CorruFin/ET (Pat. Pending)
Energy Transfer • MDE's CorruFin/ET finned tubing offers two enhancements to thin walled bare tubing. The corrugation on the inside diameter of the tube assists in heat transfer by creating a spiral groove. The fins are embedded into the groove causing excellent tube to fin engagement. CorruFin/ET is available with or without brazed fin to tube bond.
