In the position to make savings
May 1st 2010 Users of pneumatic valve positioners
can now assess the energy efficiency
of their valve installations with a new
calculator from ABB. Based on the
amount of compressed air consumed
by conventional positioners, the
calculator shows how using the latest
smart positioner technology can help
operators reduce their energy costs.
The calculator uses details
including the number of pneumatic
positioners on site, air cost per
standard cubic foot and the
percentage of time spent at a steady
state to calculate the user's current
compressed air energy costs. These
costs are then compared to the
potential savings that could be
achieved using ABB's TZID-C
intelligent positioners, where
compressed air is only consumed
when required. More articles from ABB Ltd: |
