KMA AAIRMAXX® ESP tube electrostatic precipitators are highly effective in separating coarse and fine particles, solid substances and liquid droplets from the air. The smoke and dust particles are led vertically (from bottom to top) through the filter body. A stainless steel iIonization electrode inside the separating tube forces the aerosols and particles against the metal wall of the filter body.

From there the separated substances can be removed continuously (e.g. through a fine water film) or discontinuously (through knocker, steam, CIP-water). In this way, also sticky or greasy substances as grease, sticky dusts and similar can be removed from the air without clogging the filter system. AAIRMAXX® electrostatic tube filter are often used for exhaust air with higher concentrations of emissions.

During the filtration of the exhaust air the recovery of process heat can be achieved by the integration of a heat exchanger. Industrial exhaust air contains often valuable heat, which can be used for follow-up processes.

In the case of low exhaust air temperatures the heat recovery can be optimised by the combination with the KMA Ambitherm® high efficiency heat pump. The heat extracted from the exhaust air is available for warming water or heating the building.

As the heat exchanger is installed directly next to the filter zone, it can be cleaned regularly automatically simultaneously with the filter module.

The scrubber is designed for the separation of odour, gas, and fumes, and operates according to the absorption principle.

Gas and fumes contained in the waste air are first captured and then separated by an appropriate washing liquid.

The KMA gas scrubber is characterized by high separation performance and low water consumption.

The scrubber can also be used as a humidifier before waste air enters into the biological filter.

ULTRAVENT® Electrostatic filter cells allow the high-grade separation of smoke, dust, fine mist and also sticky or greasy aerosols. “Blue haze” caused by the use of release agents gets separated effectively as well.

The energy consumption of our electrostatic filter cells for an exhaust air volume of 5.000 m3/h meets the energy consumption of a 100 W light bulb.

UV light serves for the photo-oxidation of odours. Many malodorous VOC molecules can be oxidised by means of UV light. The result is a significant improvement of the odour situation.

UV light needs like activated carbon a good pre-separation of dust or smoke in order to ensure that its effects are complete. After the UV oxidation state a reaction section is necessary for completing the oxidation process.

UV light tubes are ideally suitable for high exhaust air temperatures from for example frying plants and convince by their long durability of 8000 – 10000 hours.
