Description

Grundfos mixing unit MIXIT 25-6.3 NRV right bypass cod. 99508818

Model: MIXIT 25-6.3 R NRV

Grundfos MIXIT is a complete prefabricated mixing circuit with integrated control functions designed for heating and cooling systems.

MIXIT is mainly suitable for three-way installations in large buildings, such as schools, without the need for monitoring, pressure independence or balancing.

With MIXIT, a complete mixing circuit is built with just two components: a MIXIT valve unit and the best-in-class MAGNA3 circulation pump from Grundfos.

Since MIXIT communicates wirelessly with the MAGNA3, only two power cords are required for the MIXIT system to operate.

The compact design ensures maximum space utilization and a neat and compact installation.

MIXIT has an integrated actuator and controller and integrated flow and temperature sensors.

Thanks to the uniquely designed valve and real-time sensor measurements, MIXIT ensures precise flow temperature control even at low flow rates.

The threaded versions of MIXIT have an integrated removable non-return valve.

Non-return valves are available as accessories for flanged versions.

MIXIT is controlled via an intuitive operating panel and communicates wirelessly with Grundfos GO Remote for easy setup and control.

MIXIT can be configured via three I/O terminals and two relay outputs.

The MIXIT system can operate as an autonomous mixing circuit in buildings without additional equipment. Fieldbus (BACnet, Modbus or GENIbus) via RJ45 Ethernet and RS485 transceiver ensures easy BMS integration, allowing MIXIT to also function as a subsystem in larger buildings.

MIXIT offers all the functions necessary to adapt the mixing loop to your system, including the following:

  • Temperature control
  • External setpoint reduction for radiator heating systems
  • Underfloor overheating protection for underfloor heating systems
  • Coil preheating and freeze protection for air handling unit systems
  • Pump control mode for all heating and cooling applications
  • Outside temperature compensation
  • Eco program and shutdown during the hot season.

MIXIT DYNAMIC also gives you access to Grundfos BuildingConnect Free Monitoring, a real-time monitoring system with alarm and warning notifications.

MIXIT can be combined with the DYNAMIC and CONNECT upgrade.
