From survey to lifetime support
Eight services covering every phase of an environmental monitoring system — engineered, delivered and supported by AESST.
Engineering, Procurement & Site Survey
Multidiscipline engineering — instrumentation, electrical, mechanical, automation and environmental — from feasibility and basic engineering through detailed design, P&IDs, GA drawings, cable schedules and BOQs.
- CPCB / US EPA siting study & stack assessment
- Basic, detailed & system engineering
- AERMOD / CALPUFF dispersion modelling
- Panel, shelter & sample-conditioning design
Turnkey EPC — Installation & Commissioning
Single-point EPC delivery for AQMS, CEMS, process analyzers and met systems — mechanical erection, electrical & signal cabling, loop checks, FAT/SAT, cold and hot commissioning and regulator hand-over.
- Mechanical, electrical & I&C erection
- FAT / SAT and loop checking
- Cold + hot commissioning
- CPCB CARE Air / SPCB uplink integration
Calibration & Validation
ISO 17025-aligned calibration for AQMS, CEMS, process and water analyzers using NIST / NPL traceable reference gases and standards, plus QAL2 / RATA performance audits and system validation.
- Multi-point zero, span & linearity audits
- NIST / NPL / NABL traceable standards
- QAL2, RATA & performance audits
- Signed compliance & calibration certificates
Preventive & Health-Check Maintenance
Scheduled PM, system health audits and preventive interventions that keep analyzers, sample handling and DAS compliant between regulatory audits — consumables, line audits, firmware and full PM reporting.
- Quarterly / half-yearly PM cycles
- Sample-line, probe & filter audits
- Firmware, driver & software updates
- Detailed PM and health-check reports
AMC, CMC & O&M Contracts
Annual Maintenance (AMC — labour & visits), Comprehensive Maintenance (CMC — labour, spares & consumables) and full Operation & Maintenance (O&M — resident engineers operating the system) tiers, each SLA-backed with uptime guarantees.
- AMC: scheduled visits + 24×7 helpdesk
- CMC: labour, spares & consumables included
- O&M: resident engineers, full plant ownership
- Shutdown, start-up & emergency response
Digital Services & Remote Monitoring
Industrial dashboards, SCADA / PLC integration, IIoT, data historians, AI analytics and predictive maintenance — built on a hardened DAS that streams to your historian and to CPCB / SPCB regulators.
- Cloud dashboards & alarm management
- Historian, OPC UA, MQTT & SCADA integration
- AI analytics & predictive maintenance
- Validated reports & mobile access
Technical Helpdesk & Troubleshooting
24×7 senior-engineer helpdesk for remote diagnostics, root-cause analysis, vendor escalation and on-site rapid response — backed by spare-parts stocking and operator / maintenance training.
- 24×7 remote diagnostics
- On-site rapid response
- RCA documentation & corrective actions
- Operator, calibration & compliance training
Modernization, Retrofit & Lifecycle
Migrate legacy AQMS / CEMS / process systems to current standards — analyzer retrofits, DAS migration, protocol & cyber hardening, spare-parts lifecycle support and digital transformation programs.
- Analyzer & sensor retrofits
- DAS, protocol & cybersecurity upgrades
- Legacy-system migration & digital twin
- Lifecycle spares & asset management
