Computer Room Air Handler (CRAH) & Precision CRAC Units: 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 Underfloor raised-plenum static pressure sensors (Pa) across cold-aisle zones, Server rack front inlet and rear exhaust temperature arrays (top, middle, bottom), CRAH chilled water valve position feedback (0-10V) and water flow meter—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 thermal digital twin mapping server rack delta-T to dynamically trim EC fan speeds and chilled water valve openings to maintain ASHRAE TC 9.9 recommended envelopes. 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 15 Days Warning, predicting root causes such as Electronically Commutated (EC) backward-curved plug fan motor bearing seizure, Chilled water modulating control valve actuator hunting causing rack temperature thermal cycling before mechanical damage propagates.

Optruss features pre-configured kinematic signatures, vibration tolerance envelopes (ASHRAE TC 9.9 / AHRI 1360 / TIA-942), and thermal failure models for leading global manufacturers including Vertiv (Liebert), Schneider Electric (Uniflair), Stulz, Airedale. 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 Hyperscale Cloud Data Centers, Tier III / IV Enterprise Server Rooms, Telecom Central Exchanges, Edge Micro-Data Centers. Field deployments validate an average +50% MTBF MTBF extension, Data Center Power Usage Effectiveness (PUE) improved from 1.48 to 1.18 and zero server thermal throttling events., and substantial reduction in unplanned maintenance costs. Critical alerts trigger automated CMMS work orders with OEM spare parts reservation.
