Armstrong Fluid Technology: Vertical-In-Line Pump Retrofit
The Design Envelope Vertical-In-Line Retrofit allows building owners to replace the moving parts of an installed Armstrong constant speed pump while retaining the existing pump casing, insulation, and piping. Upgrading to variable speed operation means longer equipment life (20-30 percent), up to 70 percent savings in energy costs, and greater reliability. Design Envelope solutions don’t require differential pressure sensors, wall-mounted drives, or additional wiring, and, because the solution reuses the existing casing, there's no need for a pressure test after the installation. With all of these savings in installation time, labor costs for the retrofit project are kept to a minimum.
