Founded in the United States, DSTI is globally recognized for the design and manufacture of high-tech rotary joints. As Sam Burvee, sales and marketing manager at DSTI, explains, «Our mission is to offer turnkey solutions for applications where the rotary joint or union is a critical component. We work with companies facing new production challenges, integrating added value into our components to ensure long-term performance and reliability». |
Why is this acquisition so important?
Victor Caronni, Marketing Manager at Kadant Johnson Europe & Johnson-Fluiten precisa: «The addition of DSTI to the Kadant group represents a strategic alignment between two companies sharing the same vision: manufacturing excellence, innovation, and customer value. DSTI brings proven expertise in high-performance multi-pass rotary joints, which perfectly complements the engineered systems and sustainable technologies of Kadant Johnson. At Kadant, growth is an integral part of our strategy and culture. Our mission is to provide technologies to improve efficiency, optimise energy use, and maximise productivity. DSTI fits perfectly into this context. Together, we are now better positioned to serve our customers worldwide with advanced technologies that create long-term value.».

Victor Caronni continues: «The acquisition allows us to offer a comprehensive and integrated portfolio. DSTI's added value lies in its proven rotary joint technology and long experience in highly complex applications. European customers can now rely on a single technical and commercial partner for a wide range of rotary joints, from Kadant Johnson's excellence in water and steam applications to Johnson-Fluiten's high-performance segment for machine tools, to DSTI's custom multi-pass solutions». |
What is the technical value of DSTI solutions?
Jeremy Weigel, senior sales engineer at DSTI, explains: «Our multi-pass rotary unions are designed to handle different fluids or gases simultaneously, even under critical operating conditions, with the option of integrating accessories such such as electrical slip rings, fiber optic joints and encoders. Our strength lies in our ability to combine different requirements in a single turnkey solution, optimizing overall size, weight, flow rate, and service life. Each project is the result of close collaboration with the customer, from concept to testing, to ensure maximum compliance to actual conditions of use».
Which sectors will benefit most?
DSTI's expertise and flexibility allows us the ability to meet the needs of sectors with very stringent quality requirements.
Sam Burvee explains: «In the defense sector, DSTI has contributed to the development of next-generation radar cooling systems by designing rotary joints capable of simultaneously managing multiple coolant flows and maintaining thermal stability in extreme conditions. These solutions, adopted for vehicles and ground installations, ensure operational continuity and durability even in environments with high mechanical stress. In the aerospace sector, DSTI's experience has been instrumental in NASA's program dedicated to in-orbit satellite refueling. The company has developed multi-passage rotary joints with extremely high sealing and precision, capable of ensuring the transmission of fluids and signals in vacuum and microgravity conditions, contributing to the success of the orbital refueling mission. In the military sector, DSTI has developed solutions for next-generation vehicle protection systems, where compactness, weight reduction and resistance to shock and vibration are essential elements. Thanks to intensive co-design work with the manufacturer, the integrated rotary joint has improved the safety and responsiveness of on-board systems».
What does DSTI's integrated approach involve?
|
|
Jeremy Weigel: «DSTI manages all stages of the production process internally, from design to testing. We simulate real-world operating stresses to precisely control timing, quality, and performance. Our goal is to deliver a perfect, ready-to-use, risk-free product. Our custom solutions require dedicated engineering time but deliver precise alignment with customer specifications». |
How does DSTI integrate with Kadant Johnson Europe?
Victor Caronni: «The acquisition of DSTI strengthens Kadant Johnson Europe and Johnson-Fluiten’s ability to serve customers with a broader and more complementary product portfolio. DSTI's solutions do not overlap with those already offered by Kadant, but complete them, allowing us to offer European customers a truly comprehensive range of rotary joints and the convenience of a single technical and commercial contact.
DSTI's expertise blends naturally with Kadant Johnson Europe and Johnson-Fluiten’s leadership in high-performance rotary joints. For our European customers, this partnership offers access to a wider range of best-in-class solutions».

New opportunities for emerging sectors
Thanks to DSTI's specialization in customized applications, Kadant is also expanding its presence in industrial segments it did not traditionally serve, such as defense, aerospace, factory automation, Food & Beverage, and renewable energy production. In these contexts, there is strong growth in demand for advanced custom multi-pass rotary joints, devices capable of simultaneously managing the transfer of different fluids through multiple independent channels.

The future vision
DSTI's entry into Kadant group of businesses opens a new phase of growth and international cooperation. From sharing know-how to complementary portfolios, every aspect of this synergy is designed to create value by delivering high-performance solutions and comprehensive global consulting services. The shared vision is focused on improving collaboration between Kadant Johnson Europe and DSTI by combining complementary strengths, specialized expertise, and advanced technologies to deliver superior value to global customers.
