Application of AIR Washer

Application of AIR Washer Points : application of air washer Air washer air primarily employed in industrial air conditioning applications the use of sprays per minute humidification, dehumidification or evaporative cooling, as required. In addition, sprays enable a degree of humidity control not possible with coil alone.

Washer equipment is effective in the removal of certain types of odors and dirt from the air. In applications where coils could become clogged with air airborne solid particles, washers require a minimum of maintenance. This flexibility of function is obtained at relatively low installed cost of equipment per unit of air delivery. A large air capacity is realized from equipment of low weight.

This type of equipment is however, opens hydraulically and thus presents problems in piping design and system balancing. Since the (low of air and water through the apparatus is parallel and since a gravity return of water is usually employed in a dehumidifier application, pipe sizes tend to be larger in an open system and the piping system and insulation more expensive.

The spraying of water at high pressures such are required in washer equipment produces a noise level high enough to be objectionable under some circumstances. Sound treatment is not usually required on equipment serving manufacturing area or areas of high ambient sound levels. For more critical applications the need for sound absorption should be investigated.

The unitary spray washer requires considerably less space than a central station type and requires no special apparatus room. It is more flexible in meeting the necessities of plant layout change and is more adoptable to zoning. The salvages valve is high and the operating weight low:

The central station washer installation results in lower fan noise levels and lower fan operation costs. Since central station washers are usually fewer in number and more centrally located than unitary washers they require less piping when used as de-humidifiers for a given installation.

Central station washers may be obtained for air deliveries of 2000 o 36000 cfm unitary spray washers are available in the delivery range of 78000 to 17000 cfm.
