New Design Envelope Tango Ensures Uninterrupted Service, Even During Maintenance
Armstrong has introduced new larger sizes of the Design Envelope Tango, a compact, low-carbon dual pump that ensures uninterrupted service, even during maintenance. The Design Envelope Tango includes two motors and two impeller assemblies in a single casing. Integrated valves can isolate one side of the pump for service, without interrupting flow or affecting occupant comfort. New sizes are now available with motors ranging from 11 to 30 kilowatts (15 to 40 horsepower) and are capable of serving applications up to 160 feet of pressure (2000 GPM).
Design Envelope Tango is a compact solution that combines built-in redundancy with leading performance and reduced installation costs. Because the two rotating devices share a single casing, installation requires less piping. In addition, the Vertical In-Line orientation means the pump is installed in the piping and does not require an inertia base.
Design Envelope technology includes patented Parallel Sensorless operation, increases flow turn-down and provides built-in flow metering for superior flow control. The energy-efficient design of the Tango reduces operating costs by up to 80% and lifecycle costs by up to 40%.
The value of Design Envelope pumps is augmented by Pump Manager, a cloud-based service that provides smart analytics, diagnostics, and alerts to support HVAC system efficiency. All Armstrong 360 Service and Support programs optimize the lifetime performance of HVAC systems.
