Climate-Friendly Cooling Solution With Water as a Refrigerant

The Eco Cooler is a new, sustainable cooling solution for cooling TRUMPF laser machines during the cutting process – using 100 percent water as a refrigerant. The innovation saves 80 percent of the energy previously used to cool the laser cutting machines.

“Sustainability increasingly offers a key competitive advantage – especially given the rise in energy costs,” says Stephan Mayer, Chief Executive Officer for machine tools at TRUMPF. “To ensure their operations remain viable, sheet-metal processors should be shifting to climate- and eco-friendly technologies. The Eco Cooler will help our customers save energy and reduce the use of harmful substances in production. We see an opportunity here to improve the environmental footprint of the industry as a whole and to drive down costs at the same time.”

TRUMPF developed the Eco Cooler together with Efficient Energy. The solution will be unveiled at EuroBLECH in October and will be available for TRUMPF’s 1000 to 5000 Series laser cutting machines thereafter.

“We’re delighted that we could help TRUMPF develop this energy-efficient refrigeration concept with our Blue^zero® technology which uses water as a refrigerant. As a pioneer of this innovative refrigeration technology, it naturally also makes us proud to be supplying our products to an international market leader such as TRUMPF,” adds Georg Dietrich, CEO of Efficient Energy.

Water – The Natural Refrigerant

The clean tech company Efficient Energy uses its Blue^zero® technology in its eChiller product range, enabling water as a climate-neutral refrigerant and dispensing entirely with environmentally harmful F-gases. The technology is ideal for cooling industrial processes, machines, data centres and server rooms in building air conditioning.

The Most Sustainable Chiller Worldwide

Efficient Energy has been producing its entire eChiller product range as climate-neutral chillers since 2022. As such, it has become the only refrigeration industry supplier worldwide to offer climate neutral chillers, and enables its customers to take further decisive steps towards a climate-neutral industry. By combining water as a refrigerant with green electricity, operators achieve entirely climate-neutral refrigeration, letting them reduce their carbon footprints in this area to zero.
