  • AQA therm HES for MOVE Power

    AQA Therm HES

    The AQA therm HES, is designed to be installed immediately after HFB Connection module. This multi-function module incorporates an electric water meter with liquid crystal display, a docking station for the optional water treatment cartridges and the AQA therm adaptor, a shut-off ball valve and a treated water filling point (Note: non-potable water!).

    This module can be used with the appropriate cartridges for softening or desalination of local source water ensuring only optimized water is used for filling or re-charging your heating circuit. The electric water meter can register and display the flushing, filling and refilling volumes accurately.

    The AQA therm HES works equally well with the AQA therm HRC hardness-reducing cartridge, using the principle of ion exchange, or with the SRC desali­nation cartridge which reduces both calcifying and corrosi­ve substances in the water.

    By using the AQA therm adaptor and appropriate connectors the HES can also be used successfully with the AQA Therm Move Power as a convenient connection point into heating circuits that need to be filled with larger volumes of high purity RO water.

  • AQA therm HFB for MOVE Power

    AQA therm HFB

    At the heart of the AQA therm HFB BA is a backflow preventer, pressure reducer and two shut-off ball valves. It has been designed and developed as part of the AQA therm HWG modularized system to provide a safe and standardized connection between the heating circuit and the drin­king water supply.

    The HFB protects your normal water supply from the risk of contamination by stopping any back flow of system water into your drinking water supply. For this reason, it must be permanently connected between your normal water supply, and the heating system this allows it to be refilled safely at any time.

    The backflow preventer is a double check valve compliant with DIN EN 1717 designed specifically to prevent the return of polluted water into the supply line, external systems or other system compo­nents.

    It includes the following components:

    • Heating filling block
    • Integrated backflow preventer that prevents back flow of heating water into the drinking water system
    • Integrated filter for filtered water to standards
    • Built-in pressure regulator (1.5 bar pre-set, manometer, barrier, cladding)
