Integrated Pumping Systems (IPS) - Armstrong's IPS automatically ensures delivery of required pumping capacity to match key building loads, while maintaining pumping energy costs at a minimum.

With the use of system load detectors, such as differential pressure sensors, at one or more remote load locations, the Armstrong IPS automatically and continuously provides just the required flow for the current needs. HVAC system load requirements vary considerably during a typical day. Considerable energy savings result when pumping capacity is continuously matched to the load.

Pumps may be operated as 100% standby or in a multiple pump, staged parallel sequence. Armstrong's IPS can control as many as six (6) pumps in parallel, with up to eighteen (18) remote system load sensors.

Dedicated Variable Frequency Drives (VFDs) may be used, with or without power bypass systems. Armstrong offers the most advanced IPS available, with the flexibility to meet the most demanding pumping applications.

Armstrong's IPS concepts should be considered for constant speed (CS) primary with variable speed (VS) secondary, or VS primary heating and cooling systems, condenser system differential temperature and differential temperature across the chiller plant.

Ultra-Efficient Chilled Water Integrated Plant Control (IPC 11550) - The IPC 11550 system creates a new standard for HVAC system communications, with full remote control capabilities through web-based interfaces. In addition to helping predict equipment failures, the all variable speed IPC 11550 system helps avoid system failures, as operating at a lower speed will extend equipment life.

The IPC 11550 system employs the Hartman LOOP® Natural Curve sequencing logic to ensure that the variable speed chillers are always operating as close as possible to their maximum efficiency.

“All variable speed” plant control offers the greatest opportunity for energy savings. Using the IPC 11550 you will be able to achieve annual average efficiency levels that are twice that of today’s best-in-class systems. The IPC 11550 System also provides secure, remote plant assessment, easily downloadable plant data, operator assistance with plant alarms, protocol translation between field hardware and the BMS, scalability for future plant extensions and the world’s most user-friendly touch-screen interface.

Circulator Isolation Flanges - Armstrong Circulator Isolation Flanges (CIF) are used in pairs to connect circulating pumps in hydronic systems. These devices rapidly isolate a circulator to be serviced, and eliminate the need to drain and refill the entire system. The CIF integrates a 2-bolt flange connection (common to small circulating pumps) with a full-port ball valve. This practical "all-in-one" design reduces the number of plumbing connections and results in a more reliable, economical and easily-serviced hydronic system.

Flex Flanges - Flex flanges help make initial circulator installation easier and future maintenance faster. The rotating flanges eliminate the need for perfect alignment before circulator installation and the integral check valve saves two pipe connections compared to a separate check valve. Additionally the dielectric flange coupling helps reduce pipe corrosion by avoiding contact of dissimilar metals. For future servicing ease, the integral ball valves enable the circulator to be isolated from the system for removal or replacement, without draining the entire system.
