QUALITY

Sesino lives quality as a daily, ongoing commitment that started over one hundred years ago in the workshop and today is structured in a certified system focused on continuous improvement.

Each air–oil, water–oil or shell and tube heat exchanger is the result of this journey: long‑standing expertise, strict quality controls, selected materials and close attention to the real operating needs of customers’ plants.

Quality rooted in history

Since 1919, Sesino has been designing and manufacturing thermal solutions, moving from the first radiators for vehicles to modern heat exchangers for hydraulics and industrial applications. This continuity makes it possible to turn field experience into ever higher quality standards, with products engineered to operate for a long time under demanding conditions. Over time, quality has become a true working method: attention to detail, tight tolerances, in‑process and final inspections, component traceability and technical support before and after the sale. Every product evolution – from historical series to the latest high‑pressure and fully bespoke solutions – stems from this solid foundation of reliability.

ISO 9001 certified quality system

Sesino’s commitment is formalized in a quality management system certified according to ISO 9001, which governs processes, responsibilities and controls along the entire value chain.

ISO 9001 certification confirms that design, sourcing, production, testing and service follow defined, monitored procedures oriented towards continuous improvement. For customers, this means heat exchangers with consistent performance, clear documentation and processes audited by independent third‑party bodies. Quality does not only concern the finished product, but also response times, technical support and the ability to guide customers towards the most suitable heat exchanger.

Inspections, testing and material selection

Every Sesino heat exchanger is developed starting from precise application requirements: thermal duty, pressure, fluids, environmental conditions and plant layout. The selection of materials, treatments and construction solutions is driven by durability, pressure and corrosion resistance, safety and stable performance over time. Products undergo dimensional checks, leak tests and, for more complex solutions, mechanical and thermal verification according to international standards such as EN, ASME and PED. For high‑pressure and critical applications, advanced calculation and simulation software is used to validate component behaviour under real operating conditions.

Quality as customer service

For Sesino, quality also means supporting the customer at every stage: from choosing a standard model to designing fully custom heat exchangers. The technical team helps define the most suitable solution, taking into account not only thermal power, but also footprint, installation, maintenance and operating costs. Dedicated calculation tools, comprehensive technical catalogues and a network of selected distributors make it easy to identify the right heat exchanger and receive qualified assistance. The goal is to ensure more reliable plants, fewer unplanned stops and more efficient heat management, with a positive impact on costs and productivity.

Quality, efficiency and sustainability

Sesino product quality is closely linked to energy efficiency and sustainability: higher‑performance heat exchangers mean lower energy consumption, less waste and longer system life. The heat exchanger ranges, including the latest series and special solutions, are designed to offer the best balance between thermal performance, size, noise level and environmental impact. This approach makes Sesino a reliable partner for companies looking for certified, long‑lasting heat exchangers that support concrete efficiency and sustainability targets in their processes.

It is a commitment that starts from the company’s history and continues every day, in every new thermal exchange project developed together with customers.

ISO 9001:2015 and ISO 45001:2018 certifications

ISO 9001:2015 confirms a structured quality management system aimed at the continuous improvement of processes, products and customer service.
ISO 45001:2018 certifies the company’s focus on occupational health and safety, with procedures that protect people and ensure controlled working environments.

Together, these certifications demonstrate an integrated approach to quality: reliable heat exchangers manufactured safely and responsibly along the entire production chain.
