Rittal Blue e+ chillers

Jun. 23, 2017 – The temperature of the cooling medium in machine tools needs to be controlled accurately so as to ensure high-precision machining. The cooling system must also be energy-efficient, versatile, reliable and easy to maintain. Rittal says it has factored these requirements into the development of a new generation of Blue e+ chillers.

The result is a liquid cooling system for process plant and machinery that sets a new market standard. Cooling accounts for up to 15 per cent of a machine tool’s entire power consumption. Rittal says its new Blue e+ series is a chiller generation that enables a huge leap in energy efficiency. According to the company, an Energy Efficiency Ratio (EER) of 3 is possible with the Blue e+ chillers. As well, its drive and control technology results in energy savings of up to 70 per cent compared to chillers with hot gas bypass control systems, says Rittal. The chillers are available in three performance classes with cooling outputs of 2.5, 4 and 6 kW (adjustable between 20 and 100 per cent).
