Fluidnatek HT: Industrial Electrospinning Machine for High-Throughput Nanofiber Manufacturing

Built for extended manufacturing runs (e.g. 24/7), the industrial Fluidnatek HT platform integrates real-time process monitoring, automation, and comprehensive data collection to improve traceability, process insights and manufacturing consistency.

Bioinicia Fluidnatek’s experience in electrospinning goes beyond equipment design. Our mother company, Bioinicia, completed the world’s first GMP-certified electrospinning manufacturing plant for electrospun pharma products in September 2017, having that facility back then a capacity of over 10 million oral drug delivery patches per year. This background gives the Fluidnatek HT landing strong authority for buyers evaluating industrial readiness, validation potential, and long-term process reliability.

The Fluidnatek HT also supports modular expansion with options and ancillary equipment such as calendering, activated carbon filters for solvent management, in-line air permeability quality control, semi-automated solution refilling, and a 200 L solution mixing system. This makes it adaptable to different production needs in large area coating applications, without changing the core electrospinning platform.

Its automation layer includes programmable recipes (process automation), batch control, user-level access, remote visualization and commanding, and the Fluidnatek Process Data Hub for real-time deep process monitoring. Together, these functions reduce operator variability and improve traceability in industrial workflows.

Why Industrial Electrospinning Requires Tight Process Control

Industrial electrospinning requires extremely stable operating conditions and process control over long production runs to maintain consistent morphology of the fiber-based structure, layer uniformity, batch-to-batch consistency, and system-to-system matching. Otherwise, consistent manufacturing every time and product validation is nearly impossible. Small variations in solution delivery, environmental conditions, air distribution, electrical field, collector speed, voltage, jet interference, or other variable, can substantially affect product quality, product performance, and manufacturing efficiency.

The Fluidnatek HT electrospinning industrial platform addresses these challenges through integrated process automation, precise environmental control, real-time monitoring systems, advanced engineering solutions, and advanced data collection in real-time for data-driven decisions. This leads towards a tight process control, where all variables affecting the process are carefully optimized. By combining these capabilities within a single industrial platform, manufacturers can achieve process repeatability, consistency every time and system-to-system matching, while generating the traceability required for quality management and regulated production environments.

Continuous Industrial Manufacturing

Unlike laboratory systems aimed primarily at research, the Fluidnatek HT electrospinning industrial platform is designed for continuous industrial production (24/7) in large area coating applications. Its roll-to-roll 1.6m width setup supports uninterrupted nanofiber manufacturing with consistent web/substrate handling across extended runs.

This electrospinning platform combines a multi-emitter spinning injectors (up to 5000 emitters/needles), automated substrate transport and self-alignment, precise motion control, in-line metrology systems, and configurable process parameters to support stable operation during extended production cycles. This integrated approach helps manufacturers continuous manufacturing while maintaining consistent deposition quality across the entire substrate width.

Its design also allows the system to be configured according to specific production requirements, making it suitable for organisations developing industrial-scale electrospinning processes across a wide range of materials, solvents, and applications that require enough degree of flexibility and adaptability, even if it is an industrial platform intended for mass production.

Climate-Controlled Electrospinning

Maintaining stable environmental conditions is one of the key factors for achieving reproducible electrospinning. This is even more important at industrial scale. The Fluidnatek Environmental Control Unit (ECU) provides precise regulation of spinning chamber temperature and relative humidity, helping manufacturers establish stable processing conditions throughout extended production runs.

The ECU supports independent heating, cooling, drying, and humidifying functions in a closed-loop environment, allowing process conditions to be adjusted according to material requirements and manufacturing objectives.

Unlike conventional climate control systems, the Fluidnatek ECU has been specifically developed to perform well in a particular evaporative process such as electrospinning, where temperature and humidity directly influence solvent evaporation, jet stability, fiber morphology, and overall process reproducibility.

The Fluidnatek Environmental Control Unit regulates chamber temperature from 20°C to 45°C (±1°C) and relative humidity from 10% to 80% RH (±3%).

To maximise process stability, the Fluidnatek ECU operates in synchrony with the actively regulated exhaust system. Together, these systems optimise solvent extraction, maintain a controlled slight negative pressure inside the chamber, and help minimize process variability during manufacturing.

High-Throughput Roll-to-Roll Production

The Fluidnatek HT combines continuous roll-to-roll handling with high-throughput electrospinning multi-emitter injectors (or alternatively using the Fluidnatek needle-less Slit Injectors). The industrial roll-to-roll system supports a maximum width of 1600 mm, adjustable linear speed range, tension control, and active alignment control.

The machine uses linear multi-emitter spinning heads and can be configured with maximum of 30 spinning injectors and up to about 5000 emitters/nozzles overall. This allows the platform to support large-area nanofiber coating production while maintaining controlled deposition conditions.

Industrial Process Control and Data Traceability

Reliable high-volume electrospinning requires much more than increased production capacity. Maintaining consistent product quality throughout extended manufacturing runs depends on continuous monitoring, process stability through a tight process control provided by multiple technical solutions (including environmental control and many others), and comprehensive data collection.

The Fluidnatek HT incorporates the Fluidnatek Process Data Hub, providing real-time monitoring of more than 40+ process parameters and equipment signals throughout production. This allows operators to visualise critical variables and process information, analyse manufacturing performance, and identify early process deviations before they affect product quality.

The Fluidnatek HT electrospinning industrial platform also integrates programmable sequential recipes (process automation), batch management, user-level access, in-line metrology systems, environmental control, and the mentioned high-definition process data collection. Together, these capabilities improve traceability, reduce operator variability and errors, and simplify process optimization across multiple manufacturing batches. Importantly, with in-line metrology systems, the batch rejection rate can be taken nearly to zero.

For manufacturers operating in regulated environments, comprehensive process documentation also facilitates quality management, process validation, and long-term manufacturing consistency.

Automation for Batch-to-Batch Consistency

Maintaining consistent electrospinning performance across multiple production batches is essential for industrial manufacturing. The Fluidnatek HT electrospinning industrial platform combines automated process control with configurable production recipes to minimize operator intervention and improve manufacturing repeatability.

Recipe management allows complete production parameters to be stored, reused, and continuously refined as manufacturing processes evolve. User-level permissions and batch control further support controlled operation across different production teams and manufacturing shifts.

By combining automation with comprehensive process monitoring and in-line metrology systems, the Fluidnatek HT helps manufacturers achieve unmatched batch-to-batch consistency while reducing process variability and simplifying scale-up activities.

Customizable Industrial Electrospinning Platform

Industrial electrospinning applications often require different process configurations depending on the material processed, substrate characteristics, production volume, and downstream manufacturing requirements.

The specific architecture of the Fluidnatek HT electrospinning industrial platform allows the platform to be configured according to specific manufacturing needs. Optional equipment such as in-line calendering, activated carbon for solvent management, in-line air permeability quality control, semi-automated solution refilling, and a 200 L solution mixing system, further expand production capabilities while supporting higher levels of automation.

This flexibility of configuration enables manufacturers to adapt the system as production or process requirements evolve without fundamentally changing the underlying electrospinning platform.

Inert Atmosphere in the Spinning Chamber

When using flammable solvents, a considerable amount of solvent vapour is generated by an industrial electrospinning platform such as the Fluidnatek HT for mass production. In order to mitigate any risk, a nitrogen-based environment is created in the spinning chamber of the Fluidnatek HT, this way achieving an inert atmosphere (like ATEX), always below the Lower Explosion Limit (LEL). This guarantees maximum safety for operators, as well as enable to process applications requiring absence of oxygen.
