68 PCB007 MAGAZINE I FEBRUARY 2022 platens in the standard presses, and the platens mechanically are connected to the frame itself. In this scenario, we have, let's say, 10 tons of steel that are being indirectly heated up to then transfer this energy to the panels. Our effi- ciency ratio is equal to the times less of a mass that you are heating up, so our package is being heated up directly by the induction, but we are not heating up the big masses of the platens; not the press, not the room itself. We had calcu- lations done and we are in the range of 70 to 80% savings in energy. Matties: Is this a strategy to bring in a unit like this, make an investment, but ultimately lower their cost of lamination? Lazaro: Yes, it is. Matties: What ROI should they expect on this unit? Let's talk averages. Lazaro: It depends, of course, on the throughput and the kind of panels, but the ROI is between four to five years. Matties: What sort of invest- ment does somebody have to look at compared to a tradi- tional press system? Lazaro: Depending on the options and the size, this machine is in the range of $250,000 or $300,000. A simi- lar system that occupies even more footprint, and needs the boiler for heating the oil, is in the range of $400,000. Matties: So, they save on the money up front, of course. ey don't need a cooling press now also, correct? Lazaro: Correct, because of the installation power. A company needs to have the line big enough to supply the power to the machine. Now this machine has one-third of the installed power.
