Today’s project involved the removal of an outdated BMS panel and the installation of a new pre-manufactured panel, designed and built in-house. The new panel integrates seamlessly into the building management system (BMS), offering enhanced visibility and control over essential systems, which was absent in the previous setup. The upgrade ensures better monitoring and management from both the hangar and the main office, significantly improving operational efficiency.
Removal of the Old BMS Panel
The first stage of the project involved the safe and systematic removal of the old panel:
- Safe Isolation:
- The power supply to the old panel was safely isolated to ensure the safety of the team during disconnection.
- Circuit Disconnection and Labeling:
- All circuits connected to the old panel were carefully disconnected.
- Each circuit was clearly labeled to ensure easy identification during the transition to the new panel.
- The disconnected circuits were pulled into a safe and accessible location, ready for termination into the new panel.
- Dismantling the Old Panel:
- The old panel was unbolted from the unistrut framing.
- Once detached, the panel was removed from the site for proper disposal or recycling.
Installation of the New Panel
The newly installed panel, built in-house, now provides comprehensive control and monitoring capabilities for various systems.
Systems Managed by the Panel
The new panel manages the following systems:
- Kitchen Supply AHU Extract: Ensures efficient air handling and ventilation in the kitchen area.
- Toilet Extract: Provides proper ventilation for hygiene and comfort.
- Changing Room Extract: Facilitates effective air extraction for comfort and airflow.
Installed Sensors
- Supply Sensor: Controls the heater battery temperature with a high-limit thermostat for added safety.
- AHU Extract Temperature Sensor: Provides a temperature reference for the air handling unit.
- Restaurant Temperature Sensors (x2): Offers precise readings for improved temperature management in the restaurant area.
Key Features of the New Panel
The new panel includes advanced components for enhanced functionality:
- Thyristor: Controlled by set points and a time schedule for energy-efficient operation.
- Manual Motor Starters: Ensure safe and effective control of fans.
- 3-Phase Contactor Relays: Manage high-power devices reliably.
- Change-Over Timers: Enable seamless switching between high and low-speed fan modes.
- Overload Trip Devices: Monitored for safety and system protection.
- MCBs: Provide circuit protection and stability.
- Distech Controller: Offers integration with BMS software for streamlined management.
- Transformer (24V to 240V): Powers panel components efficiently.
- Moxa Managed Switch: A 2-port fibre and 6-port Ethernet (100mb) switch for robust communication.
- 230V Single Socket: Provides added convenience.
- Cooling Fan with Thermostat: Prevents overheating and ensures consistent performance.
- Mini Contacts (2-Pole, Single-Phase): Enable precise switching.
- 3-Phase and Neutral 125A Main Isolator: Ensures safe and reliable power management.
Improvements Over the Old Panel
The old panel lacked integration with the BMS, limiting its functionality and visibility. The new panel bridges this gap, providing advanced control and monitoring capabilities. With visibility accessible from both the hangar and the main office, it enables improved operational efficiency and responsiveness.
Outcome
The project was completed successfully, with the outdated panel safely removed and replaced by a modern, pre-manufactured panel. The new setup streamlines operations, improves environmental control, and offers scalability for future requirements. The combination of careful planning, safe isolation, and expert installation ensures that the upgraded system meets the highest standards of functionality and safety.
Today’s work demonstrates the value of modernising critical infrastructure and integrating advanced technologies to meet the demands of contemporary operations.
