Overview
Armstrong's Integrated Pumping System (IPS) is designed to automatically deliver the required pumping capacity to match building loads while minimizing energy costs. It uses system load detectors, such as differential pressure sensors, to adjust flow rates and maintain efficiency.

System Specifications
The IPS can control up to six pumps in parallel and accommodate up to eighteen remote system load sensors. It supports variable frequency drives (VFDs) with or without power bypass systems. The system is capable of operating pumps in a 100% standby mode or in a staged parallel sequence.

Performance and Energy Efficiency
The IPS is suitable for both constant speed primary and variable speed secondary systems. It ensures system performance at the lowest cost by maintaining the design differential pressure across control valves. The system's precise control of condenser differential temperature enhances chiller efficiency and reduces pumping costs.

Operational Cost Reductions
Variable speed pumping in variable flow systems leads to significant energy cost reductions compared to constant speed pumping. The IPS's Direct Digital Control (DDC) maintains pump speed within 1%, maximizing energy savings.

Technological Features
The IPS 5000 and 9000 models feature a touch-screen interface for easy access to settings and operational data. The system supports digital communication protocols like Modbus, LonWorks, BACNet, and MetaSys Open N2 for integration with Building Automation Systems (BAS).

System Responsibility and Support
Armstrong provides comprehensive support for IPS installations, including design assistance, component selection, and on-site operator training. The company ensures a reliable and energy-efficient system design.

Controller Models
The IPS family includes models 3000, 5000, and 9000, each offering different functionalities and control limits. Features include variable secondary control, speed matching on pump staging, and chiller sequencing.

General Sequence of Operation
The IPS automatically adjusts pump speed to match load requirements, using a closed-loop DDC control for precision. It ensures smooth transitions during pump staging to prevent surges. The system continuously monitors energy consumption to optimize efficiency.

Conclusion
Armstrong's IPS offers advanced solutions for demanding pumping applications, ensuring energy efficiency and reliable performance.
