Since its foundation in 1968, Folplast Kft. has been a major player in Hungarian packaging manufacturing. As a specialist in polyethylene (PE) products, the company's development is driven by continuous technological modernisation and a commitment to sustainability. In modernising its production processes, Folplast pays particular attention to indoor air quality, and therefore launched a comprehensive air treatment project integrated with heat recovery in its extrusion plant.
The challenge: special pollutants at extreme height
The extrusion process generated significant amounts of airborne pollutants, mainly polyethylene and paraffin particles, which accumulated near the ceiling. The air purification system had to remove these pollutants effectively and operate reliably at a height of 10–12 metres, all with minimal maintenance. It also had to integrate with the existing HVAC system and meet safety requirements, including zero ozone emission.
Several critical obstacles had to be overcome during the project:
- Efficiency: A system had to be found that could completely remove fine industrial particles.
- Maintainability: As the units were installed at a height of 10–12 metres, infrequent and simple maintenance was a basic requirement.
- Integration: The solution had to fit the existing HVAC (heating, ventilation and air conditioning) network.
- Safety: Strict requirements had to be met, including fire protection and zero ozone emission.
The solution: AirQuality FKE-G technology
On the recommendation of its expert partner Nuxon Kft., Folplast chose AirQuality Technology FKE-G series electrostatic precipitators (ESP).
This industrial solution was developed specifically for high-efficiency filtration of fine particles. The main features of the system:
- Robust design: Aerospace-grade aluminium plates resist corrosion and carbonisation, guaranteeing a long service life.
- High capacity: Thanks to the large collection surface, the system needs less frequent cleaning, which is crucial for hard-to-reach installations at height.
- Fast servicing: The patented ESP cells dry within an hour after cleaning, so production downtime is minimal.
- Green technology: The system operates without ozone emission and features UL-compliant insulation and certified fire protection solutions.
| Parameter | In the upper zone of the hall | In the purified, returned air | Separation efficiency |
| PM2.5 level | 144 µg/m³ | 8 µg/m³ | 94,40% |
| PM10 level | 168 µg/m³ | 9 µg/m³ | 94,60% |
The improved air quality and low-maintenance operation met the client's expectations, contributing to a cleaner and safer working environment. With this investment Folplast Kft. has once again shown that efficient industrial production and environmental awareness can go hand in hand.
