MicroGroove Update:
A Brief History of MicroGroove

Small Tube Copper Is Economical and Eco-Friendly

It packs all the advantages of copper into more compact, more efficient heat exchanger coils, reducing the cost of high efficiency air conditioners and refrigerators.

Using proven, cost effective copper fabrication processes and familiar assembly techniques, suppliers and manufacturers are already producing new commercial and residential air conditioning and refrigeration products based on small diameter MicroGroove copper tubing.
