What ATT Advanced Thermal Technologies does

ATT Advanced Thermal Technologies GmbH is an Austrian private company founded in 2014 and headquartered in Dobl near Graz, operating as a member of the Naxnova Group since 2024. The company designs and manufactures ultra-thin, flexible printed heating foils and temperature sensors using screen-printing processes on flexible substrates. Its core technology platforms are carbon-based Positive Temperature Coefficient (PTC) self-regulating heaters, precision silver resistive heaters, and Negative Temperature Coefficient (NTC) temperature sensors — including patent-protected NTC sensors under 25 μm thick that can be integrated with the heaters into a single foil and overmolded into plastic parts. The company also develops the supporting electronics (PCBs, firmware, application software, and prototype ECUs) and runs the manufacturing in a cleanroom production environment.

ATT serves B2B enterprise customers across five verticals: automotive (ADAS sensor and camera heating, vehicle cabin heating, battery heating and diagnostics, seat heating and sensing, SCR tank heaters for AdBlue/DEF systems), aerospace (aircraft floor heating, de-icing, sensor protection), rail vehicles, defence, and industrial processing. Named enterprise customers and partners include Airbus, Safran, MTU Aero Engines, Daikin, GEA, Vincorion, AIT Austrian Institute of Technology, Dell'Orto, and Backhug. Technologies have been qualified to VW80000, ISO 9001:2015, automotive industry quality, aerospace industry standards, RoHS, REACH, IMDS, and UL 94 V0.

The business model combines custom-engineered heater and sensor manufacturing (hardware sales, project-based with series production) with paid engineering, development, and feasibility services spanning specification, simulation, prototyping, industrialization, and ongoing series production. Pricing is quote-based and varies with geometry, complexity, volume, and integration method. Go-to-market is direct enterprise field sales into OEM and Tier 1 engineering organizations, with early-involvement design collaboration, multi-language corporate web presence (German, English, French, Italian), and participation in automotive, aerospace, and thermal-management industry events. The company is led by CEO Ankur Lodha and reports 11–50 employees.

Revenue model

1. Custom Heater Foil Manufacturing: ATT designs and manufactures custom ultra-thin printed heating foils (PTC and silver resistive) for specific customer applications. Revenue is generated through project-based development fees followed by series production of custom heating elements. Solutions are tailored to customer geometry, power requirements, and integration methods.
2. Custom Sensor Manufacturing: Custom-printed NTC temperature sensors manufactured to customer specifications. Sensors are sold as components for integration or as part of complete solutions (e.g., battery diagnostic sheets with ECU and CAN interface). Revenue from sensor component sales and complete diagnostic systems.
3. Engineering and Development Services: Full engineering services from concept through prototype to series production. Includes specification phase (generally free consultation), paid feasibility studies for complex projects, design engineering, prototyping, industrialization, and ongoing production support. Services cover thermal analysis, heater/sensor design, simulation, and qualification testing.
4. Electronics Development: Complete electronics development from concept to prototype ECU, including circuit design, PCB layout, firmware, and application software. Provided as part of integrated thermal solutions or as standalone development service.
