Your Success is Our Priority
At ASKO, we’re dedicated to advancing the steam turbine industry and supporting local communities across Thailand. We’re motivated by the positive impact we make, celebrating every step forward in our customers’ industrial operations.


Company History
ASKO has a long-standing reputation for industrial engineering excellence. Our journey began over four decades ago when our founder Mr. Amnuay Siahmeng ventured to support the sugar, paper, and power generation industries in Thailand and Southeast Asia through steam turbine engineering services. With his in-depth industry knowledge, OEM training, and overseas experience, he officially founded ASKO Equipment Company Limited in 1990. Today, we remain a family-owned and operated business that proudly employs over 100 individuals in Ratchaburi, Thailand.

Safety and Quality
Our engineering team is at the forefront of safety and quality processes for our industry. ASKO’s commitment to quality is demonstrated through our quality management system, which is certified under the United Kingdom Accreditation Service (UKAS) ISO 9001:2015 standard. This certification reflects our ability to consistently provide reliable products and services to our clients. Additionally, our workshop tools are always certified and inspected according to the original equipment manufacturer’s guidelines.

Facilities
The ASKO workshop is a one-stop shop for industrial equipment manufacturing, engineering design, and service maintenance. As a turn-key services provider, we’re able to cater to diverse engineering needs from concept to completion, ensuring seamless integration into your project. At our workshop, our team uses modern machining centers, CNC machines (3-axis, 4-axis, 5-axis), lathes, electric wire cuts, and other advanced tools to ensure precision and efficiency throughout all manufacturing and servicing.
Our workshop is entering an exciting new chapter with major renovations taking place from late 2024 into 2025. Throughout this period we remain fully operational for off-season support needs, continuing to provide the same high-quality service and support you rely on.
