The MiniFlush is a compact, 100% factory-tested flushing bypass assembly designed for fan coil units, chilled beams and other terminal devices on primary heat networks in multi-dwelling buildings, such as commercial projects, apartments and office blocks.
Combining the Danfoss AB-QM pressure-independent flow control, isolation, flushing, drain, and flow measurement into one pre-engineered assembly reduces installation time while helping to deliver reliable commissioning and long-term system performance.
MiniFlush is readily available from your chosen local distributor.
Product range:
Miniflush 40 – 40mm centres
Miniflush 80 – 80mm centres
