Eisele expanded the LIQUIDLINE by designing two energy-optimised coolant connections that exceed the outstanding flow rates of the previous LIQUIDLINE connections by an additional 15 to 20 percent. In addition to the existing 45 and 90 degree angle connections, the supplier now offers a connection in which the threads are connected with the release sleeve by means of a 45-degree or a 90-degree angle piece made of copper pipe. The two new coolant connections are good for high-performance applications in which it is necessary to achieve the maximum possible flow capacity. If in addition to the flow rate an especially good seal of the connections is decisive, the plug-in connections of the LIQUIDLINE 2400 series with two seals might be the right choice. They are so reliable that they can even be used directly in the control cabinet or cleanroom and are designed for operating pressures from -0.95 to 24 bar, in some applications even up to 100 bar. For cooling water applications with low pressure from -0.95 to 16 bar are with the series 2600 of the LIQUIDLINE simpler plug-in connections with release sleeve and only one seal available. They are also suitable for vacuum.
