Some individuals refer to compressed air as their fourth utility after gas, water and electricity, mainly due to its usage of hefty energy. For the majority of compressed air systems, more than 70 per cent of the electricity running the system winds up as wasted heat.
Regardless of their inefficiency, compressed air piping systems are crucial in several environments, including healthcare and manufacturing. This is because it brings force, along with steam systems, without the chances of kindling fire. Below are three hacks to enhance the efficiency of compressed air systems that are pressurised to 100-psi or more.
Industry experts recommend primarily fixing compressed air leaks, which needs quite an affordable investment with a fast payback. Aside from making the system more efficient, implementing leak repairs also helps you save on your energy bill.
Reduce the pressure
Keep in mind that more pressure requires more energy, and preventing unreasonable high pressure could save energy. The sad fact is most factories produce 100 psi air when they only require 40 psi at the application.
Unquestionably, some more pressure on the compressor is needed to direct the air to the destination. Generally, though, the exit pressure of the compressor must only be 10 per cent greater compared to the primary distribution line close to the last destination. The rule of thumb here is for each two psi that you lower, you save one per cent of the energy that your compressor is using whenever it is running in the 100-psi range.
Moreover, as long as you can get back the wasted heat off the air compressor, then you will be able to save nearly 2,500 BTU for every horsepower. This is still the case if you only recover 1,500 BTU for every horsepower at 100 HP, you still have 150,000 BTU for every hour.
