Deployed System Outcomes

Documented results from control system installations across three facility types

Data Center

Tier III Colocation Facility — 2,400 kW Cooling Load

A North American colocation operator with three campus buildings running legacy pneumatic controls faced PUE above 1.8 and frequent hot-spot incidents. Emerson deployed 1,200 IoT sensor nodes, replaced existing controls with BACnet-networked DDC controllers, and implemented dynamic airflow balancing across 48 CRAH units. Within 12 months of commissioning in 2023, monitored PUE dropped to 1.38 and cooling energy expenditure decreased by 31% — verified against utility billing data from the previous 24-month baseline period.

Pharmaceutical

GMP Cleanroom Complex — 8 Validated Zones

A European pharmaceutical manufacturer operating ISO Class 7 cleanrooms for injectable drug production needed 21 CFR Part 11 compliant monitoring after a regulatory audit finding in 2022. Emerson installed validated temperature and differential pressure monitoring across 8 production zones with redundant sensor arrays and automated deviation reporting. During the first 18 months of operation, the system generated 4 predictive alerts for compressor bearing degradation, each resolved during scheduled maintenance windows with zero unplanned production interruptions.

Commercial Office

14-Floor Corporate Tower — 85,000 m² Mixed Use

A Middle Eastern commercial real estate group managing a mixed-use tower with highly variable occupancy patterns (30-95% depending on floor and time of day) required zone-level demand-controlled ventilation. Emerson deployed occupancy sensors on all 14 floors tied to CO2-based ventilation modulation and chilled water valve sequencing. Post-commissioning monitoring from Q2 2024 showed HVAC runtime reduction of 22% and chiller plant COP improvement from 3.1 to 4.2 at average part-load conditions — tracked through the building's sub-metering infrastructure.

Frequently Asked Questions

Our controllers support BACnet IP/MSTP, Modbus RTU/TCP, LonWorks, and KNX protocols. The cloud gateway adds MQTT and REST API connectivity for IoT integration with major cloud platforms including AWS IoT and Azure IoT Hub.

Yes. Our open-protocol architecture is designed for retrofit scenarios. We provide protocol converters, integration middleware, and on-site commissioning support to connect with Siemens, Honeywell, Johnson Controls, and other legacy BMS platforms.

Based on post-commissioning energy audits across 120+ sites commissioned between 2019 and 2025, facilities typically see energy cost reductions of 20-35% within the first 12-18 months. The full system payback period ranges from 2-4 years depending on facility size (optimal range: 10,000-100,000 m²), climate zone (ASHRAE zones 1A-5A show highest savings), and the efficiency baseline of existing equipment being replaced.

Our EEV range is validated for R-290 (propane), R-744 (CO2), R-32, R-1234ze, and R-454B. Each valve model includes refrigerant-specific flow coefficients and superheat control parameters, pre-configured in our commissioning software.
