Core Technologies
The foundation of AIC innovation
At AIC, every product is built on technologies that guarantee performance, reliability, and sustainability — from our proprietary fire-tube exchangers to advanced stainless-steel bonding.
We design and manufacture complete heating platforms within our own R&D and European production facilities, ensuring high seasonal efficiency, low emissions, and long service life across residential, commercial, and industrial applications.
Fire Tube — Maximum efficiency,
minimum maintenance
AIC’s fire-tube exchangers are developed entirely in-house — from tube forming to certified pressure-vessel assembly. Laser-welded and expanded stainless-steel tubes ensure high heat-transfer performance and minimal pressure drop. Each design is validated through CFD/FEM analysis and tested in dedicated combustion and pressure labs, guaranteeing stable operation under condensing conditions and long-term durability.
Why fire-tube?
- Resistant to poor water or gas quality, less prone to fouling
- Large water volume and natural self-cleaning effect (vertical down-firing design)
- Low pressure drop and high seasonal efficiency
- Certified to PED / ASME standards with full documentation
Stainless Steel — Engineered
for durability and sustainability
At AIC, stainless steel is more than just a material — it’s the foundation of our technology.
With over two decades of in-house expertise in 304L and 316L stainless-steel forming, we control every step of production: tube rolling, shell fabrication, welding, and surface treatment. This full ownership ensures corrosion resistance, mechanical strength, and long-term reliability — even in condensing, high-pressure, and chemically demanding environments.
Why stainless steel?
- Outstanding resistance to corrosion and scaling for extended product life
- High mechanical strength and dimensional stability under cyclic loads
- Suitable for hygienic water, steam, and renewable-energy applications
- Certified European production — compliant with ISO 9001, PED, and ASME standards
