HeFeng Modules
II- HeFeng Modules (A → J)
A — Narrow-Web Corona Station
Technical Advantages
- HeFeng-Home-Set fine gap adjustment with electrode stop for system protection and repeatability.
- HV cable routed outside the ozone-exhaust area → improved anti-corrosion, longer electrode life.
- German-patented ceramic fin electrode ensures powerful, homogeneous, uniform treatment on plastics, aluminium, multilayer and metallised films, and paper.
- Minimal downtime for service/cleaning: HeFast-Change cassette, tool-less removal; all materials are ozone/corrosion-resistant.
- Open design with front inspection window for visual process control; one electrode length covers varying web widths.
- Easy cleaning of the electrode assembly and exhaust duct on the workbench.
- HeFast-Change cassette: simple maintenance, easy threading and fast changeovers; easy retrofit or new-line integration in any position.
B — Wide-Web Corona Station
Technical Advantages
- New corona treater with adjustable gap and safety stop.
- HV cable separated from ozone exhaust area to avoid corrosion and extend service life.
- German fin ceramic electrode: powerful, homogeneous, uniform treatment on plastic films, aluminium foil, multilayer films, metallised films and paper.
- HeFast-Change cassette built from anti-oxidation/anti-corrosion materials: quick cleaning & maintenance without tools, reducing downtime.
- Open, pivoting electrode design makes web threading and material changes easier; auto open/close for thick substrates → higher efficiency.
C — Corona Generator
Technical Advantages
- Intelligent multi-function control with LCD touch screen.
- Four modes: local panel, corona station detection, remote, and automatic.
- Ozone fan start mode and stop-delay selectable.
- Multiple process-state alarms and equipment protection alarms.
- Multi-language UI; RS-485/Modbus support; Wi-Fi optional.
D — High-Performance Generator
Technical Advantages
- Power range 1–40 kW (multi-channel 2×1 kW to 4×40 kW)
- LC-Display or TFT panel; readout in Watts and/or corona dose.
- Advanced settings: thickness recognition, crosswise skip-treat (bag printing), speed-based power adaptation.
- Multi-language selection via display.
Options
- Power control analog or via fieldbus.
- Process monitoring with memory and USB.
- UL/CSA versions.
E — Ozone Converter
Technical Advantages
- Metal-oxide catalyst bed converts O₃ → O₂.
- High safety: non-flammable catalyst (no activated carbon).
- Long service life via dual pre-filters (dust/fibres) protecting the catalyst.
- Fast maintenance with exchangeable filter boxes.
- Size matched to exhaust flow of the corona system.
- Stainless-steel housing & piping, downstream exhaust fan, compact & durable design.
- Environmental protection by avoiding harmful emissions.
F — Plasma Treater
Technical Advantages
- Single- or double-sided web treatment; custom working widths
- Metering of gases and mixtures (N₂, CO₂, Ar, O₂/N₂, …).
- Ceramic-coated chill/backup roller with temperature control.
- Stainless electrode chamber rotatable 180° for easy servicing.
- Full enclosure with configurable slit systems.
- Cartridges for multi-point gas distribution; pressure controllers for accurate dosing.
- In-line port for gas-concentration measurement.
- Gas consumption and max speed depend on substrate/setup.
G — Contact Web Cleaner
Technical Advantages
- Designed for medium to wide webs; single or double-sided cleaning.
- Elastic cleaning roller with pneumatic loading for even pressure; removes dry, non-adhesive contaminants.
- Anti-stick paper (collector) with pneumatic open/close transfers particles from the roller for easy collection.
- Electrostatic neutralization to minimize re-contamination.
- Compact build: quick change of dust roller and paper, easy install & maintenance.
- Self-adhesive rollers (silicone/PU), mirror-smooth (< 2 μm), available in low/medium/high tack.
- Applications: coaters, printers, cleanrooms, films, labels/PSA, photovoltaic, pharma, etc.
H — High-Efficiency Non-Contact Surface Dust Removal
Principle & Advantages
- Non-contact cleaning to avoid surface damage.
- Optimized cavity design converts blower high-pressure airflow into a very high-velocity jet (ultrasonic-like effect) for efficient particle removal.
- Durable, easy to install/maintain, compact footprint.
- Stable performance without attenuation.
I — Electrostatic Eliminator (Ionizing Bar)
Applications
Plastic films, laminators, blown-film, coaters, printing, slitting, etc.
Technical Advantages
- Safe, shockless, touchable.
- Fast, thorough static elimination → fewer defects and reduced fire risk.
- Latest technology, CE certified.
- Bar length up to 4 m.
- Sealed aluminium body: moisture/dust-resistant; easy mounting.
J — Electrostatic Charging System
Technical Advantages
- High-voltage charging for electrostatic spraying, electrostatic bonding, dust removal, etc.
- Full electronic protection: short-circuit, over-voltage, over-current.
- Continuously adjustable output voltage/current with high-precision LED readout.
- Modular internal design, compact, stable for long-time operation.
- Soft-start control; local and remote operation.
- Customizable to user requirements.
