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.

Air compressors are used in many different applications and provide essential compressed air to many businesses and individuals with different air needs. No matter what your CFM, PSI and HP requirements are, the electronic controller on your air compressor is the motherboard for keeping your unit running as efficiently as possible. It is your eyes into your machine.


The emergency stop, "e-stop", is for true emergency situations only. When hitting the e-stop, all power is halted from the machine and the unload process isn't achieved. The emergency stop button is intended to help with possibly hazardous situations that are developing. Common conditions of having to use the e-stop is the misuse of the equipment in ways that weren’t intended, predictable failures not addressed or failing to consider all the foreseeable uses of the compressor.


Air compressors are helpful for an enormous range of applications such as air filling, packaging, tools, HVAC control, and more! One possible drawback is the amount of electricity they use; air compressors can be a huge drain on energy if used ​inefficiently​. If you are running them too long, allowing leaks to exist, or using the wrong type of compressor, you are wasting ​energy and money​. This article will go over some of the biggest power-wasters and how to
stop/prevent them!
