Coolant circuits must dissipate heat from applications such as welding or power-electronics installations. This requires high flowrates within a compact space. This company has extended its Liquidline by designing two energy-optimized coolant connections that exceed the flowrates of previous Liquidline connections by an additional 15%. In addition to the existing 45- and 90-deg angle connections, the company now offers a connection in which the threads are connected to the release by means of a 45- or 90-deg angle piece made of copper. — Eisele Pheumatics GmbH & Co.
