DESIGN FEATURES

Long Device Life

With the Whisperjet, steam impinges upon itself to reduce pressure as it flows through a series of multi-pressure reduction stages. Pressure drop does not rely solely on a tortuous path like most pressure letdown devices; thus, there is virtually no part erosion, which you would commonly see in orifice plates or other pressure letdown devices.

Longer System Life

When Whisperjets are used in conjunction with a valve or other system components, the seat life of the valve is substantially increased. When used before a condensor or flash tank, baffle and tank wear are greatly reduced.

Reliable

Whisperjets have been installed in industrial applications around the world for over twenty-five years. They are proven to be rugged and reliable in high-pressure environments.

Reduced Noise

Each section has four to six orifices around its perimeter. The orifices discharge inwardly, which reduces the steam pressure without causing component wear. Pressure is reduced in stages, which prevents a critical pressure drop. Each stage is progressively larger, allowing the steam to expand. The orifices are sized to keep the flow of steam below critical velocity. This gives the advantage of reduced noise.

Economical

Due to their simple, practical design and operation, Whisperjets are low-cost solutions to velocity problems.

Flexible

The number of Whisperjet stages may be varied for almost any flow requirement. Our engineering department will work with you to custom-specify a Whisperjet to meet your needs.
