Get your controls off the wall and onto your pumps
Savvy engineers and mechanical contractors know there are numerous benefits from using intelligent Design Envelope pumps from Armstrong, including their utilization of intelligent variable speed controllers (IVS) mounted directly on the pump instead of on the wall. Here are the top three.
Lower Installation Costs
Armstrong controllers are built into the pump, so no additional wiring or electricians are required to install, saving you hundreds of dollars per pump.
Additionally, you won’t need to allocate wall space to mount external controllers, nor will you have the headache of having to wire them.
Increased Energy Efficiency
In a chilled water system, a building’s temperature controls influence the local flow of control valves modulating flow to the cooling coils (load). As the control valves open for more chilled water flow, the differential pressure across the valve decreases. Armstrong controllers react instantaneously to this change by increasing the pump speed. If the control valves close to reduce the chilled water flow, the differential pressure across the valve increases and the controller reduces the pump speed and draws only the power required to meet that demand.
As a result, the “intelligent” action of Armstrong IVS saves energy every minute the pump is on: the drive and the motor are mated/configured to work better together, resulting in ideal pump efficiency vs. the need for increased speed, horsepower and energy. Armstrong Design Envelope pumps feature the largest impellers available, which are more efficient, so you don’t need to run a trimmed impeller at full speed. This requires less energy and gives you more flexibility in the capability of the pump.
Armstrong IVS also supports ASHRAE 90.1 energy saving targets.
Lower Maintenance Costs
Pump-mounted controllers experience fewer problems than wall-mounted controls because of better integration and enclosed wiring. This results in a lower maintenance cost over the life of the pump.
Having integrated controllers also means that when there is a pump issue, you have a single source to troubleshoot instead of having to call multiple parties who blame each other. This makes it easier to identify the root cause(s) of the problem – i.e., not enough flow, closed valves, air in the system, or an issue with the controller.
