Global drinks manufacturer cuts air and inefficiencies
When a 40 bar turbo compressor situated within an internationally renowned British-based producer of soft drinks broke down, it was faced with two choices: repair or reconfigure. Choosing the latter, the producer found that the old proverb ‘as one door closes, another opens’ proved true. Founded in the late 1930s by an entrepreneurial chemist, Britvic […]
How can you use compressed air storage to reduce peaks?
A press operation used a pulse of compressed air for cleaning operations for 10 seconds, once every 10 minutes. The compressed air flow to the press during the cleaning was 400 cfm, a quite significant flow, and data logger measurements of the air compressors found that each time the blow happened, a 150-hp compressor would […]

Contributed by Mike Kreklau, Technical Sales at Tsunami Compressed Air Solutions Downtime and inefficiency don’t have to be your production line’s worst enemy. You want shop equipment that comes with no strings attached — no downtime and no maintenance. Maybe that’s a pipe dream, but there are ways to fix many air-related symptoms of an inefficient […]
Compressed air fail: Sensor eye blowing
The operators at a lumber mill were having production problems in two of their machines. Annoyingly, critical sensing eyes were getting blocked by occasional pieces of bark as the logs went by. After enduring this for quite a while the maintenance department finally took matters into their own hands. The plant had a welding department, […]
A look at misfit compressed air tools
Are you still using open ended compressed air blowing? Are these blowers simply controlled by a ball valve? Did you know these tools can turn into dangerous uncontrolled projectiles if accidently dropped when the valve is wide open? They cause noise pollution and present a risk of eye injury when chips of debris are sent […]
How do you measure your compressed air’s air quality?
Many industrial sites measure their compressed air quality, or think they do. When asked to show the dew point of a system with refrigerated air dryers, the compressor operators will typically point to the air dryer display, not knowing that the reading is not really dew point, but the temperature within the air dryer itself. […]
Compressed air fail: Load sharing
A large foundry had four large 200-hp air compressors that were water-cooled and were having overheating problems. The units were capable of inlet modulation control, where the inlet valve of the compressor closes off the intake to control the output flow. Use of this control mode reduces the flow output of the compressors and the […]
Compressed air fail: Dryer overload
A building products company purchased a compressor with 1,520 cfm capacity to help with the increased load after a plant expansion. Various dryer sizes were available, but one sized at 1,600 cfm was selected, rather than choosing the next size up, to save purchase costs. Shortly after installation, the production machine operators started complaining about […]
Compressed air fail: Safety hazard
During a compressed air assessment, a service provider was reviewing the total capacity of the storage receivers for his report. Having adequate capacity helps make the compressors run more efficiently and saves energy. During his checks, he spotted a strange color on one receiver safety valve. On closer inspection, he noticed that the pressure relief […]
The magic of compressed air heat recovery
A facilities manager at a building products plant attended a compressed air efficiency seminar sponsored by his local utility.

He discovered the excellent savings he could […]
Compressed air fail: Pressure drop square function
A building products company was having problems with pressure loss across its main dryers and filters. Data monitoring showed differential pressure reached as high as 18 psi, causing a large sag in plant pressure, which during peak times caused production outages. An investigation revealed that the dryer was low on refrigerant, causing the unit to […]
How much of my electric bill is consumed by air compressors?
By Ron Marshall What is my compressed air’s electric bill percentage? This is a difficult question to answer, because rarely are there any energy meters installed on typical compressed air systems. But there are some hints if we do some research. Years ago, the USDOE did a detailed study of motor systems and found that […]
Compressed air fail: Don’t forget the dryer!
A pump manufacturer implemented a new compressor control strategy that was intended to save energy. The c0mpany had three compressors running — one fixed speed unit and two VSD style units — and found after studying the system they only needed two compressors to feed the load. Savings could be gained by automatically turning a […]
What is the best compressed air adjustment location?
A common question posed to compressed air experts is “What component should I adjust to get my compressed air system running more efficiently”? The common answer is, “You should adjust that thing located between your ears.” Compressed air professionals commonly find poorly maintained and incorrectly adjusted equipment when they visit their customers’ compressor rooms. And […]
Compressed air fail: Regulator size
An industrial component manufacturer had a system of five compressors located in an interconnected system spread between two buildings. The system pressure of the system was constantly running near 120 psi because of some critical high-pressure applications. Most of the production machinery was rated at 90 psi pressure. The facility manager was sure something could […]
