of tools as flaring copper Higher thickness on pipe enables a more strengthen & even flare Bending 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-conditioners
  3. Hi Everyone I just installed the York system 3 inverter system by Creation Air. 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.html Characteristic & 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.

  4. Wow looks impressive. My house is being done up by Johnny as well. Hope everything turns up as nice as your place.
