Process automation, SCADA, electrical engineering and IoT — the intelligent layer that connects and controls your infrastructure.

ProStream Group designs, builds and implements automation, electrical and control systems for water treatment, energy and industrial infrastructure. From SCADA programming and electrical panel production to IoT-enabled remote monitoring, we deliver the control layer that makes plants run efficiently, safely and with full visibility. Our systems are deployed across wastewater treatment plants, drinking water facilities, pumping stations, power generation sites and industrial process environments.

How do we deliver?

We provide end-to-end automation and electrical engineering — from system design and panel production through programming, installation, commissioning and ongoing remote support.

• SCADA system design and implementation — Design, setup and commissioning of SCADA systems for automatic control and management of industrial processes; development of application software for programmable controllers; engineering solutions for optimal and efficient operation of automatic systems. Platform: SIMATIC WinCC Runtime Professional, TIA Portal V13 – SIMATIC Step7 Professional and SIMATIC WinCC Professional.
• Automation of technological processes — Selection, delivery and commissioning of control-measuring instruments and automation tools; engineering solutions for process optimisation across water, energy and industrial sectors.
• Design and assembly of electrical panels — Complete design, production, installation and maintenance of medium voltage and low voltage switchboards and control panels. Production includes: relay boards, automation boards, control panels, clamp panels, distributive panels, motor control centre, lighting panels, SIVACON control panels and SIM-CODE panels.
• Electrical construction — Construction, repair and maintenance of electrical networks and installations (medium and low voltage): power lines and cable lines, transformer stations and distribution systems, industrial and domestic power and lighting installations, repair and modernisation of distribution systems, internal installations, start-up works.
• IoT services and solutions — Network of physical objects with built-in electronics, software, sensors and network connectivity enabling real-time data collection, remote control via existing network infrastructure, and direct integration between physical infrastructure and computer-based monitoring systems. IoT connects to SCADA systems and shares sensor data via internet/cloud to any device.
• Remote monitoring — Implementation of monitoring systems for technological processes; measurement, monitoring and control of equipment parameters; alarms and preventive actions; real-time monitoring and data recording; asset management including location tracking. Flexible platform for distributing data by category, positioning objects on maps, and generating reports accessible from anywhere at any time.

What do we deliver?

• Water and wastewater infrastructure: SCADA systems for wastewater treatment plants, drinking water treatment plants and pumping stations — visualisation of treatment processes, automated control of mechanical and biological treatment stages, alarm management, trend analysis. Electrical panel boards with automation and SCADA connectivity for pump station reconstruction projects. Control panels for filtering equipment in DWTP facilities.
• Energy sector: SCADA implementation and control panel delivery for nuclear power plant water pretreatment facilities (including SIVACON control panels and automation panels). Electrical installations and control systems for hydro power plant reconstruction. Automation and electrical works for thermal power and district heating facilities.
• Industrial processes: Automation, management and control of technological processes across industrial sectors including food production, mining, recycling, machine manufacturing, automotive, and construction. Process optimisation through integrated SCADA and control systems.
• Transport infrastructure: Remote monitoring of railway infrastructure — partnership with Strukton (Netherlands) for monitoring and management of train switches and railway assets in Bulgaria. Online platform with real-time asset information, monitoring, analysis, reporting and preventive action for failures and accidents. Connected transport systems for tracking vehicle location, speed, passenger counts and optimising operations.
• Cross-sector IoT applications: Remote monitoring of infrastructure objects across water, hydrotechnical facilities, renewable energy, industry, transport, building installations and agriculture. Real-time machine tracking for preventive maintenance systems.
