The Hydrun Pressurisation / Degassing Combo combines dynamic pressure maintenance and vacuum degassing in a fully automatic unit. It ensures the correct system pressure at all times—and once the pressure is stable, it removes dissolved gases via a bypass flow for quieter, smoother, and more reliable heating and cooling system operation.
Clear connection logic and preset values reduce time on site.
Removes dissolved gases and microbubbles, reducing corrosion, cavitation, and wear in the system.
Proven, service-friendly components from Grundfos, Danfoss, and Schneider Electric.
Modbus TCP, RTU, and BACnet for alarms, status, and logging directly to the BMS/DDC as standard.
The unit can be installed with both open and closed expansion vessels.
Function and performance verified in independent tests by the Research Institutes of Sweden.
Swedish manufacturing with traceable quality, short lead times, and prompt access to spare parts.
