The new Design Envelope pumps will be on display at AHR Expo which takes place in Las Vegas from 31 January to 2 February. The new pumps are now available for use with single phase power (200-230V) from 1/3 to 2hp and, for increased reliability, 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 the highest energy efficiency and lowest installed 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.”
