Copper Tubes
Copper Tube is one of the Components that is needed in Air Conditioning and Refrigerant System. The Tube is used as a path for the Refrigerant to flow between System Components and to Contain it from escaping to the atmosphere. Sizing, Installation Layout and Fittings must be done Properly to ensure that the System runs efficiently.
During Installation, it is of utmost Importance that Moisture, Dirt and other Contaminants are Prevented from entering the System. These foreign particles will affect the Performance of the System and may even cause damage to some of the Components.
During the production of the Copper Tube, the inside of the Tube has been Cleaned and Dried before being sealed at both ends to ensure that it remains that way. You must check to make sure that the Refrigerant that is going to be used does not react with the Copper. Ammonia refrigerant will react with Copper hence it should not be used Instead.
