is the process by which the mechanical action of spray, the chemical action of detergent and the temperature are combined to achieve the cleanness.

It can be accomplished at pressure as low as 0.2bar up to 100 bar and more. Anyway, the common pressure used in cabin or in line cleaning spray process with aqueous cleaners is of about 2-3 bar combined with a rather high volume while the use of higher pressure is limited to specific areas.

Spray cleaning is used for the removal of insoluble particles such as dust and chips combined with oil, and allows reduced cleaning time although less aggressive cleaners at lower percentage are normally used.

Higher productivity associated with a high degree of flexibility has made spray cleaning the most popular method in the production cycles of the industry.






Industrial spray washers are mainly based on moving the parts through the spray or moving the spray on or around parts being cleaned.

Static spray is of limited efficiency on large surfaces and its use is limited to specific areas such as blind holes or cavities.
