Demand Flow

Siemens Demand Flow® optimizes chilled water systems to enhance comfort, cut energy costs, and sustain operational efficiency. This patented, automated solution leverages built-in analytics to reduce internal workload and extend equipment life for lasting value.

Beat your operational challenges with Demand Flow

A system that’s operating below peak efficiency is likely to cause energy waste and increase your costs. Poor system performance and failures can be caused by a flawed design or by poor operation and maintenance but also by global weather trends and unpredictable patterns. Whatever the cause, the impact is increased energy use and costs and can affect the comfort and productivity of occupants. Demand Flow for chilled water (CHW) systems is a holistic application of thermodynamic principles that quickly resolves operational issues. It was developed using our decades of experience in optimizing chilled water systems to solve your challenges.

A holistic Demand Flow approach to optimize your system

Demand Flow uses intelligent, powerful, and proven methods to enhance system performance, energy efficiency, and occupant comfort.

The graphic includes a central needle, three small downward-pointing arrows above the gauge, and a grid of small dots to the right, suggesting performance, metrics, or progress tracking.

Reduce downtime

Reduces the risk of unexpected downtime, lowers costs, and extends your equipment’s expected lifespan.

Extend equipment lifespan

Increased deliverable tonnage provided by Demand Flow results in more redundancy. Reduced run-time means less maintenance and wear and tear.

Improve indoor environmental quality

Increases occupant comfort and offers more effective humidity control. It requires less energy to deliver potentially colder chilled water temperatures.

Simplify system operation

Sequencing chillers in Siemens Demand Flow is typically lead/lag based on run-hours, which can be customized for intuitive sequencing of equipment and improved system reliability and control.
