** The IVS control is a low harmonic control with a built-in DC link reactor equivalent in performance to a 5% AC line reactor. This
does not guarantee performance to any system wide harmonic specification or the costs to meet a system wide specification. If
supplied with the system electrical details, Armstrong will run a computer simulation of the system wide harmonics. If system
harmonic levels are exceeded, Armstrong can also recommend additional harmonic mitigation and the cost for such mitigation.

Design Envelope pumps offer industry-leading efficiency and performance management capabilities for significantly reduced
energy consumption. Armstrong has undertaken a multi-year project to transition our pump offering to an integrated design
that use Design Envelope Permanent Magnet technology for even greater operating cost savings. In the sizes currently
equipped with Design Envelope Permanent Magnet motors, the pumps are also more compact and lighter than our standard
Design Envelope pumps.
Please note that depending on the pump sizes, your shipment may include a combination of:
* Design Envelope Permanent Magnet pumps
* Design Envelope Permanent Magnet pumps with IVS controls
* Design Envelope Pumps with Premium efficiency induction motors and IVS controls
