FEL System Light ESP

Building on the reliability and the success of the FE SYSTEM range, thanks to our experience in the application of particular food-agricultural processes, we have been able to conceive and develop the FEL SYSTEM range. This is a new range of active electrostatic filters with built-in electronics, for oil and oily vapour applications. It represents a revolutionary development and a valid alternative to traditional filters. It was conceived to facilitate the use of electrostatic oil filters for specific food processes. Thanks to high separation and oil accumulation capabilities, because of low load losses, it also provides important energy savings. Its multi-pole connection system means that several filters can be connected at the same time, depending on the air load and filtration requirements. In addition, electrostatic filters are installed and removed by simply sliding them across the equipment filter holder frame. The built-in electronic power input circuit is equipped with LEDs to notify the user that the filter is working correctly. A customised range of electrostatic filters for oil and oily vapour applications, without built-in electronics, is also available.

How Efficient Are Electrostatic Precipitators in Filtering Odour and Smoke?

Electrostatic Precipitators are the most effective method used today to control smoke in commercial kitchens. However, filtering by electrostatic forces is only one method. Every brand and every model product works with a certain efficiency by using this method. Here, we come across 2 different variables to filter the smoke in a maximum way. First of all, how many smoke particle we are faced with is very important. The other one is, does the electrostatic precipitator has the power to filter so many particles continuously?

We successfully provided our electrostatic precipitators in many restaurants, cafes, pubs, factories and coffee production facilities around the world. Now we offer our high-performance electrostatic precipitators to the UK. The number of particles released in the “facility” should be calculated correctly to achieve maximum efficiency. Neither a very high capacity nor a low capacity should be offered to customers.

Since electrostatic precipitators filter the particles to a large extent, it reduces the odour considerably. However, it is not possible to eliminate the odour only with an electrostatic precipitator. To remove the odour completely, we provide Ozone generators, UV Systems or Activated Carbon filters to our customers. With these technologies, we can eliminate post-filter odour effectively.

How does an electrostatic precipitator work?

The particles pass through the high voltage electric field region. (ionizer) Here the particles are charged with a positive (+) electric charge. These positively charged particles pass through equally spaced parallel-stacked collecting plates. These surfaces are loaded with negative (-) and positive (+), respectively. Positively charged surfaces repel these particles, while negatively charged surfaces attract and collect them.

Ozcon Electrostatic Precipitators filter 98% of oil vapour and fumes generated during cooking with the right project and equipment selection.

Have a question?

We have the answer!

We’re experts in air treatment and Electrostatic Precipitation technology. If you have any questions don’t hesitate to contact us and benefit our 15+ years of experience.

The Electrostatic Precipitator (ESP) unit utilises the principle of electrostatic precipitation. The dirty exhaust air is drawn onto the mesh pre-filter which traps large grease particles. The remaining finer particles some small as 0.01-micron pass into a strong electrical field (ionising section) where the particulate receives an electrical charge. The charged particulate then passes onto a collector plate section made up of a series of parallel plates. Each alternate plate is charged with the same polarity as the particles repel are grounded, which attract and collect.

Yes! The first rule for electrostatic precipitators is, the higher the velocity the lower the efficiency. The faster the exhaust air travels through the ESP unit, efficiency is compromised. Decision-makers should consider the physical size of the ESP unit, pre-filters, electrostatic cells.

Ozone generator is installed after the electrostatic precipitator. It generates ozone gas and brakes down grease and odour containing compounds producing during cooking. Ozone reduces oil and grease build up in kitchen exhaust ductwork and reduces fire risk. When the Electrostatic Precipitator is in operation and the ozone generator is automatically turned on.

Yes. T Series (HMD) has been independently tested to ASHRAE standard tested 52.2 2017 provides industry accepted procedure for measuring electrostatic filters.

Single-pass efficiency collects up to 98.4% efficiency and double pass efficiency which exhaust air is passed through two units giving it an efficiency of 99.9% and for modular filtration systems, the Ozcon ESP units can be stacked on top of each other to increase airflow (L/s) requirements.

ESP units should be installed as close as possible to the commercial kitchen canopy. This positioning reduces the amount of oil and grease which can accumulate in the ductwork. If your only concern is smoke or you don’t have a place to install it close to canopy you can install it outdoors.

Every cooking style is different, however, on average, the following cleaning schedule applies. These are based upon standard restaurant opening hours:
• Light cooking: every six weeks
• Medium cooking: every four weeks
• Heavy cooking: every two weeks or weekly for charcoal/ solid fuel cooking
