Every building system, in one view.
We design, supply, program and commission building management systems that control HVAC, chillers, lighting and building services from one platform, with energy monitoring, alarms and remote 24/7 access.
A building management system (BMS) is the control network that connects a building's mechanical and electrical services, such as chillers, air handling units, pumps and lighting, so they can be scheduled, monitored, alarmed and optimised from one place.
Why it matters
Schedules, setpoints and energy monitoring show where a building wastes energy.
Alarms and diagnostics point the facility team to the fault before occupants notice.
Equipment from different manufacturers and sites can be supervised from one system.
What our BMS controls
Chillers and plant rooms
Chiller sequencing, pumps, cooling towers and plant-room monitoring.
Air handling units
Supply air temperature, fans, dampers, filters and fresh-air control.
FCUs and VAV boxes
Room temperature, schedules and occupancy for every zone.
Lighting
Time schedules, occupancy and daylight control of lighting circuits.
Energy metering
Electricity, chilled-water and water meters with consumption reports.
Critical rooms
Room pressure monitors such as Setra FLEX connected over BACnet.
System architecture
| Level | What it does |
|---|---|
| Field level | Sensors, actuators and valves on the equipment. |
| Automation level | Controllers that run the control logic for each system. |
| Management level | Head-end software for graphics, alarms, trends and reports. |

FAQ
What is a BMS?
A building management system (BMS), also called a building automation system (BAS), is the control network that connects a building's HVAC, chillers, pumps, lighting and meters so they can be scheduled, monitored, alarmed and optimised from one workstation.
Who installs BMS systems in Saudi Arabia?
Electrex Arabia is a BMS contractor based in Riyadh. We design the control scheme, supply and build the control panels, install field devices and cabling, program the controllers and graphics, integrate third-party systems over BACnet, and commission and maintain the system.
What is BACnet?
BACnet is an open communication protocol for building automation. It lets equipment from different manufacturers share data and alarms with one BMS.
Can you connect equipment from other manufacturers?
Yes, where the equipment offers a supported interface such as BACnet.
Can the BMS be monitored remotely?
Yes. Remote 24/7 monitoring is part of the service where the client's network policy allows it.
Can you upgrade or extend an existing BMS?
Yes. We survey the existing controllers and network, then extend or migrate the system in stages so the building keeps running during the work.
Can Setra room pressure monitors connect to the BMS?
Yes. Setra FLEX connects over BACnet/IP or BACnet MS/TP, so room pressure, temperature, humidity and alarms appear on the BMS graphics and trend logs.
