The Joy of Going the Extra Mile for Our Customers
Step Science operates under the CSE concept, meeting customers directly to understand their true needs and provide services they can trust.
Leveraging over 40 years of technical expertise and proven track record since our founding, our mission is to support the stable quality and precision of products such as semiconductor manufacturing equipment, medical devices, and analytical instruments.
We achieve this by designing, developing, selling, delivering, and providing after-sales service for chilled water circulation systems that meet our customers’ requirements.
01
Expertise and Innovation Built Over 40 Years
For more than 40 years since our founding, Step Science has been consistently engaged in the design, development, and manufacturing of chillers—essential components that support critical fields such as semiconductor manufacturing, medical devices, and analytical instruments.
By sincerely responding to each customer’s request and reflecting their feedback in our product improvement, design, and manufacturing, we have steadily built trust and technical excellence that form the foundation of our company today.
02
Customized Chillers for Diverse Needs
We specialize in the design, development, and manufacturing of custom-made chillers tailored to each customer’s specific requirements — even starting from a single unit.
Through careful consultation and detailed understanding of our clients’ needs, we provide flexible, high-quality cooling and temperature control systems that meet a wide range of applications.
Even in cases where other manufacturers may find it difficult to respond, Step Science may be able to offer a solution. Please feel free to contact us for a consultation.
03
Over 10,000 Units Delivered for Semiconductor and Medical Equipment Applications
To date, Step Science has manufactured and delivered over 10,000 chillers.
Our commitment to high-quality manufacturing and advanced engineering has earned strong trust from clients in fields that demand extreme precision and reliability — such as semiconductor manufacturing equipment and medical devices, where accurate temperature control and safety are critical.
04
Comprehensive After-Sales Service
At Step Science, our commitment goes beyond development, design, and sales.
We have established a comprehensive after-sales support system to ensure that our products can be used safely and with confidence long after delivery.
Through a nationwide network of partner service companies, we provide regular inspections, maintenance, and rapid emergency support to keep our customers’ systems operating at peak performance.
05
From Development and Design to Delivery and After-Sales Service
Unlike many other companies, Step Science provides a fully integrated process — from in-house development, design, and manufacturing to delivery and after-sales service.
This consistent approach ensures stable quality and precision, supporting reliable chiller performance for our customers.
With a strong customer-first philosophy, we deliver long-term trust and peace of mind through every stage of our service.
