Design Envelope technology is a demand based intelligent control solution that models equipment and system behavior, monitors actual system conditions, and dynamically adjusts equipment operation to match system demand. Design Envelope technology is at the core of Armstrong’s groundbreaking advances in building performance. Design Envelope technology enables the greenest, most flexible and most cost effective fluid-flow and HVAC systems on the planet – resulting in both, lowest installed and lowest operating cost with the same equipment.
Industry Leading Capabilities
Armstrong has reinvented and redesigned our pumping solutions to include connectivity and performance management services. Design Envelope solutions provide optimal lifetime efficiency and lowest cost. No other pumping solution offers the same expanded performance range, one touch commissioning, Sensorless speed control, flow monitoring accuracy and operating notifications.

In multi-pump installations, Armstrong's patented Parallel Sensorless Pump Control saves up to 30% more energy over industry-standard pump staging methodologies. Now, Armstrong's Intelligent Motor Technology, certified to IE5 standards and available on 1 to 10 hp models, delivers 3 – 12 % additional motor efficiency.
This adds up to pumping efficiency that is simply unmatched anywhere in the industry.

Optimum life-time building performance
Pump Manager is a performance management service to help operators maintain optimized long-term efficiency.
Unmatched efficiency
- In the 1-10 HP range Design Envelope uses a completely new, fully-integrated design, where every element is optimized for overall performance. The new Armstrong iECMTM motor with integrated controls, delivers IE5 levels of efficiency.
- Tango pumps offer the pinnacle of energy performance and lifetime value with on-board Parallel Sensorless Pump ControlTM , enabling a completely new approach to system and component redundancy
Optimized lifetime performance through real-time insight and action
- Our full line of pump offerings, from 1 hp to 1250 HP, are all delivered with both wireless and wired connectivity, providing both on-site access to real-time performance and pump conditions as well as connectivity to support Pump Manager, an optional performance management monitoring and reporting service
- Real-time pump performance monitoring capability supports extended energy performance of each pump as well as notifications and recommendations based on pump conditions
- industry studies suggest that “as commissioned” HVAC performance can be extended through a program of monitoring and tuning, resulting in energy savings of 10 to 15%
