Company: Armstrong Fluid Technology

Product: Design Envelope Vertical-In-Line Retrofit

Description: This retrofit unit allows building owners to replace the moving parts of an installed Armstrong constant-speed pump while retaining the existing pump casing, insulation, and piping. The Design Envelope technology accommodates future changes in flow requirements, and its variable-speed operation means longer equipment life and greater reliability. Design Envelope solutions don’t require differential pressure sensors, wall-mounted drives, or additional wiring, and, because this product reuses the existing casing, there’s no need for a pressure test after the installation.
