Air Purification System

Air Purification System

The ionizing-collecting cells (contaminant collecting elements) are housed in the cabinet on slide rails. They can be removed from the cabinet as required, through the end access door, by sliding them out like drawers. On multi-cell units, all of the electrical connections between cells in a given tier are automatically made through spring plunger connectors.

When installing the cells into the cabinet, observe the directional arrows on the cell end plates. The side of the cell containing the spiked ionizer blades must always be located on the air entering side. The spring plunger connectors, located on one end of each cell, will always face toward the access door on the Ionizer cabinet.

Both the air entering and air leaving side of the cabinet provide locations for filters as specified. These items act as trash screens, provide resistance for even air distribution, and help contain splash back from the integral water wash system.
The Power Supply(s) convert the single phase AC supply to the high voltage DC needed to power the ionizing-collecting cells. Potential of 12 KVDC are required for the ionizer sections and 6.0 KVDC for the collector sections of the cells.

The integral wash system consists of a series of spray nozzles assembly on water wash manifolds. The manifolds are located in the front or back or both front and back of each cell tier. A detergent system is also incorporated into the wash system. The amount of detergent used for washing is readily adjustable, and that amount is dependent upon the type and amount of collected contaminant.

Principle of Operation

The Vianen Air Purification System consist primarily of what is technically known as an electrostatic precipitator. In this type of equipment, all airborne particles, even of microscopic size, are electrically charged (positively) as they pass through a high voltage ionizer. These charged particles are then attracted and adhere to a series of parallel collecting plates, which form the negative elements of an electrostatic field.

The ionizer consists of charged stainless steel spiked blades spaced between grounded electrodes. The collecting section consists of parallel plates arranged so that each alternate plate is charged while the intermediate plates are electrically grounded.
