Steam Ejectors

Nitech’s steam jet ejector is a simple, highly versatile type of compressor, usually applied to create and maintain vacuum. This type of system has been proven to be a low cost, low maintenance alternative to vacuum pumps.

Steam ejectors function using the principle of convergent / divergent venturi theory. High pressure / low velocity motive fluid is expanded through a nozzle into high velocity / low pressure fluid flow. The molecules collide with process gases and move into the diffuser area where the energy transfer is reversed to achieve compression.

This chart shows the application range of Nitech single and multi-stage ejectors. Proper selection of an ejector involves engineering and manufacturing skills far beyond those implied by it’s low cost. To assure proper operation and maximum efficiency from your ejector installation, take advantage of the engineering talent and know-how available from Nitech.
