Plasma Clean electrostatic precipitators (ESP’s) are specifically designed for the removal of grease and smoke particles from commercial kitchen extraction systems. These robust units have a low pressure drop resulting in lower energy costs and offer the highest particulate removal efficiency in their class – removing sub-micron particles by 95%.
Plasma Clean ESP’s operate at 95% efficiency at the most penetrating particle size of 0.3μm when operated with a face velocity of 1.8m/s. Always check the stated volume flow and efficiency at the most penetrating particle size (0.3μm) rate when comparing products.
ESP’s work by ionising and trapping grease and smoke particles onto collector plates. They can be configured in single, double or even triple pass depending on the nature of the cooking. The collector plates require periodic cleaning to maintain the high level of efficiency expected from this equipment.
The Plasma Clean “in duct” electrostatic precipitator is a high efficiency pollution control system designed to provide continuous operation and remove more than 95% of the dust, smoke, liquid aerosol and other pollutants from the air passing through them. These are purpose built units with gaskets and an access door located on the specified side(s) for the withdrawal of the filter components.
There are two standard stages of particulate filtration:
• Aluminium mesh pre filters
• Combined ionizer and ESP collector cell to remove grease and smoke particles
After passing through a pre-filter, the particles in the air are given an electrical charge supplied by the power supply. As the particles enter the collector cells, these charged particles are attracted to and collected on grounded collecting plates. Optionally safety filters after the ESP cells can be provided to capture particulates when poor maintenance of the ESP cells allows particulate bypass.
Following the particle control section there are 457mm deep PM18 modules for odour control. The modules are filled with Purafil’s Purakol virgin grade activated carbon. The quantity of carbon provided will ensure that at 1.8m/s face velocity the air will have a minimum gas residence time of 0.09 seconds over the carbon bed, this will provide an initial contact efficiency of 99.7% for the odours.
The system has been designed to sit in the duct run and should be located as close to the cooking process as possible in order to reduce grease content and so leaving the downstream duct virtually grease free. The system has a low back pressure and is hardwired into mains electricity to ensure that the system operates automatically when the extraction system is activated. Full installation and operating instructions are provided.
To maintain optimum collection efficiency, the pre-filters and ionizer/collector cells should be removed periodically and cleaned.
The activated carbon should also be periodically be replaced as the odours begin to break through.
Maintenance can be carried out under a stringent Airepure maintenance contract.
