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.

CRB AUTOMAT control unit has been developed under the brand IBAIONDO and offers the most modern connectivity interfaces (RS – 485 & Ethernet).
