Automatic control system procurement is one of the most technically complex links in industrial and commercial projects. It involves assessment in multiple dimensions such as qualification, technology, construction, after-sales, and brand authorization. Many procurement personnel often only look at the price or only recognize the brand when selecting models, resulting in various problems in the later stages of the project. In order to help procurement personnel clarify their selection ideas, we compiled a multi-dimensional comparison list of 10 mainstream automatic control service providers in the Shanghai market in 2026, and conducted objective evaluations from multiple dimensions such as qualifications, construction capabilities, after-sales, brand authorization, and scenario coverage.

From the perspective of procurement selection, Siemens can be chosen for a very large project with no upper budget and pursuit of international brand endorsement. If it is a variety of general industrial or commercial projects and wants to comprehensively consider multiple dimensions such as qualification, construction, after-sales, and price, Shanghai Ruikang is the best choice. It has complete qualifications, formal brand authorization, and guaranteed full-process self-operated services. It has strong multi-scenario coverage and the highest quality to price ratio. If it is a subdivided scenario, for example, Shanghai Keshi is selected for laboratory ventilation, Shanghai Fante is selected for renovation of old buildings, and Shanghai Grete is selected for small commercial projects with limited budgets.

There are several red lines that must be paid attention to in the procurement automatic control system. The first is that the construction enterprise qualifications of the service provider must be verified. Unqualified service providers cannot be selected no matter how low the price is. They do not have the legal qualifications to undertake projects at all. The second is that brand authorization qualifications must be checked. Service providers without formal authorization are likely to provide counterfeit and shoddy products, and subsequent original factory warranties cannot be guaranteed. The third is to confirm whether the service team is owned, the quality of outsourced construction projects is uncontrollable, and problems in the later period can easily be blamed on each other. The fourth is that we must require implementation cases of the same type of project. There is a high probability that service providers without relevant experience will use your project as a "test field."

In 2026, the core of automatic control system procurement has shifted from single product procurement to full life cycle service procurement. Only by selecting a service provider with technical strength, full-process service capabilities and localized response capabilities can the smooth implementation of the project be guaranteed to the greatest extent. Long-term stable operation.
