Pre-Fabricated Flushing Bypass Assembly for Terminal Applications
Mini-Flush 40
with
Description
Miniflush 40 is a pre-fabricated, flushing bypass arrangement for balance, control, isolation, and
operation of terminal devices. It is designed for use with fan coil units, chilled beams, and other
terminal devices, where flow is controlled via a pressure independent control valve, and isolation,
drain, flushing bypass, and flow measurement is required.
Key features include:
• A compact, pre-fabricated design
• Factory pressure tested assembly
• Each assembly is labelled with FCU location and Miniflush 40 instructions
• High flow DN15 option for direct connection to CHW terminals with flows up to 0.315 l/s
• Low flow option for LTHW flow rates down to 0.008 l/s
• Left and right handed versions to prevent clashes within the fan coil
• A wide range of connection options, including BSP, compression, and solder connections to the
coil
• Danfoss AB-QM pressure independent control valve for balance at full or partial loads
• A comprehensive compatible range of actuators to enable it to be connected to a building
management system or other controller
• Flow mounted drain for flushing and quick drain-downs
• Flow measurement function in all sizes

Operational Modes
Normal Operation
This is the supply operation of the Mini-flush,
with flow going through terminal, and out
through the return, back to the system.
The AB-QM valve will balance by limiting the
flow to the coil, and the actuator will control
flow as per the temperature requirement.
Flushing
During system flushing, the terminal will be
isolated, but a flow around the main system is
required. To enable bypassing we have
positioned a flushing bypass within the Miniflush assembly, which can open a link between
flow and return, to enable mainline system
flow for flushing.
Back Flushing
To enable flushing through the terminal, the
return can be opened, with the flow and
bypass isolation valves closed. The drain is
then opened, to allow flow through the coil,
and any coil debris will be released through
the flow side drain point.
Isolation
For a variety of reasons, it may be required to
completely isolate the terminal. For this we
can isolate the flow and return, and close the
bypass, to remove all flow through the coil
and bypass.
