Variomat GigaPressurisation SystemsDiaphragm Expansion VesselsVariomat Giga with basic and secondary vessels on the heating systemPressurisation SystemsVariomat Giga• Pump-controlled pressure maintenance for particularly high outputsand pressures. For example, in district heating systems and industrialheating and cooling supplies• Designed for the highest level of reliability• Special systems for temperatures > 110 °C and vessel volumes of upto 20,000 litres possible• A Variomat Giga always consists of the control unit, the hydraulicmodule, the vessel and, if necessary, further options• Larger expansion volumes can be implemented, both in accordancewith large vessels as well as through a serial circuit of a basic vesseland one or several secondary vessels41
