TESIO COOLING SYSTEMS INDIA PRIVATE LIMITED

In their own words

Tesio Cooling Systems India – Pioneering Flux-Free Vacuum BrazedCooling SolutionsIndia’s journey towards self-reliance in critical technologies is incomplete withoutindigenous capability in advanced thermal management systems. For decades, coreindustries like Railways, Defence, and Aerospace depended heavily on imports from Europeand China for high-reliability cooling solutions.At Tesio Cooling Systems India, we are rewriting this narrative.Our Unique USP – Flux-Free Vacuum Brazed Aluminium Cooling SolutionsTesio is among the few companies in Asia capable of manufacturing flux-free vacuumbrazed aluminium bar & plate coolers, radiators, and liquid cold plates at scale.Unlike conventional salt-flux brazing, our flux-free vacuum brazing process eliminatescorrosive residues. This ensures:- Superior reliability and durability – zero contamination, no risk of leakage from corrosiveby-products.- Enhanced performance – better thermal conductivity, higher heat transfer efficiency.- Extended service life – especially critical in mission-sensitive Defence and Aerospaceapplications.State-of-the-Art ManufacturingOur production line is designed with global best practices in Lean Manufacturing and SixSigma controls, combining precision and repeatability at every stage:1. Raw material preparation – Aluminium extrusions, plates, and ribbons prepared tostringent international standards.2. Fin and bar forming – High-precision fin and turbulator forming for optimized thermalperformance.3. Core assembly and degreasing – Ensuring cleanliness and defect-free build beforebrazing.4. Flux-free vacuum brazing – The heart of the process, creating robust metallurgical bondswithout impurities.5. TIG/MIG welding of tanks and connections – Delivering structural strength andendurance.6. Leakage testing and quality validation – Each unit undergoes 100% testing underinternational QA plans.7. Chromatization and protective coatings – Corrosion resistance for long service life inharsh environments.8. Final assembly and certification – Every product is validated with 3.1 certification toguarantee traceability and compliance.Applications Across Critical Sectors- Railways – Lightweight bar and plate coolers for locomotives and coaches, reducingenergy consumption and improving operational reliability.- Defence – Liquid cold plates and advanced coolers for armoured vehicles, radar systems,and missile platforms where reliability is non-negotiable.- Aerospace – High-performance thermal management for avionics, satellites, andpropulsion systems operating under extreme conditions.- Emerging Technologies – Supporting EVs, hydrogen fuel cell systems, and renewableenergy storage with efficient, compact, and sustainable cooling solutions.Why Tesio Products Are Best-in-Class- Innovation-driven design – Optimized for high thermal effectiveness with reducedpressure drops.- Proven reliability – Meeting and exceeding European OEM benchmarks; recent approvalswith Siemens underscore our global competitiveness.- Sustainability-first approach – Lightweight aluminium designs lower material usage andenergy consumption across the lifecycle.- Made in India, Globally Trusted – We are enabling India to not just reduce importdependency, but also emerge as a net exporter of critical cooling technology.Tesio’s MissionWe are building more than products. We are building India’s independence in thermalmanagement systems – empowering Railways, Defence, Aerospace, and emerging industriesto rely on world-class technology designed and manufactured in India.Tesio Cooling Systems India – Cooling the Future, Reliably.
