Armstrong Fluid Technology’s Design Envelope vertical-in-line retrofit allows building owners to replace the moving parts of an installed constant-speed pump while retaining the existing pump casing, insulation and piping. This solution reduces the costs for equipment, shipping and scrap as well as installation labor. The technology accommodates future changes in flow requirements and its variable-speed operation means longer equipment life (20-30%), and greater reliability, Armstrong notes.
