02Power monitoring

Lubrication system stability protection

Power system "blood" monitoringLow lubrication oil pressure protectionReal-time tracking of drivetrain lubrication status. When oil pressure drops below safety thresholds, the system cuts power to prevent bearing wear or seizure caused by lubrication failure, safeguarding equipment mechanical life.

Gas source stability interventionLow intake pressure protectionIntelligently detects upstream fluctuations. Active intervention at low intake pressure prevents instability, vibration, or damage from vacuum or starvation, ensuring continuous, balanced suction.

System-level explosion-proof safety controlSecondary stage discharge pressure protection

High-pressure safety line for final discharge. When pressure hits the limit, secondary protection triggers via electronic monitoring and active intervention to prevent systemic overpressure and safeguard pipeline assets.

Defining SafetyThrough Extreme Validation

Safety is not a promise; it is a proven result. Before delivery, every unit must undergo tens of thousands of fatigue cycle tests and simulated operational drills that push beyond design limits.

Maintaining 100% reliability in extreme environments is our ultimate commitment to your asset security and production continuity.

No matter where you are located, MINNUO's full range of products supports flexible, containerized skid-mounted deployment. Complemented by our global technical support and rapid response network, we empower your energy transition through the excellence of Intelligent Manufacturing in China.

Hermetic SealingUtilizes VCI technology and vacuum sealing as "invisible armor" to block salt spray, moisture, and corrosion. This ensures core precision components maintain factory-grade cleanliness and luster during long-term maritime transit or storage.

Multi-Point AnchoringMechanically modeled by center of gravity, high-strength steel bases and flexible straps provide multi-point support. This logic offsets transit shocks and eliminates relative displacement within the container.

Global DeliveryPackaging is fully compatible with 20GP/40HQ standard containers, optimizing loading efficiency and reducing handling risks. We offer traceable, standardized delivery for projects worldwide.

On the map of Spain's green transition, this Minnuo-enabled hydrogen station stands out as a high-performer, capable of refueling 4.8 tons daily to power 800 fuel cell vehicles. With word-leading scale and expertise, it serves as a premier national hydrogen demonstration landmark for both Spain and the broader European region.

Full-Process Safety RedundancyIntegrated with leak detection, auto-sprinkling, pressure relief, and static grounding. This multi-layered safety loop ensures hydrogen remains under total control during compression, storage, and refueling.

Deep Cooling TechnologyIntegrated high-efficiency pre-cooling prevents gas overheating during refueling. By delivering hydrogen at a stable low temperature, the system optimizes filling speed while ensuring the absolute safety of the on-board storage tanks.

As North China's leading hydrogen refueling hub, the Tianjin Xinheng Energy project serves as a core nexus in Tianjin Port Free Trade Zone's hydrogen energy industrial layout, playing a key role in regional hydrogen supply security. The project not only successfully provided stable, high-purity hydrogen backup for fuel cell vehicles during the 2022 Beijing Winter Olympics, but also became Tianjin's first commercially operational hydrogen refueling station with daily hydrogen supply capacity reaching 20 tons. Its smooth commissioning marks the entry of North China's hydrogen infrastructure into a new phase of scaled commercialization.

Modular & Agile Delivery ArchitectureBased on a "LEGO-style" design philosophy, core units—including refrigeration, fueling, and control systems—are integrated within standard explosion-proof enclosures. This solution supports rapid site expansion and relocation, reducing onsite construction workload by over 60% and significantly shortening the overall project lead time.

High-Purity Compression ProcessUtilizing hydraulic-driven diaphragm compressors, this process achieves physical isolation between the hydrogen and the driving medium. By eliminating lubricant contamination at the source, it ensures that the dispensed hydrogen purity remains consistently stable at 99.97% or higher.
