One of the most important trends in building construction and building management is the continuing focus on energy efficiency, because of it’s impact on climate change and on customer operating costs.
Intelligent, variable speed fluid management has emerged as a significant energy-saving technology, with Armstrong Fluid Technology at the forefront of this change with Design Envelope.
Because energy and cost savings can reach up to 70% with the new technology, pump owners see an opportunity to reduce operating costs and improve profitability with variable speed equipment. Now with the new Armstrong Design Envelope Vertical-In-Line Retrofit, they can upgrade existing Vertical In-Line (VIL) constant speed Armstrong pumps. They simply install a new Design Envelope rotating assembly, consisting of integrated motor, controller, shaft, impeller, adapter, flush line, seal and casing gasket.
Keep the old casing, piping and pipe insulation in place, while replacing the moving parts in our older VIL pumps, upgrading them to intelligent, variable speed Design Envelope technology.
There are numerous benefits to this program including:
Energy savings are so significant that paybacks are typically 2-3 years (60% – 70% savings with Design Envelope variable flow). After this short payback period the client enjoys these annual savings each and every year.
Equipment, shipping and scrap costs that are reduced because you re-use the casing.
Labor cost is less than half (of a complete new variable speed pump) because you use existing piping and insulation, and no pressure test is required. Downtime is reduced too. In general, it’s a much less intrusive procedure than a complete replacement.
