Armaflex Insulation


Other than copper pipe. The thickness of the insulation used is a critical factor in Aircon installation. The biggest problem is Condensation from the copper pipe. The thicker the insulation, the harder it is for condensation problem to occur. There is no actual way to cure condensation. The whole set of piping might have to change.


Water pipe


Your Aircon needs a water pipe to drain off the condensed water. From the evaporator coil all the way to a the floor trap. Normal materials for aircon water pipe is 13mm. Where as the upgraded materials is 16mm. The bigger the water pipe, the less likely it is to get choked.
