Automatic expansion vessels with mass transfer are part of pressurization advanced dynamic systems. They are controlled by an air compressor which guarantees a steady pressure in the circuit, compensating fluid volumetric changes due to changes in water temperature of the system. By the use of a microprocessor, installation parameters are controlled and regulated, displayed by a 7 “ touch screen. The control unit from CRB AUTOMAT models has been developed under the brand IBAIONDO and offers the most modern connectivity interfaces (RS - 485 & Ethernet).
