Predefined hydraulic loops (i.e. prefabricated blocks of grouped elements having one pair of inputs and outputs each) are available in the hydraulic control loops cataloques for the InstalSystem package. They may include, for example, a pump, balancing valves (including PIBCVs), control valves and overflow-relief valves. Hydraulic control loops are mainly used to hydraulically balance and regulate (qualitatively or quantitatively) the thermal efficiency of the end receiver (usually a fan-coil or cooling beam). They can also be used in heating systems. Hydraulic control loops are not graphically editable and allow the use of valves and fittings only from a list of items suitable for use in a given location. The configuration of the hydraulic loops is created in close cooperation with the valve producer, which guarantees correctness and eliminates the risk of using the wrong types of valves and thus making design errors. Once a predefined hydraulic control loop has been inserted into designed installation, all its components are taken into account during the calculation and shown in the automatically generated bills of materials.
The InstalSystem package includes extended library of hydraulic control loops companies catalogues (check the list: Partners offering company versions of programs and catalogues).
