Super Radiator Coils, Chaska, Minn., is offering new designs of coil products made from smaller-diameter copper tubes. Products made with MicroGroove technology include condenser coils, evaporator coils and air handlers.

According to the company, copper coils using MicroGroove offer features unavailable using other materials technologies such as conventional-size round tubes or brazed-aluminum flat tubes. The technology can be applied to manufacture coils with tube lengths up 8' in length.

When the smaller-diameter copper tubes are used to construct large-area heat exchanger coils, energy savings, materials savings, reduced refrigerant charge and smaller footprints can be achieved, according to the company.
