These ball expansion machines are very flexible machines studied for the expansion of coils of medium/large dimensions. The tubes (or hairpins) are expanded by means of balls pushed by water or oil at high pressure. The parts of the circuit with water in pressure are in stainless steel. The machine is predisposed for the utilization of evaporative oil.
