Armstrong Fluid Technology has launched an automated control solution designed to drive additional energy savings from chiller plant. Interfacing seamlessly with the existing building automation system. t
The Armstrong Opti-Visor controls the key energy-using components of the chiller plant, providing the optimal operating settings for equipment such as water-cooled, variable-flow chillers, compressors, cooling towers and condenser water pumps.
By controlling the chiller plant ‘holistically’, Opti-Visor harnesses valuable energy savings - even where equipment is recently installed. Armstrong Fluid Technology estimates that energy savings of between 15% and 30% can be expected from the chiller plant, meaning a payback period of less than a year. The first live installation of Opti-Visor in the UK, however, provided immediate savings of 42% , indicating that, depending on the application, the potential benefits could be even higher than the company’s quoted estimates.
Armstrong Opti-Visor is an ultra-efficient relational control solution for operation of all-variable-speed chiller plant. It is ideal for retrofit in buildings with chiller plant less than five years old, but is also suitable for new construction applications involving variable primary flow chiller plants and advanced building automation systems (BAS). It is ideal for chiller plants with greater than 3 million ton-hrs of operation per year (1,000 tons at 3,000 run hours per year).
