AIR TREATMENTKitchen exhaust systems provide a means to remove heat and contaminants (smoke, grease aerosols, and water vapor) generated during cooking operations. While exhausting these items provides a better indoor environment, it can cause problems outdoors to neighboring facilities due to the associated odors and particulates emitted.

The amount and type of contaminants generated from a kitchen exhaust application will depend on the cooking operations taking place inside. The contaminants include gases, vapors, aerosols, and particulates. Therefore, kitchen exhaust filtration must incorporate a wide range of filtration types and be versatile to provide an adequate solution.

Commercial kitchens typically include grease and moisture capture devices at the cooking locations. These may be in the form of hoods with baffles or other equipment to remove the initial amount of grease aerosols and particulate. The exhaust air stream will have carryover of contaminants that are not removed by these devices, or from cooking operations that do not use removal devices at the cooking location.

THE O.N. 100 ODOR NEUTRALIZERHow it works and its use in the control of odors from commercial kitchen extract systemsThe O.N. 100 has been developed by Purified Air Limited using patented technology which combines physics and chemistry to encapsulate and treat cooking odors being emitted from restaurants and other commercial cooking applications. There is high demand world wide for the O.N. 100 and associated products which are easy to install and maintain. When applied correctly, the O.N. can reduce the odors emanating from cooking premises by as much as 90%

The O.N. 100 installed on a flat roof with ESP 3000 E prefiltration unit.

ELIMINODORThis unique product has been blended solely for use in Purified Air Product to counteract cooking odors from the exhaust of restaurants and commercial cooking operations. ELIMINODOR has been developed using space-age technology and is a finely-balanced blend of oils and other chemicals which neutralize cooking odors. This blend must not become unbalanced by mixing with any other products as this will render ELIMINODOR ineffective and result in damage to the equipment. The design of this unique system provides that only minimal quantities are required for optimal results. Approximate dosage: One liter per three weeks under normal conditions. ELIMINODOR combined with Purified Air Systems can eliminate nuisance caused by cooking odors by up to 90%

ODOR NEUTRALIZATION

How it worksThe air stream must first be cleaned of the majority of particulate contaminants made up of hydrocarbons and grease vapors leaving the gaseous phase (odor) the be treated by the O.N. 100. Ambient air is drawn into the unit and mixed with a specially-blended neutralizing chemical. A vapor is formed which is then ionized to a negative potential of 15,000 volts. The ionized vapor passes along a non-conductive tube and is discharged into the center of the duct via a venturi spigot. The metal duct is grounded through the same high-tension circuit which makes the contaminant at an opposite potential to the negatively-charged vapor. The electrostatic difference between the contaminant and the neutralizing vapor causes the two to combine electrically after which a chemical reaction takes place to treat the malodor.

MaintenanceThe O.N. 100 needs to be topped off with a chemically-formulated neutralizing agent on a regular basis. In an average situation we advise two to six weekly servicing, dependent on usage.

Electrostatic Precipitators.Electrostatic precipitators are used to clean the air stream of grease and hydrocarbons (smoke). These highly-efficient units can remove particles as small as 0.01 microns at an efficiency in excess of 90%. This equipment would be used before the O.N. 100 in our systems with a high carry over of grease or smoke. The units come in modular form, shown is the ESP 3000E, which is suitable for airflows of up to 5,000 cubic meters per hour (3,000 CFM).

SECTIONS

Grease and Smoke (Particulates)The air stream must first be cleaned of the majority of particulate contaminants made up of hydrocarbons and grease Green Energy Ecology Units remove the particulate contaminants (grease aerosols, moisture, other particulate) that are carried over into the exhaust air stream using electrostatic precipitators in combination with the appropriate stages of particulate filters. These include metal washable filters, high capacity bag filters, and high efficiency (MERV 16) pleated filters. In applications with lighter loading of particulates, solutions may solely use stages of particulate filters. In both cases, it is critical to performance and safety that proper maintenance, cleaning, and replacement are performed as required for the application.

CHOOSING SYSTEM COMPONENTS

Odors (Gases)Odors result from the release of volatile organic compounds during cooking operations. These volatile organic compounds are in the gas -phase; they are not removed by the particulate contaminant solutions mentioned above. The most widespread solution to remove these compounds is activated carbon applied in filtration cells such as metal cassettes or canisters. In some instances, applications have used a blend of activated carbon and other media. The filtration cells are commonly designed to achieve at least 0.1 seconds of residence time, however, the actual configuration and associated residence time will depend on the cooking operations taking place inside the kitchen.

Absolute HEPA FiltersWe supply a range of HEPA filters to suit your needs. To qualify to be called a High-Efficiency Particulate Air (HEPA) filter, the filter must be able to remove, from the air that passes through it, 99.97% of particles down to a sub-micron level of 0.3 microns. Our main use of HEPA filtration is the removal of smoke particles.

Passive filtration is a major component in any air purification system. Passive filters can capture a large amount of grease and particulate before it reaches the electrostatic precipitator (ESP). Certain passive filters can be used after the ESP stage when the system requires additional cleaning. Green Energy offers a complete line of passive filters designed to work with the other components in your system to provide optimal results.
