Key Considerations for Selecting Skid-Mounted Refueling Units
I. First, Determine Three Core Parameters
1.Capacity Selection (m³)
(1)5/10 m³: Small vehicle fleets, temporary construction sites, agricultural machinery, small-scale logistics operations
(2)20/30 m³: Medium-sized vehicle fleets, concrete mixing plants, mining sites, ports
(3)50 m³: Large-scale logistics parks, extensive mining areas, airport ground support operations, long-term fixed refueling stations
(4)Principle: Tank capacity should be selected based on the Daily Refueling Volume multiplied by a Reserve Supply Duration of 2 to 3 days.
2.Media Types
(1)Diesel-Skid: Most common;relatively lower explosion-proof requirements.
(2)Gasoline Skid: Must feature barrier-type explosion protection + vapor recovery + enhanced safety measures.
(3)Jet Fuel / Ethanol Gasoline: Requires specialized sealing, corrosion resistance, and specific explosion-proof ratings.
3.Explosion-Proof Ratings & Safety Standards
(1)Mandatory Features:Barrier-type explosion-proof packing (HAN) + Double-walled tank + Leak detection system.
(2)Explosion-Proof Rating:Ex d ⅡB T4 or higher.
Compliance Requirements:Compliant with GB 50156, AQ3002, and other relevant standards.
II. Functional Configuration Options
1. Fuel Dispensing Unit
(1)Single-nozzle / Dual-nozzle / Quad-nozzle configurations.
(2)Flow Rate:45–80 L/min (High-flow rates recommended for heavy-duty trucks).
(3)Metering Accuracy:Within ±0.3%.
2. Management System
(1)IC card management, access control, quantitative fueling.
(2)Remote monitoring, real-time liquid level display, report generation.
(3)Anti-theft protection, anti-fraud measures, fuel consumption statistics.
3. Safety & Security System (Mandatory)
(1)Emergency shut-off valves.
(2)High-temperature / Over-pressure / Leakage alarms.
(3)Combustible gas detection.
(5)Automatic fire suppression system (Optional).
4. Environmental Protection Features
(1)Vapor recovery system (Mandatory for gasoline skids).
(2)Impermeable containment pit / Leak-proof bund (dike).
(3)Corrosion-resistant, weather-proof exterior casing.
III. Structure & Installation Formats
(1)Integrated Skid:Tank, dispensing unit, and safety systems are integrated into a single unit; small footprint, rapid installation.
(2)Split-System:Tank farm and dispensing unit are separated; suitable for large sites or industrial parks with stringent requirements.
(3)Mobile Unit:Features a base frame for crane lifting and relocation; suitable for construction sites or field operations.
IV. Materials & Environmental Adaptability
(1)Tank Body:Q345R pressure vessel steel plate; features both internal and external anti-corrosion treatment.
(2)Extreme Cold Regions: Heat tracing, thermal insulation, low-temperature-rated valves.
(3)Coastal / Salt-Spray Regions:Stainless steel piping + Enhanced anti-corrosion treatment.
V. Simplified Selection Guide
(1)Small Fleet / Agricultural Machinery ：| 5–10 m³ | Single-nozzle, Diesel, Basic Safety Features
(2)Medium-sized Construction Site / Concrete Batching Plant ：20–30 m³ ,Dual-nozzle,IC Card System Card Access & Leak Detection
(3)Large-scale Logistics / Mining： 30–50 m³, Four Dispensers, Vapor Recovery, Remote Monitoring
(4)Ports / Airports： 30–50 m³ ,Enhanced Explosion Protection, Corrosion Resistance, High Security
