Grundfos MIXIT All-in-One Mixing Loop Solution for HVAC Systems
The Grundfos MIXIT solution redefines the mixing loop by combining all components into a single plug-and-play unit, easing mechanical, electrical, and plumbing design while reducing installation and commissioning time by up to 50%. As part of Grundfos iSOLUTIONS, MIXIT integrates the temperature controller, 2- or 3-way valve, actuator, balancing valve, and sensors into one factory-tested component—all you need is the MIXIT unit and a Grundfos MAGNA3 pump.
As an authorized Grundfos Water Pump Dealer in Dubai, we supply the complete Grundfos MIXIT range with genuine warranty and technical support across the UAE.
