What can I do to lower the energy cost of my air dryer?

My use multiple air dryers in my facility, and they are causing the energy cost to be high. What can I do to make my air treatment system more energy-efficient?

Pneumatech cycling dryers are energy efficient and are the most commonly used dryer to save on energy and maintenance costs. Cycling dryers are ultimate energy savers. The energy consumption in a cycling dryer will flucuate according to moisture load and flow rate in the compressed air system. Pneumatech's cycling dryers use a Cycle Saver algorithm that starts and stops the dryer to save energy while keeping the relative humidity of the compressed air below 50% to prevent the formation of liquid water. A hot gas bypass valve is used to prevent ice from forming in the dryer during periods of low flow along with an intelligent shutdown feature in the event of freezing ambient temperatures.


For a facility that uses a dryer throughout the day, but may have small lull periods, a cycling dryer is the ideal solution. If your facility is in need of an energy-efficient drying solution and constantly uses compressed air to operate, a cycling dryer is needed. Pneumatech offers durable and reliable cycling (and non-cycling) dryers in various sizes to accomodate the need of any industry.

Just like any other equipment, a compressed air installation also requires the necessary maintenance work during its entire lifespan. Even though maintenance costs are only about 5 to 10% of a machine's annual operating costs, failure to budget for maintenance can have potentially disastrous consequences.


The air dyer is one of the most ignored cooler in the system. A dirty condenser will cause water in the lines, or worse it will cause complete dryer failure.


Using nitrogen is not about fully replacing CO2, but it can reduce their consumption of CO2 by close to 70%. Using nitrogen is about sustainability. Creating your own nitrogen is easy and will reduce the use of a greenhouse gas, which is better for the environment. It will also save you money as early as month one adding that savings to your bottom line.


A question that is occasionally asked by our customers to Ash Air is 'what is the cost of compressed air?'  This article looks at the product costs involved with compressed air, as well as minimising the energy cost of compressors and cost allocation. When looking at these factors, we need to realise what causes dropped efficiency of your compressor, leading to increased costs of compressed air.
