The Basic Steam Water Spray (BSWS) is a low-cost equipment solution with air overpressure, able to work with all kind of container formats -cans or jars and flexible pouches or thermoformed trays or bowls-.

Top spray is the standard for all cylindrical or square tall containers.

Side spray is optionally available to work with flat or shallow containers like pouches and trays and deliver uniform heating and cooling preventing the “umbrella” under the top spray.

Heating -by direct steam injection- and cooling -by mix and replacement of hot water by cold water- are finely controlled to keep the pressure constant, which is essential to preserve weak package integrity.
