Optimizing Large Chiller Systems

Deviations from published equipment specs, piping idiosyncrasies, load profiles and individual system operating limits mean every system operates differently. Larger plants typically require a high level of support. That’s why Xpress® Pro includes complete design support, baseline development generation, utility rebate assistance, and remote monitoring and diagnostic services.

Xpress®: Built on Adaptive Optimization Algorithms

tekWorx system optimization modules work together to balance air distribution and chilled water production to maximize total system efficiency.

Air Distribution

Based on tekWorx powerful CEO® technology, this package continuously and automatically minimizes the power required for air distribution and delivery. Proven adaptive control techniques optimize air pressure, flow and temperature (system and zone) while maximizing economization mode and meeting desired space conditions.

Cooling Production & Distribution

These optimization algorithms are responsible for providing efficiency-based chiller plant production equipment calls and chilled water process control setpoints. The CPM will coordinate equipment sequencing and resetting the system setpoints to minimize total cooling system energy usage, thereby optimizing overall system efficiency

Heat Rejection

Optimizes system efficiency by optimizing condenser water process parameters along with pump and cooling tower operation. When water side economization is available, the HRM optimizes mode transition and heat exchange flow and temperature.
