Armstrong unveils new line of outdoor pumps
Design Envelope pumps come with permanent magnet motors with up to 10hp of power that reduce energy consumption by up to 30%
Armstrong Fluid Technology has introduced new Design Envelope pumps with permanent magnet motors and NEMA 4X/IP66 ratings are now available for outdoor installation.
The global HVAC equipment major said the new pumps features advanced performance mapping technology and load-limiting logic, reducing energy consumption by as much as 30% compared to pumps supplied with a loose variable speed drive. Together with new, more efficient pump hydraulics, the new 1-10hp pumps can save an additional 20% compared to competing integrated products with induction motors.
Other features of the new Design Envelope outdoor pumps include covers to protect touchscreen user interfaces from dirt and sunlight; overhead weather shield to protect motor fan from ice seizures; factory-tested, TL-approved NEMA 4X rated controls; available parallel sensorless controls for additional energy savings through best-efficiency staging; and available Pump Manager service to provide pump performance tracking along with alerts, alarms and data storage.
Zeljko Terzic, global offering manager, Pumps, at Armstrong Fluid Technology, said: “The conventional approach to rooftop and outdoor pumps is to install VFDs in a central, outdoor-rated control panel, separate from the pumps. This adds unnecessary costs and requires a larger footprint. Our new Design Envelope pumps feature integrated controls for a reduced footprint and substantially reduced installation costs.”
