At its in-house exhibition INTECH, high-tech company TRUMPF is showcasing a new cooler for its laser cutting machines. The new unit is capable of reducing energy consumed during the cooling process and uses fifty percent less energy than conventional solutions. Unlike conventional coolers, the main components of this new solution— such as pumps, fans and compressors— are equipped with a rotational speed controller. This enables the solution to use only the amount of energy actually required to cool the laser.

This allows for a great deal of energy to be saved, particularly when cutting thin sheet metal or during planned breaks in processing. ‘With the energy-efficient cooling unit, TRUMPF is continuing to make sustainability advancements in industrial production. Users not only save electricity and CO2— they also reduce energy costs in the process. This helps companies to remain competitive,' says Fabian Staib, product manager at TRUMPF. Due to its high energy savings, the energy-efficient cooling unit pays for itself in less than four years. With a surface area of just one square meter, the cooler easily fits into any production environment. TRUMPF currently offers the solution for its laser cutting machines with 24 kW laser power. In the future, the high-tech company also intends to launch the cooling unit for other laser power levels.

With the new cooling unit, TRUMPF is helping sheet metal processing companies reduce their consumption of coolants in line with the Kigali Amendment, a 2016 agreement stipulating the global phase-out of environmentally harmful refrigerants. The cooler’s refrigerant, R513a, has a significantly lower global warming potential and thus meets the Kigali Amendment’s stricter regulations.
