SA Armstrong Ltd has simplified the selection process for HVAC equipment. Typically we select equipment like pumps, boilers and chillers for a single design day, but in reality HVAC is a part load industry and that design day could be oversized by as much as 20%. A typical HVAC system may only require 40-60% of its total capacity about 95% of the time.
The answer to these part load conditions is the Armstrong Design Envelope concept. Using a combination of intelligent variable speed and demand based controls; you can minimize risk, reduce capital, design and install costs along with increasing your energy savings.
The design envelope concept is currently available on 4300-IVS series pumps, IPP packaged chilled water plants, 6800-IVS series boosters and the ECO*PAK modular boiler system. For a better understanding of the design envelope concept check out this video or visit armstrongpumps.com.
