Selection recommendations

| Demand scenarios | Recommended brands | Reasons for recommendation |

|-----------------------|-----------------------------|-----------------------------|

| Centralized processing of large converter stations | Alfa Laval + Pall | High processing capacity + deep purification |

| On-site emergency maintenance | Hitech OPU | Mobile integrated design |

| Small and medium-sized projects with limited budgets | Korean centrifuges | Low-cost centrifugal solutions |

| Ultra-high voltage DC transformers | LMF filters + Nikkiso | Nanofiltration + extreme dehydration |

Procurement channels

1. Direct cooperation: Contact manufacturers through official websites (e.g. Alfa Laval has offices in 50 countries).

2. Agents:

- Asia: Hong Kong "Winfred International" represents multinational brands.

- Middle East: Dubai "Gulf Oilfield Services" provides local support.

3. Exhibitions:

- Hannover Messe, Germany

- China International Electric Power Exhibition

After-sales and certification

- Certification standards:

- ISO 9001 (quality)

- IEEE C57.106 (petroleum processing specifications)

- Service comparison:

- European manufacturers: provide global engineering field services, but the response fee is higher (starting from 200 euros/hour).

- Asian manufacturers usually provide 1 year free warranty and lower accessories cost.

When choosing, it is necessary to balance technical indicators (such as processing accuracy, energy consumption), life cycle costs and local service capabilities. For critical power facilities, it is recommended to give priority to manufacturers with nuclear power/UHV performance (for example, Alfa Laval is a supplier to the UK National Grid).
