The Armstrong IVS Sensorless pump is designed to meet the need for energy-efficient pumping systems in today's buildings. Traditional smaller pumping systems, up to and including 10 hp, incorporating fixed-speed pumps waste energy through crude throttling valve flow control. Lifetime Cost Analysis shows that the capital cost of a fixed-speed pump is typically only 5% of its lifetime cost.
The IVS Sensorless pump is a new generation variable-speed pump, completely integrated into a compact package. Pressure transducers/sensors are no longer required, which reduces the installed cost of the unit and makes it practical to use these IVS variable-speed pumps in a retrofit installation.
Applications for this technology include variable volume heating and chilled water applications. The design of the Armstrong IVS Sensorless pump goes beyond ASHRAE 90.1 standards, providing the benefits of variable speed technology for motor sizes below 10 hp.
- Variable speed technology allows the speed of the pump to be tuned to suit system demand.
- Technological advancements make variable speed pumps attractive in terms of both capital and lifetime cost.
- Pressure transducers/sensors are no longer required, further reducing capital and installation cost.
- The IVS Sensorless pump is a new generation pump, completely integrated into a compact package.
- Applications for this technology include variable volume heating and chilled water applications.
- Goes beyond ASHRAE 90.1 standards by adding value through varying pump speed with 10 hp and lower motor sizes.
