Trumpf uses pure water as a coolant in its laser cutting machines


International. Trumpf, a manufacturer of industrial machines, developed a sustainable cooling solution for laser cutting machines. Conventional refrigeration systems use fluorinated gases, also known as F gases, as a refrigerant. In contrast, the brand's Eco Cooler uses pure water as a coolant.

As a result, it uses up to 80 percent less energy for cooling and completely dispenses with harmful substances. The company ensures that the solution is unique in the sheet metal industry.

"Sustainability increasingly offers a key competitive advantage, especially given rising energy costs," says Stephan Mayer, CEO of Trumpf. "To ensure their operations remain viable, sheet metal processors should switch to climate- and environmentally 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 reduce costs at the same time."

The Eco Cooler was developed by Trumpf in collaboration with Efficient Energy. Following the EuroBLECH trade fair, this new solution will be available for Trumpf laser cutting machines from the 1000 to 5000 series.

First use of water as a coolant
Trumpf and Efficient Energy managed to develop a water-based cooling solution as a mass production system for use in sheet metal processing. The Eco Cooler takes advantage of the excellent cooling properties of water and works as follows: water flows into heat-generating components such as laser diodes, optics, drives and control cabinets. Once these components are cooled, the water returns to the Eco Cooler, where it is cooled by a heat exchanger in an innovative process involving evaporation, compression and condensation. "The Eco Cooler works like a heat pump," explains Andreas Hultsch, Trumpf's project manager. "It allows users to control the temperature of components that generate heat during laser processing and also regulate volume flow rates."

Lower costs, better environmental protection
With Eco Cooler, on average, carbon emissions are reduced by 15 metric tons per year, which equates to savings of around €10,000. F-gas dispensing eliminates refrigerant costs and reduces another 12 metric tons of carbon. The solution is ideal for all sheet metal processors who want to make their operations more sustainable and also more economical, from newcomers to industry to smart factory operators. In many countries around the world, state funds are available for companies looking to make this transition. Depending on the machine's capacity utilization and the level of government support, the Eco Cooler can be amortized in three years.

Sesión 5: Desinfección en ambientes críticos bajo recomendaciones de ASHRAE

Esta charla estará enfocada en las recomendaciones de ASHARAE para la desinfección de ambientes críticos como lo son quirófanos o salas de hospitales, garantizando una ventilación adecuada para reducir el riesgo de infección. Nos enfocaremos en los productos que Carrier ha lanzado al mercado para cubrir esta necesidad inmediata. Ing.William Sanchez - Grupo Clima

Sesión 4: Minimizando las Infecciones Asociadas a la Atención de la Salud (IAAS)

Como se pueden minimizar las Infecciones Asociadas a la Atención de la Salud (IAAS) al proveer el flujo de aire y la presurización adecuada en los ambientes críticos. Roberto Rouanet, Business Developer Building Products - Siemens Colombia

Sesión 3: Hospitales: Salas de Presión Positiva y Negativa

Los centros hospitalarios tienen requerimientos de salas o zonas de presión positiva y negativa con el objetivo de proteger a sus pacientes, trabajadores y usuarios de las áreas de infecciosos (salas de presión negativa) o inmunodeprimidos (salas de presión positiva). Estos espacios aislados por diferencias de presión se consiguen a través de los sistemas de control de los equipos de climatización de las instalaciones. Estas salas de presión Negativa o Positiva son una parte imprescindible en centros médicos y de investigación, ya que ayudan a mantener las condiciones sanitarias necesarias para un ambiente limpio. Jose Jesús Arboledas Herranz, Responsable de proyectos especiales - KEYTER
