Air Dryers by EL-AV Compressors
Air dryers play an important and central role in the compressed air system – to isolate moisture from the compressed air before it enters the plant piping. There are different levels of air drying, marked in accordance with the dew point. In Israel, measurements are made on the Celsius scale.
EL-AV Compressors uses two main air dryer technologies: refrigeration dryers and chemical adsorption dryers, that provide the customer with dry air at a dew point starting from +3°C to -70°C. The level of air required is determined by the machines or industry for which the air system is designated. Our air dryers are manufactured at the highest level of quality to provide customers with dry, high-quality air and peace of mind.
Refrigeration dryers
All of EL-AV Compressors’ refrigeration dryers operate with a refrigeration compressor, using an environmentally friendly refrigerant. The working principle of refrigeration dryers is to cool the compressed air taken into it, condense the vapor to a liquid state and then, with an electric device, drain it from the system. In essence, the refrigeration system transmits gas through the heat exchanger while simultaneously transmitting “hot” compressed air; thus, the condensation or drying stage is performed. The advantage of this technology is its energy efficiency, maintaining a uniform dew points of +3°C, and low maintenance costs.
All dryers manufactured by EL-AV Compressors use heat exchangers made from high-quality aluminum, with high durability over time.
Chemical adsorption dryers
EL-AV Compressors adsorption dryers operate according to the “dual tower” method. In this method there are two tanks filled with adsorption material operating cyclically. In each cycle, moist air is transmitted into one of the tanks, passing through the adsorption material and exiting on the other side dry to a level of up to -70°C dew point. After the cycle has ended, the air is transmitted through the dry tank, and some of the dry air returns to the wet tank in order to dry it and prepare it for the next cycle. The advantage of this method: A much lower dew point can be achieved compared to the +3°C of standard refrigeration dryers.
EL-AV Compressors adsorption dryers employ advanced controls with an advanced valve arrangement and high level of adsorption material to achieve excellent results of air quality, maintain high energy efficiency, and achieve a reliable, high-quality product to serve the customer for many years.
