Empowering Industrial Operations, Smart Utilities, and Mine Digitization Across Central Africa with High-Performance, Rugged, and Secure Edge Intelligence.
High-reliability systems optimized for harsh environments, featuring extended operating temperatures and resilient cellular communications.
The Democratic Republic of the Congo (DR Congo) holds a strategic, world-leading position in green energy resources and key battery minerals. The Katanga and Lualaba Copperbelts contain the highest-grade deposits of copper and cobalt globally. Extracting, processing, and transporting these resources efficiently requires state-of-the-art automation systems. However, industrial operations in remote areas face structural challenges: limited power grid stability, extreme thermal variations, high dust concentration, and highly constrained, high-latency satellite or cellular WAN backhauls.
This is where Edge Computing Gateways become indispensable. Rather than streaming high-frequency raw data streams over expensive, unstable VSAT or 4G links to overseas cloud infrastructure, Fray Tech's intelligent gateways process, aggregate, and analyze data locally at the source of production. By filtering out noise and sending only critical event state changes or aggregated alerts to central SCADA networks, our systems optimize bandwidth consumption by up to 90%, ensure offline continuity (store-and-forward), and guarantee real-time machinery control.
Addressing the complex engineering challenges of mining, smart grids, and heavy-duty infrastructure.
Integrating subterranean HVAC systems, methane detectors, and water pumps. Using LoRa gateways and Modbus controllers to relay environmental parameters to surface SCADA hosts without expensive wiring over extreme distances.
Monitoring rural hybrid-solar installations and high-voltage transmission lines from Inga Dam. RTU-enabled Modbus converters digitize power parameters (voltage surges, current, battery SOC) and transmit reports over 4G networks.
Continuous monitoring of fuel reserves, engine temperatures, and vibration profiles on mine trucks. Linux-based gateways perform localized predictive modeling to forecast equipment failures, saving millions in downtime.

We recognize that deploying industrial computing hardware in Sub-Saharan African locations demands specialized architectural adaptations. Fluctuating voltage networks, heavy inductive loads from high-capacity induction mining equipment, and micro-grid switching configurations lead to severe power transients. Fray Tech solves these realities by engineering a robust 9V to 36V wide-voltage input range directly into our power supply unit (PSU) boards, accompanied by integrated overcurrent and surge protection.
Furthermore, Fray Tech provides direct technical assistance to systems integrators in DR Congo. We support local projects with detailed hardware calibration, firmware tailoring for specific Modbus profiles, and optimization of communication scripts on Ubuntu-based nodes. We help optimize parameters such as watchdog auto-reboots, transmission frequency limits, and encrypted security policies to safeguard telemetry from interception or interference.
