Coils are made of heavy duty pre galvanized precision tubes To increase the surface area we use aluminium plate fins.The aluminium fins have got nearly five times better thermal conductivity as against steel fins.Aluminium fins ensures rapid heat absorption from the air.The tubes are expanded by mechanical expansion to have excellent bonding between the fins and tubes.
