Danfoss ABQM Pressure Independent Balancing and Control Valves (PIBCV)

Wednesday, 25 July, 2012 | Supplied by: Devex Systems

Devex Systems has released the ABQM Pressure Independent Balancing and Control Valve (PIBCV), a high-efficiency balancing solution for heating and cooling systems, manufactured by Danfoss.

Without pressure independent technology, it can be extremely challenging to maintain the balance of an HVAC system, but ABQM’s technology has now simplified this process through combining a compact automatic balancing valve and a control valve into one comprehensive valve structure. This results in good temperature control and performance and energy savings.

A recent test case was performed by Devex Systems and Danfoss at the University of Technology, Sydney, comparing two rooms of identical size, heat load and dedicated fan coil units; the control room was unchanged from its classic control (control valve plus manual balancing valve) while the other room was retrofitted with the ABQM valve to replace the control and manual balancing valve.

The findings were such that the room using ABQM had 25% energy savings and maintained a much more even and controlled climate, eliminating drastic temperature spikes throughout the day.

The efficiency and cost savings that can be achieved using this product has spurred the interest of engineers, specifiers and end users, including those in the field of building services/maintenance. The valve reduces system pumping costs and improves system heating/cooling equipment efficiency. It can be used in retrofit as well as new construction projects and is a good solution for controlling terminal units such as fan coils, chilled ceilings and air-handling units.
