Control of Legionella in small evaporative condensers: A risk management approach.

Are your air conditioning units, cooling towers and evaporative condensers up to scratch?

You must tell your council if your commercial site uses a cooling tower or evaporative condenser.

If you have a cooling tower or an evaporative condenser, you must notify your local authority.

Cooling towers and evaporative condensers help to remove excess heat from sites like power stations or chemical plants.

Cooling towers, evaporative condensers, and hot water systems can be growth and distribution sites for Legionella.

For open systems, such as cooling towers, evaporative condensers and spa pools etc, routine testing should be carried out at least quarterly.

The most common sources of Legionella bacteria are cooling towers, evaporative condensers, hot water services, humidifiers and spa baths.

Cooling Towers all premises where cooling towers and evaporative condensers are situated must register with the council.

They may also be found in purpose-built water systems such as cooling towers, evaporative condensers, hot and cold water systems and spa pools.

Our "making" has included freezers, evaporative condensers, ball valves, chillers, chemical blend refrigerants and electronic controllers.

It was fitted with a rotary evaporative condenser, in which the steam was condensed by passing it through a rotating set of tubes.

Evaporative condensers may be cost-effective in drier climates, but the added maintenance may make them unattractive in other climates.Display case shields.

This safety bulletin draws attention to key aspects of the proper management of the risks from legionella in water systems other than cooling towers and evaporative condensers.

Other potential drawbacks are that the savings from water cooling decrease in humid climates and that evaporative condensers require more maintenance than air-cooled condensers.Economizers.

The leaflet is aimed at employers who manage premises with hot/cold water services and/or cooling systems (eg cooling towers and evaporative condensers).

Evaporative Condenser Type NRV capacity 225 to 3143 kW over 50 sizes available with or without desuperheater section.

Air inlets are potential sources of entry of contaminated droplets from the drift of cooling towers and evaporative condensers sited on nearby roof-tops.

Reservoirs in hospitals have included cooling towers, evaporative condensers, locally produced distilled water, heated potable water systems, and heating and air-conditioning systems(36,45,77,78).

Most condensers in grocery stores are air-cooled, but it is technically possible to use evaporative condensers, in which water is sprayed over the condensing coils, instead.

Evaporative - While these remain the least popular choice, evaporative condensers can be used inside or outside of a building and under typical conditions, operate at a low condensing temperature.

"As they are commonly found in environmental sources they may also be found in purpose built water systems such as cooling towers, evaporative condensers and whirlpool spas. "

An evaporative condenser cools the refrigerant vapor by using heat exchange between the evaporator pipes and the evaporated water which is sprayed on the surface of the pipes.

The disease, a respiratory ailment that is fatal in about 15 percent of reported cases, is spread by bacteria that are in devices like cooling towers and evaporative condensers.

Evaporative condensers are more energy efficient, but they do have a notable disadvantage: They require a water supply, which often means increased maintenance due to freezing, clogging, and mineral buildup.
