Multistage ejectors with condensers
SCAM MULTI-STAGE EJECTORS with condensers may be of two or multistage type. Condensers placed between one stage and the other are meant to condensate the steam coming from the previous stage in order to reduce the quantity of intaken fluid and, therefore, the motive steam consumption of the following stage.
The number of stages (max. 5-6) is stated according to the required operating performances.

Applications
There are many diversified applications of SCAM ejectors; the original one, which is the extraction of incondensable substances from the steam condensers, was followed by many others, mainly in the chemical and petrochemical fields, thanks to the easy operation and maintenance of these equipment.
One of the most interesting fields of application of SCAM ejectors is the vacuum cooling branch: water or an aqueous solution brought to a suitable temperature under vacuum, literally cools itself as the result of evaporation.
