A typical Ejector contains a single-channel, with one nozzle and one diffuser. With a multi-channel Ejector, the arrangement is instead split into multiple, separate channels. These channels remain housed inside a single, common Ejector body. So, from the outside, multi-channel Ejectors look fairly similar to regular Ejectors, with 3 connections (motive, suction and discharge), but are, importantly, significantly shorter.
The primary reason for selecting a multi-channel Ejector over a single-channel Ejector is size.
Multi-channel Ejectors are significantly shorter in over-all length when compared to an equivalent single-channel Ejector. This provides a number of key benefits;
- Can be installed into facilities (offshore etc) with restricted space
- One of the individual channels can be performance tested in Transvac’s test facility
- Easier to install
- Less awkward for shipping and handling
- Retains Universal Design for future flexibility
