蓄能器气体与液体不接触的称为HYDAC隔离式蓄能器，常用皮囊和隔膜来隔离，皮囊体积变化量大，隔膜体积变化量小，常用于吸收压力脉动。重锤式容量较大，常用于轧机等系统中，供蓄能用。

    德国HYDAC蓄能器工艺过程技术：特殊介质过滤器、自动反冲洗过滤器。 电子测量技术：压力、温度、流量检测开关、传感器及显示器、故障诊断仪等。冷却技术： 油/风冷却器、水冷却器，各类冷却装置，供油泵。

    德国HYDAC蓄能器中的压力可以用压缩气体、重锤或弹簧来产生，相应地蓄能器分为气体式、重锤式和弹簧式。HYDAC气体式蓄能器中的气体与液体直接接触者，称为接触式，其结构简单，容量大，但液体中容易混入气体，常用于水压机上。

    HYDAC贺德克产品的应用范围十分广泛，几乎覆盖各行各业，尤其在冶金工业、汽车工业、电力设备、化工、工程机械、造纸工业、造船工业以及机床制造等领域都得到广泛应用。
