Compressed air tanks

Air receivers

Air receivers perform vital functions. In many cases, a single tank in the compressor room is sufficient. In larger systems, placing tanks at multiple points within your air system can be a low cost option to improve air system performance and plant operations overall. 

Wet tanks placed after the compressor and before the dryer reduce starts and cycling. This saves power and reduces wear and tear on motors, starters and valves. Wet tanks provide a cooling zone that promotes moisture separation. A properly sized automatic drain will remove liquids and keep the tank volume available for storage. 

Dry tanks placed downstream of dryers and filters will store clean dry air. Under normal conditions, they will have little to no moisture, but a drain is inexpensive insurance. Dry tanks are a good place to attach sensors for system controls. 

In-line tanks placed strategically around the plant can help reduce pressure fluctuations, especially if you have long pipe runs. This can be an inexpensive way to help systems that have outgrown their piping. This happens over time as more capacity is added in the compressor room but piping has not been resized to accommodate more flow. 

Point of use tanks placed at high volume intermittent demand applications ensure proper operation and reduce impact of large flows on other nearby air users. 

Receiver tanks deliver big benefits and require only minor maintenance and periodic inspections. Kaeser’s expert system specialists will help you select the right tanks and find the best installation locations to improve air quality, maintain steady pressure and save energy.
