Automation Systems

Automation systems are the contracting service of BMS (building management system) and process automation infrastructure that monitors, controls and optimises a facility's mechanical and electrical equipment through a sensor-actuator network. The system gathers dispersed equipment — air handling units, boiler rooms, chiller groups, pumping stations, ventilation, lighting and security (cameras, access control) — into one monitoring-intervention spine, giving visibility to the operator, records to the engineer, and energy-maintenance data to management. The purpose is holding comfort and process conditions stable with less energy; automation is the plant's brain, not a luxury.

Layer Structure

• Field layer: Temperature-humidity-pressure-CO2-flow-differential sensors with motor-valve-damper-drive actuators; panel-terminal labelling and wiring (panel) standard discipline.
• Control layer: DDC/PLC controllers, serial BUS (Modbus, BACnet, LON, KNX) or IP network topology; PID loops, setpoint hierarchy, safety logic (freeze protection, high pressure lock, fire scenario).
• Management layer: SCADA central software; alarm-escalation matrix, trend logs, reporting (energy meter integration) and permission roles; remote access granted with security hardening (VPN, user audit).

Application Areas

On the HVAC side (HVAC systems) the air handling sequences (supply air temperature-fresh air-heat recovery rotation), VAV zone control and chiller group staging logic are built. In the boiler room, cascade control and air-fuel ratio optimisation (tracked with boiler periodic inspection data); in water-hydrophore (hydrophore) and compressed air (compressor) lines, pressure band control, leak metering and cascade-idle strategies come online. The energy management layer closes into a continuous improvement loop fed by thermal audits and periodic inspection findings.

Project Discipline: IO, Graphics, Testing

The backbone of an automation project is the IO list and performance specifications: every sensor-actor point is defined by type-message-range-property; graphic sequences (philosophy diagrams) are reviewed with operations. Commissioning includes point-to-point verification, loop tuning, alarm threshold trials, scenario tests (power failure, fire, freeze) and load testing. The final stage is training plus the operator handbook — automation not accepted by staff retreats within months into the comfort of "manual".

Legal Basis and Outcome

The work runs under Law No. 6331 and electrical safety rules (including bonding), energy efficiency legislation (efficient use of energy resources, metering and monitoring duties) and relevant device safety standards. For preliminary design, IO list, survey and quotation reach our engineering team via the contact page; this service sits under our Mechanical Installation Contracting heading.

Reliability and Safety Logic

Automation's first duty is safety, not comfort: freeze stats and high-pressure locks, exhaust-fan feedback and generator supply transfer scenarios (coordinated with the generator infrastructure) are mandatory layers of every project. To prevent alarm fatigue, delays and priority classes are applied to thresholds; critical alarms escalate to the operator on dual SMS-SCADA channels. The management network is segmented from the data infrastructure; controller firmware updates and configuration backups enter the maintenance plan. Record integrity (trend-log archive) is the facility's witness in any fault or audit investigation.
