How to reduce compressed air consumption in drying and blow-off applications
You probably don't spend much time thinking about all the applications in your plant that require compressed air. But compressed air is a costly utility that can easily account for 1/3 of a plant's total electricity usage.
Yet, compressed air is often viewed as a fixed cost and overlooked when process improvements are considered. If that's the case in your plant, it may be time to revisit that approach. You may be able to save tens of thousands or even hundreds of thousands of dollars annually by significantly reducing compressed air consumption in your drying and blow-off operations.
In addition to dramatically reducing air consumption, other positive effects can result from making some changes:
- Reduced noise
- Improved worker safety
- More precise, repeatable drying and blow-off
So, what types of changes should you consider? If you're using open pipes, pipes with drilled holes or pipes with slits are for drying and blow-off, you should definitely consider air nozzles or air knife packages. While open pipe systems are fast, easy and inexpensive to manufacture, the drawbacks of using open pipes are many:
- Very high air and electrical consumption.
- High noise — compliance with OSHA noise level requirements can be a problem.
- Worker safety can be compromised. High noise can result in hearing loss and injury can result if a worker accidentally blocks the opening in the pipe.
