What is a Cycling Refrigerated Dryer?

Refrigerated dryers are the most common type of air treatment dryer used in multiple applications from automotive shops to manufacturing facilities. Refrigerated dryers come in both cycling and non-cycling variants, but what exactly is a cycling refrigerated dryer?

Cycling Dryers

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.

Non-Cycling Dryers

A non-cycling dryer will run continuously, reardless of the compressed air flow rate or humidity/moisture in the air. These units also use a hot gas bypass valve to regulate the flow of refrigerant, but it will not reduce the energy consumption of the dryer. These dryers have a lower initial cost than cycling dryers and are ideal for facilities who are not constantly using compressed air.

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. You can browse Pneumatech's refrigerated dryers HERE.
