"Does it work right after installation, or do we need to assemble it on site?" — This question appears in inquiries far more often than most people imagine. Many buyers have previously experienced split-type equipment, which requires coordinating installation teams, cranes, pipeline connections, and system commissioning after arrival at the port, often dragging on for one to two months. So when they purchase again, the first question is: Is this thing integrated?
To be honest: Yes. And this is not a vague claim like "easy to install" — it is factory pre-assembly. Before leaving the factory, Huayan's CNG Integrated Skid Station (HYZ-1000/25-CNG) has all the following core components assembled and fixed inside a standard 40-foot container frame (12192 × 2438 × 1400mm). The appearance can be chosen as container-type, open-type, or split-type, but the internal integration logic is completely identical.
Factory Pre-assembly List of Key Components:
Subsystem | Factory Status | Function Description |
Unloading Column | Installed | Connects to CNG tube trailer, receives 0.3–20 MPa inlet gas |
Gas Filter | Installed | Removes impurities, protects downstream components |
Hydraulic Compressor | Installed | Hydraulic reciprocating double-acting type, boosts low-pressure gas to 25 MPa |
Cooling System | Installed | Air cooling + water circulation, maintains stable operating temperature |
Cylinder Storage Group | Installed | High-pressure gas storage, balances flow between compression and dispensing |
CNG Dispenser | Installed | Dispenses directly to vehicles, integrates metering and payment |
PLC Control Cabinet | Installed | Fully automatic logic control, supports remote monitoring and unattended operation |
PRMS (Pressure Regulating & Metering System) | Installed | Pressure regulation and metering, ensures stable outlet pressure |
Generator Set | Installed (Optional) | Gas/diesel optional, independent power supply, suitable for sites without grid |
This list makes it very clear: One unit covers the entire process of unloading, compression, cooling, storage, dispensing, control, and pressure regulation. There is no situation where several modules need to be assembled on site with a crane.
Why is this so important? Because integration is not just about "saving installation time." After split-type equipment arrives at the port, the modules need re-piping and leak testing on site — these are the steps most prone to accidents in any project. Mismatched interfaces, seals shifted during transport, piping installation errors exceeding limits... each problem means rework and waiting. However, Huayan's skid stations complete all pipeline assembly and leak testing before leaving the factory, along with pressure verification. What needs to be done on site is simply connecting the external power supply and the inlet gas pipeline. This means that after the equipment arrives at its destination, the commissioning cycle can be compressed to a minimum. The PLC fully automatic control system supports completely unattended operation, eliminating the need to station dedicated operators. If there is network access, remote monitoring can be activated to view the operational status in real-time from the head office or maintenance center.
Now to answer the second question — how long for delivery?
Item | Timeframe |
Standard Models (HYZ-1000/25-CNG etc.) | Shipment within 30 days after payment |
Custom Models (Flow/Medium/Frame customization) | Shipment within 40 days after payment |
Warranty Period | 12 months of operation or 18 months from shipment (whichever comes first) |
Three flow rates cover the needs of most projects: 1000 Nm³/h, 1200 Nm³/h, and 2500 Nm³/h, matched according to actual gas consumption requirements. The working pressure is uniformly 25 MPa (250 bar), and the inlet pressure adaptation range is wide, from 0.3 to 20 MPa — the intent of this parameter design is to ensure the skid station can stably connect to tube trailers from different sources, regardless of the gas source pressure. Transportation does not require special arrangements either. As a standard 40-foot container frame equipment, it supports three main shipping methods: container ship, bulk carrier, and roll-on/roll-off (RO-RO), with a clear customs clearance process. The total weight is approximately 37 tons, well within the capability of conventional logistics for lifting and transshipment.
Let me add one point buyers often overlook: Media switching. Besides CNG, this Huayan product series is explicitly compatible with compressed hydrogen (H₂), nitrogen (N₂), and helium (He). If there is a need for hydrogen filling, specify it when ordering, and Huayan will customize the sealing materials and pipeline cleaning standards for the target medium during the factory stage.
To put it bluntly: What determines the speed of commissioning? It's not how many days the on-site debugging takes, but how much preparation was done at the factory. Integrated delivery, factory pressure verification, and PLC fully automatic operation — these three elements combined are the true standard for whether a skid station can be "commissioned upon arrival." Huayan's products are designed exactly according to this logic.
