  • Economical, Eco-friendly Copper Tubes for Air Conditioner Applications - Smaller, grooved tubes make possible smaller, more efficient heat exchanger coils... and hence air conditioners with high energy-efficiency. Coils made with this new technology weigh less and take up less space. They use less refrigerant and operate at higher pressures. The cost effective copper fabrication processes and assembly techniques are proven and familiar to suppliers and manufacturers. Corrosion resistant, durable and dependable, copper tubes provide long life, reliable performance and recyclability. New commercial and residential air-conditioner products based on small diameter copper tubing are already changing the game.
