The Beginning of Cummins DKSH (Thailand) Co., Ltd.

In Thailand, Cummins engines and products were first distributed by Diethelm & Co., Ltd., as the importer and distributor in 1964. Later, Cummins Inc. decided to invest in a joint venture with Diethelm & Co., Ltd., leveraging both parties’ strengths, including expertise in diesel engines and alternative energy from Cummins and DKSH’s market expansion leadership. This partnership was renamed Cummins DKSH (Thailand) Co., Ltd. in 2009, marking over 60 years of continuous development to offer our comprehensive expertise and services to support our customers, partners, and business allies in the best possible way.

The primary goal of Cummins DKSH (Thailand) Co., Ltd. is to distribute engines, generators, parts, and high-standard repair services to businesses and industries requiring power sources, especially diesel engines in Thailand. We believe our products will support your business growth, not just in financial numbers, innovation, and quality, but we are committed to achieving these results from a foundation of environmental safety, workplace safety, and safe working practices for our employees, customers, and business partners.

4 Reasons Why The Entrepreneurs Choose Cummins Engines

Today, Cummins engines and after-sales services are trusted and relied upon for their quality by entrepreneurs in Thailand, for the following four reasons

1. Cummins can design engines and specify them according to made to order applications

Businesses may have similar engine requirements, but specific needs, job site limitations, and organizational environmental policies make each engine unique. We can design and manufacture to meet these specific needs, known as Made To Order production. This ensures engines are perfectly sized and perform according to the specific applications of each business, including adding specific functions like exhaust treatment systems to meet environmental standards (such as EURO 3, 4, 5, etc.). Importantly, designs consider user safety to mitigate potential risks.

2. High-performance Cummins engines deliver the required load

Every Cummins product is designed, invented, and produced to international standards by knowledgeable and experienced engineers, undergoing rigorous testing to ensure that entrepreneurs and our customers can use the engines to their full potential, achieving the necessary power without being underpowered for operations or overusing fuel. High performance meets the demands of the activities performed.

3. Durable, continuous, long-term operation, thus cost-effective

Given the challenging conditions and environments where Cummins engines operate vigorously and against time, our engines are expected to be a continuous source of power even in challenging conditions, described as robust, resilient, and durable.

"Expert Engine design + High-teach manufacturing = Durability and Valued for Money"

With expert manufacturing combined with appropriate engine design for the job characteristics, we can support the growth of every business, reduce production losses, minimize work delays, and ensure long-term use*. This represents the value for every baht spent.

*Provided that it is used and maintained properly
