    Cooler chiller not climate killer

    The focal point at the Rittal GmbH stand at EMO Hannover 2017 is the company's new cooling solutions for machine tools. Not only are they geared up for Industry 4.0 applications, but they save a whole lot of energy into the bargain, too.

    It is not just machine tools that are being asked to satisfy increasingly complex new requirements, but their peripherals, too. You could be forgiven for thinking that all a machine tool cooling system has to do is cool machine tools efficiently and enable precise temperature regulation. However, as with almost everything, that just isn’t good enough anymore - it also has to be equipped for Industry 4.0 applications. This modern-day requirements profile presents no problems for the new Blue e+ chillers from Rittal, a liquid-based cooling solution for machines and process plants. In addition to the Blue e+ chiller, the system supplier for enclosure technology is also showcasing a range of additional innovations at EMO Hannover 2017.

    Along with the aforementioned attributes of the Blue e+ chiller generation, there have also been huge advances in energy efficiency. This significant reduction in energy consumption is based on the use of a speed-regulated compressor. On a hot gas bypass control system, the refrigeration compressor is run at full load permanently, which results in a large proportion of the cooling power being destroyed without ever being used. By contrast, the DC refrigeration compressor in the new system is regulated by an inverter so that it can supply cooling power to precisely match current requirements. This keeps hysteresis extremely low without wasting cooling power unnecessarily.
