In the fast-growing fields of cold-chain logistics and smart agriculture, cold storage facilities have become the true “lifeline” of fresh produce, food, and pharmaceuticals. Yet, many cold-storage operators still struggle with critical concerns:
• Unstable equipment? A single unexpected failure can cause millions in losses.
• Temperature fluctuations? Even brief deviations may spoil fruit and vegetables, or compromise the efficacy of medicines.
• Opaque operations? Traditional systems lack transparent records, making issues difficult to trace.
• Harsh environments? Extreme heat, humidity, or wide day-night temperature swings often trigger electrical failures.
These challenges are no different in Russia’s smart agriculture projects. The key question is: how can cold storage facilities remain stable, intelligent, and fully controllable?
Envintel’s intelligent control system provides a reliable answer—combining superior product quality with advanced design to safeguard critical operations.
01 – Stable Core: Siemens S7-1500 PLC
Cold-storage operations demand near-absolute stability. Even a few minutes of control failure can lead to devastating losses. For this reason, the choice of PLC at the heart of the control system is critical. Envintel systems integrate the Siemens S7-1500 PLC, recognized across the industry as an “industrial-grade heart” thanks to its high performance and redundancy.
• Dual-CPU hardware redundancy: The main CPU handles real-time operations, while the backup CPU stays fully synchronized and ready. If the main CPU fails due to overheating, short-circuit, or external shocks, the backup takes over seamlessly within milliseconds, ensuring uninterrupted temperature control.
• Redundant software logic: Advanced algorithms constantly monitor both CPUs. At the first sign of risk, the system triggers instant switching to keep all commands running.
• High-speed communication: S7-1500 supports powerful industrial networking, coordinating refrigeration, ventilation, lighting, and other subsystems to achieve system-level integration.
In one Russian cold-storage project, a lightning strike damaged the main CPU. Thanks to redundancy, the backup CPU immediately took control, maintaining stable temperature and preventing major product losses. This case clearly demonstrates both the reliability of the Siemens S7-1500 and the robust protection built into Envintel’s solution.
02 – Predictive Intelligence: SCADA + AI Big Data
Equipment rarely fails without warning—it usually deteriorates over time. Traditional manual inspections often overlook early signals until major damage has already occurred. Envintel integrates SCADA visualization with AI-driven big data analytics, transforming maintenance from passive response to active prevention.
• SCADA visualization: Like a digital map, it provides real-time graphical displays of system conditions—temperature, voltage, current, and pressure—helping operators manage the system with clarity.
• AI anomaly detection: By learning from historical and real-time data, AI establishes a “normal operation model.” Even subtle deviations are detected instantly, with forecasts of potential fault points and timing.
• Proven pre-warning: In one food-storage facility, AI detected abnormal compressor patterns. Inspection confirmed severe wear in a critical part, which would likely have caused a shutdown. Timely replacement prevented millions in losses.
With this system, operators no longer “repair after failure,” but instead act before problems occur. Statistics show that Envintel’s predictive intelligence has reduced sudden equipment failures by over 60%, saving both costs and downtime.
03 – Transparent Operations: Audit Trail + Mobile Management
Another pain point in the cold-chain industry is lack of accountability. Did staff inspect on time? Was a temperature adjustment authorized? Who modified the parameters? Without transparent logs, management is reactive at best.
Envintel systems solve this through a built-in audit trail:
• Complete traceability: Every start-up, shutdown, parameter change, and maintenance activity is recorded with precision, building a complete operational archive.
• Regulatory compliance: In pharmaceutical cold storage, audit data provides trusted records for quality assurance and compliance.
• Fast fault tracing: When anomalies occur, managers can quickly trace back to the exact action that caused them, reducing troubleshooting time.
More importantly, Envintel offers mobile remote management:
• Managers can check cold-storage status anytime, anywhere.
• During peak logistics periods or multi-site operations, they no longer need to be physically present.
• The system sends instant alerts directly to mobile devices, ensuring rapid decision-making and response.
In Russia’s agricultural projects, customers reported that mobile management reduced unnecessary site visits during peak harvest season, boosting efficiency by nearly 100%.
04 – Long-Term Protection: Rittal Enclosure + Cooling System
Environmental stress is a hidden but serious threat to reliability. Envintel’s systems use original Rittal enclosures, known for exceptional anti-vibration and protective performance, providing long-term security for internal components.
Additionally, a dedicated cooling system ensures stable working conditions for low-voltage devices. Whether in hot and humid summers or regions with sharp day-night temperature swings, the system maintains optimal cabinet conditions, preventing frequent breakdowns and ensuring continuous operation.
