NEOHEATER®: Flexible heating films for integrated thermal management

NeoHeater® refers to a range of flexible heating films designed to integrate a heating function directly into an industrial system. ADDEV Materials develops, transforms, and adapts these solutions for the Power & Mobility markets: energy, energy storage (BESS), automotive, rail, data centres, and industry. Each project is sized according to the active surface area, power, voltage, geometry, and integration constraints. ADDEV Materials' converting capabilities allow for the delivery of ready-to-integrate formats: laminated film, die-cut part, or sub-assembly with connectors.

NeoHeater®: thin, flexible and integratable heating technology

NeoHeater® rests on printed, etched, metallic or resistive heating architectures, depending on the selected range. The thermal function is integrated into a technical film or a suitable substrate, in order to generate homogeneous heat as close as possible to the zone to be heated.

The range covers four technologies: NEO-RS for resistive polyimide films, NEO-FOIL for heating circuits on substrates, NEO-TRACK for printed or etched conductive tracks, and NEO-CH for transparent metal mesh-based heating films.

This approach reduces bulk, limits hotspots and facilitates integration into battery systems, technical modules, railway equipment, technical cabinets and cold-exposed industrial devices.

Why NeoHeater® meets integrated thermal management constraints

NeoHeater® is the preferred choice when the application requires controlled temperature rise, seamless integration and uniform heat distribution. The four criteria below provide a quick way to assess the benefits of this technology compared to silicone heating elements, PTC heating elements or heating cartridges.

Thin and flexible film — compact integration

Uniform heating — hotspot limitation

Bespoke design — tailored geometry and power

Rapid rise — target temperature in less than 1 min per design
