Armstrong Fluid Technology has introduced a new version of its Design Envelope pump to serve light duty installations where the available power is single phase.
The new Design Envelope pumps are available for use with single phase power (200-230V) from 1/3 to 2hp and are built to a design standard carried over from commercial pumps. In addition, because the mechanical room piping for light-duty fluid-flow applications is often installed vertically, these new single-phase pumps can be installed and operated in vertical piping.
As with all Design Envelope pumps, the technology is built around a demand based intelligent control solution that models equipment and system behaviour, monitors actual system conditions, dynamically adjusts equipment operation to match system demand and is designed to provide high levels of energy efficiency and low installation and operating costs.David Lee, program manager, Product Development, Armstrong Fluid Technology, said: “Many light-commercial and residential buildings use single phase power and some mechanical rooms ‘step down’ three phase power to make single phase power available. These new pumps provide a practical and economical solution for those installations.”
