This is an official Thai-language website hosted on the Singapore-registered domain sdec.sg, owned by Shanghai New Power Automotive Technology Co., Ltd. (formerly Shanghai Diesel Engine Factory, abbreviated as SDEC) — China's leading diesel engine manufacturer. It showcases the company's brand, full range of power products and service support system to industrial customers across Thailand and Southeast Asia.
The website prominently displays 7 major series of SDEC products, totaling over 300 variants, with power ranging from 50HP to 1600HP. The product portfolio covers three main categories: diesel engines, natural gas engines, and diesel generator sets. SDEC products are highly adaptable for a wide range of industrial use cases, including commercial vehicles such as buses and trucks, construction machinery, agricultural machinery, marine vessels, and mobile power stations.
With over 70 years of R&D and manufacturing experience, SDEC products have passed multiple internationally recognized authoritative quality certifications including ISO9001 and TS16949. Multiple product lines are co-developed with leading international technology partners, and their technical specifications meet mainstream global standards.
For overseas customers, SDEC offers downloadable technical documentation, remote technical consultation, and flexible training support. It has already established authorized service outlets in more than 20 countries worldwide, capable of providing localized after-sales service and spare parts supply.
Pros: As a long-established state-owned power manufacturing enterprise from China, SDEC boasts mature technology and high product reliability. Its full power coverage can meet the customized needs of different industrial customers, and it has a clear cost-performance advantage over comparable products from European and American brands. It has also built out a localized service network across Southeast Asia, so after-sales support is reliable.
Cons: The website only offers a Thai-language interface, with no Chinese or English options, which is very unfriendly for users outside Thai-speaking regions. Additionally, the official website only serves as a product showcase — it does not include public pricing, dealer search or other practical functions. Users have to contact SDEC proactively via email or phone to get cooperation information, so the interactive experience is quite inconvenient.
This website is exclusively targeted at B2B industrial customers in Southeast Asia, including commercial vehicle manufacturers, construction machinery companies, generator set integrators, agricultural machinery enterprises and similar businesses. General individual users do not need to visit this site. Currently, the website is directly accessible from networks in China.
