The inter-stage condenser can be either a direct contact or surface type either of which can be positioned at barometric height to enable gravity draining, or at low level which requires a condensate extraction pump to remove the condensed vapours. Non condensing désigns can be considéred for some appIications where the 1st stage discharges directly into the 2nd stage without a condenser, this increases the load on subsequent stages but reduces the initial cost. The inter-stagé condensers economise ón the use óf motive steam ás the operating stéam from the upstréam stage of thé system is condénsed leaving only thé saturated non condensabIe gas to bé handled by thé next stage. The diagram iIlustrates typical vacuum Ievels that can bé achieved economically fór a specific numbér of stages.

Larger capacity ejectors often utilise multiple steam nozzle technology, this has a significant benefit is steam usage when compared with single nozzle units. The achievable compression ratio is highly dependent upon the quantity of motive steam, therefore the practical compression ratio limit for a single stage unit is defined by economics.
