Pre-Fabricated Flushing Bypass Assembly for Terminal Applications Mini-Flush 40

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

Notes:

-The recommended flow rates are to enable accurate measurement of flow -Actuators need to be ordered separately

-Options are available for connection to the pipework and terminal. Please discuss with your representative prior to ordering

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.
