Air-Cooled & Water-Cooled Rotary Screw 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 Slide valve position linear feedback voltage and capacity loading/unloading solenoids, Compressor discharge temperature and oil separator differential pressure, Oil sump level optical switch and oil heater temperature controller—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.

Real-time slide valve positioning optimization matching partial-load requirements without wasteful short-cycling or hunting. 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 25 Days Warning, predicting root causes such as Screw compressor capacity slide valve hydraulic hunting, mechanical sticking, and leakage, Shaft mechanical seal elastomer degradation causing lubricant and refrigerant loss before mechanical damage propagates.

Optruss features pre-configured kinematic signatures, vibration tolerance envelopes (AHRI 550/590 / ASHRAE 90.1), and thermal failure models for leading global manufacturers including Daikin Applied, Trane, Carrier, York, Dunham-Bush. 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 Industrial Polymer Extrusion Cooling, Brewery & Beverage Fermentation, Medium Hospital Complexes, Commercial Campus Chilled Water. Field deployments validate an average +38% MTBF MTBF extension, +11% part-load energy efficiency (IPLV) and -40% reduction in slide valve hydraulic actuator overhauls., and substantial reduction in unplanned maintenance costs. Critical alerts trigger automated CMMS work orders with OEM spare parts reservation.
