We do ventilation. And we do it well.
Filtration
We have developed the most advanced ESP filtration system available on the market with unrivalled performance, all with a fully sustainable maintenance regime.
Innovative design to eliminate grease and smoke particles
Maximum efficiency, minimum space: Chapman Ventilation’s Electrostatic Precipitator (ESP) is the most sustainable and efficient way of removing grease and smoke from kitchen emissions.
Why electrostatic precipitation?
It’s simple – an ESP provides the highest level of efficiency available today. Up to 95%, in fact. Gone are the days of costly, space-consuming and non-recyclable filters that send tons of waste to landfill every year. Instead, electrostatic precipitation offers a truly sustainable and lowmaintenance option. It uses an electrostatic charge targeted specifically at grease and smoke particles to remove these contaminants from the air stream, causing them to form a film inside the ESP unit.
The modular design
Chapman Ventilation specialises in creating bespoke integrated solutions. That’s why our robust ESP units can be configured to accommodate any air flow, and provide unrivalled filtration of grease and odours.
How does it work?
The Technology
Grease and smoke particles in the air stream are negatively charged by central cathode needles. This causes the charged particles to migrate towards the surrounding cylindrical anode collection tubes, where they settle and form a film.
Our ESP system also generates ozone to react with the oxidisable odours and in addition the high voltage electrostatic field works to break down the covalent bonds on the odour molecules. This dual action significantly but not entirely reduces the overall odour at discharge.
Here at Chapman Ventilation , we are continuously improving our products to ensure that they are the most effective and efficient pieces of equipment on the market today.
Features
The cathode needles are positioned centrally within the cylindrical anode collectors. This ensures a constant, robust and improved ionisation field.
A flow-equalisation plate removes large particles and encourages even air-flow distribution across the cells, thereby increasing efficiency.
Our systems now generate ozone to help reduce odours from kitchen emissions.
Typically, existing ESP technology only allows for an inlet velocity of 3-4 m/s. Chapman Ventilation’s ESP can handle three times that. Our unites are able to handle velocities up to 10 m/s with no detrimental effect on performance.
We have solved one of the major problems consistent across all ESPs until now: the need to swap out cells as part of a monthly cleaning cycle. We have developed a technique that allows us to clean cells on site there and then, without having to remove and replace them.
Patented technology varies power delivery, ensuring efficient particulate removal.
Maintenance
With no moving parts, an ESP requires little but often active maintenance. A regular cleaning routine in order with the density of pollution generated ensures that your ESP is always performing at its optimum efficiency. Your representative will be able to guide you through the details. Each module features a clear, illuminated display that indicates when a service is required. For the most part, servicing is simple. The filter cells are thoroughly cleaned and de-greased on site that day by one of our experienced engineers. Our technology means the cells to not have to be taken off-site to be cleaned. This is a unique service. Not only does it reduce time and cost but it can also increase service intervals and system efficiency.
