For customers with medium gas demand, we can supply gas through high-pressure tube bundle trucks. Bulk hydrogen is usually supplied by high-pressure gas long-tube trailers. When the gas is delivered, the pressurized gas can be transferred directly to permanent storage tanks, or the long-tube trailer on site can be used as a storage device. The high-pressure gas long-tube trailer can be equipped with a telemetry system for real-time remote monitoring to ensure gas supply at all times.
