What is Radio Frequency Textile Drying?

Radio Frequency (RF) drying removes moisture from textile products by heating water molecules internally using electromagnetic energy. Unlike conventional drying systems that rely on surface heat transfer, RF energy penetrates directly into the product, resulting in:

Faster and more uniform drying

Lower product temperatures

Reduced colour variation

Improved yarn quality

Higher production efficiency

By drying from within, MagnaTex prevents overheating, shrinkage, yellowing, and surface damage commonly associated with conventional thermal drying systems.

Why MagnaTex?

Uniform Drying. Superior Quality.

MagnaTex uses Strayfield’s proprietary low-density flat plate electrode technology to generate a highly uniform RF field across the entire product width. This eliminates hotspots and uneven temperature zones caused by conventional rod electrode systems.

Better colour retention

Improved moisture uniformity

Reduced yarn damage

Consistent production quality

Strayfield RF drying maintains moisture uniformity within ±1%, ensuring defect-free production and improving downstream process consistency.

Up to 40% Faster Than Conventional Drying

Traditional drying becomes increasingly inefficient at lower moisture levels. MagnaTex RF systems maintain drying efficiency throughout the process, significantly reducing drying times and increasing throughput.

Benefits include:

Up to 40% higher productivity
Faster batch turnaround
Reduced drying line length
Improved production planning

Up to 33% More Energy Efficient

Unlike conventional RF dryers that waste excess power through variable capacitance systems, MagnaTex uses Strayfield’s proprietary Moving Electrode technology to control power directly at the load.

This enables:

Minimal power wastage
Lower installed power requirements
Higher process efficiency
Reduced operating costs

Engineered for the Modern Textile Plant

Automated moving electrodes continuously adjust to product height and moisture levels, ensuring optimal power utilisation and perfect drying performance without manual intervention.

Low-density flat plate electrodes distribute RF energy uniformly across the product, eliminating intermittent hotspots and preventing product damage.

Twin extraction fans ensure even moisture removal, reducing cycle times and preventing damp pockets within the product load.

The fully welded aluminium structure improves conductivity, enhances safety, minimises RF leakage, and ensures long-term structural durability.

Touch controls and live internet connectivity allow live remote monitoring, instant troubleshooting and trend analysis.

Installations last 35+ years, with thousands operating globally and new systems continually being added across markets worldwide.

A single machine processes all textile formats and blends, quickly adapting to batch and product changes.

Durable consumables cut costs and maintenance, boosting output and total machine value.
