Radio frequency dryer RFA/S COMBO

Overview
The RFA/S COMBO series are combined radio‑frequency and forced‑air industrial dryers designed for textile processes. Independent forced‑air drying sections are integrated into the standard RFA/S configuration to create a twin‑power system where RF (electromagnetic) energy and conventional hot‑air drying can be dosed and controlled independently via PLC.

Operation and control

• PLC control enables separate modulation and dosing of RF energy and forced hot air.
• Hot‑air temperature and air flow are adjustable independently to match material requirements.
• The optimal RF/air combination is selected according to the chemical, physical and dimensional properties of the substrate to maximise evaporation efficiency and product quality.

Applications
The RFA/S COMBO dryers are suitable for a wide range of textile substrates. Best performance is achieved with low‑density materials such as loose fibres, unwound tow/top slivers and yarns in hanks, where forced air assists evaporation, promotes fibre bulking, reduces internal temperature and minimises the risk of overheating or scorching temperature‑sensitive products.

Design and flexibility
Modular construction allows easy sizing for different production capacities. Specific PLC software for the RFA/S COMBO series permits precise process optimisation for each substrate and consistent integration with production lines.
