Grease Filtration Technologies Explained
Understanding how grease filtration works is key to choosing the right system for your kitchen. In the UAE, several technologies are available, each suited to different cooking volumes, kitchen layouts, and budgets.
Electrostatic Precipitator (ESP) Systems
ESP systems use an electrical field to charge grease particles as they pass through. These charged particles then stick to oppositely charged collection plates, where they accumulate and can be easily cleaned off. The process starts with air passing through a pre-filter, followed by an ionisation chamber that charges any remaining grease particles. Finally, the particles are collected, and clean air exits the system.
ESP systems can remove 95% or more of grease particles, making them highly effective for high-volume commercial kitchens. They are especially good at capturing larger grease particles, and their maintenance is simple - collection plates can be reused after cleaning with a degreasing solution.
This technology is ideal for kitchens with heavy grease and smoke production, such as those specialising in grilled meats or fried foods. It’s a reliable option that doesn’t require frequent filter replacements.
Next, let’s look at how multi-stage systems take air quality a step further.
Multi-Stage Filtration Systems
Multi-stage systems combine ESP technology with additional filters, such as activated carbon and ionisation stages, to tackle grease, odours, and fine particles.
Activated carbon is excellent at absorbing odours and volatile organic compounds (VOCs). Some advanced systems also include ionisation stages to remove bacteria, fine particles, and gases, delivering overall filtration efficiency of over 99% for superior air quality. While carbon filters do need periodic replacement, the improved air quality they provide makes these systems especially useful in settings where odour control is crucial, such as mixed-use buildings.
These systems are particularly suited for bakeries, restaurants in shopping centres, and residential kitchens where odour and fine particle control are priorities.
Now, let’s compare these technologies to find the best fit for your kitchen.
Filtration Technologies Comparison
Choosing between ESP and multi-stage systems depends on your kitchen’s specific needs. ESP systems are excellent for grease removal with minimal maintenance, making them a cost-effective choice for standalone restaurants or catering facilities where odour control isn’t a top concern. On the other hand, multi-stage systems offer comprehensive air treatment by addressing grease, odours, fine particles, and VOCs. This makes them perfect for kitchens in sensitive locations like shopping malls, hotels, or residential buildings.
Some multi-stage systems also support air recirculation, eliminating the need for vertical duct risers - a major advantage in urban areas where rooftop access is limited.
Both ESP and multi-stage systems are designed to minimise ozone production. Certified units emit ozone levels over 25 times lower than regulatory limits. For kitchens with heavy fume and odour production, such as those involved in frying or grilling, high-efficiency filtration is crucial.
Ultimately, the choice comes down to your cooking methods, location, and specific requirements. A standalone restaurant focusing on grilled meats might find an ESP system sufficient, while a café in a residential tower would benefit more from the odour and air quality control provided by a multi-stage filtration system.
