Higher pressure drop leads to poor system performance. An increase in pressure drop puts more strain on the equipment, which leads to more energy consumption to maintain the desired flow rate and higher electricity bills.
It is commonly known that for every extra 1 bar generated in pressure, we consume almost 7% more of the shaft power. Imagine how much this would cost you more on an average industrial-size air compressor.
Let us explain this using an example as well for better clarification.
Consider you are operating an air compressor unit of 160 kW at extra 1 bar pressure than what the application would require. This will cost more than 11.2 kW to pay for 1 bar extra generated, which is eventually expanded (wasted) using a pressure regulator in the process by the end to match lower application pressure.
In Dubai, industrial power costs 0.45 AED/kWh. According to our hypothetical scenario, this would mean 5.04 AED/Hr (11.2 x 0.45 = 5.04 AED/Hr). So, if you run your air compressor all day, all year long, it would cost you an additional whopping 44,000 AED, which is a lot!
And what if you own and operate multiple compressors? This figure will increase further, and that’s not even the last thing you want.
Suppose your facility requires multiple compressors with high flow rates to carry out heavy-duty applications such as pneumatic material conveying.
In that case, you should consider dedicated low-pressure compressor systems or air blowers as they will function efficiently with better overall reliability and without unnecessarily hiking energy consumption and, therefore, electricity bills. Also benefiting with lesser maintenance intervals.
