Danfoss AB-QM - pressure independent balancing and control valve
A time for change
The control and Hydronic Balance of installations is often based on concepts developed more than thirty years ago.
These concepts are not able to comply with modern demands for comfort and energy efficiency. Danfoss has created a valve that reduces the amount of time spent on calculations, installation and commissioning. This valve, the Danfoss AB-QM, does all that for you while optimising the system to give maximum comfort and minimum energy consumption.
Full range
The Danfoss AB-QM pressure independent balancing and control valve (PIBCV) was introduced a few years ago and enjoyed significant success, as our long list of references and success stories shows. The AB-QM product range has been extended and the range now covers DN 10 up to DN 100. The AB-QM can now handle all applications, whatever their size.
The Danfoss AB-QM is a money-saving device:
• Fewer products, so less installing to do
• Easy sizing, so fewer calculations
• Set and forget, so no commissioning
• Better comfort, so fewer complaints and less service required
• Always the right flow, so no energy wasted
Often reducing costs means a trade-off: You have to sacrifice something, like comfort or quality, in order to make the savings.
The Danfoss AB-QM reduces the costs and raises the quality of the installation, it's a real win-win situation.
Example: Installation
In a traditional system you would use a 2-way control valve and a manual balancing valve to limit the flow and control the room temperature. The AB-QM PIBCV can replace the control valve and the manual balancing valve. While at lower loads the balancing valve is static and loses its function, the AB-QM realises the ideal flow for all loads.
AB-QM conclusion:
Fewer products, fewer problems, lower costs.
