High-Tonnage Water-Cooled Centrifugal Chillers: Telemetry Ingestion, Physics AI & Reliability Architecture

Optruss connects non-intrusively using read-only industrial protocols including OPC-UA, Modbus-TCP, Profinet, and MQTT Sparkplug B. Telemetry from existing instruments—monitoring Evaporator and condenser water inlet/outlet temperatures and flow rates (RTDs & magnetic meters), Refrigerant suction, discharge, and intermediate economizer pressures (bar), Centrifugal compressor motor electrical kW, current, and variable inlet guide vane (VIGV) position—is streamed across hardware-enforced unidirectional data diodes into sovereign edge enclaves. High-frequency vibration and dynamic pressure are sampled at up to 102.4 kHz to capture micro-spalling and transient acoustics without injecting latency into DCS control loops.

Thermodynamic refrigeration cycle COP regression modeling approach temperatures to detect refrigerant leakage and tube scaling independent of chiller load. By fusing mechanical first principles (affinity laws, thermodynamics, and rotor dynamics) with deep neural networks, Optruss eliminates false positive trips common to purely statistical anomaly detection. The system provides an early warning horizon of 30 Days Warning, predicting root causes such as Centrifugal compressor aerodynamic surge under low condensing water temperature, Refrigerant charge loss past shaft mechanical seal causing low evaporator suction pressure before mechanical damage propagates.

Optruss features pre-configured kinematic signatures, vibration tolerance envelopes (AHRI 550/590 / ASHRAE 90.1 / ISO 10816-3), and thermal failure models for leading global manufacturers including Carrier, Trane, York (Johnson Controls), Daikin Applied, Mitsubishi Electric. Integration is vendor-agnostic and does not require proprietary OEM software gateways, allowing unified fleet-wide condition monitoring across mixed-vendor operating plants.

This telemetry model is deployed across heavy continuous process facilities in District Cooling Plants, Airport Terminals & Megaprojects, Hyperscale Data Centers, Pharmaceutical Manufacturing Plants. Field deployments validate an average +42% MTBF MTBF extension, +9.4% seasonal energy efficiency (kW/ton reduction) and complete elimination of destructive compressor surge trips., and substantial reduction in unplanned maintenance costs. Critical alerts trigger automated CMMS work orders with OEM spare parts reservation.
