The Hidden Danger of Untreated Air
When the air that surrounds us is compressed, its vapor and particle concentration increases dramatically. The compression process causes the oil and water vapor to condense into droplets, and then mix with the high concentration of particles. The resulting mixture is an abrasive oily sludge that in many cases is also acidic. Without air treatment, much of this corrosive sludge will enter the compressed air system, corroding the pipe work, damaging pneumatic tools and equipment as well as potentially compromising final product duality.
The Simple Solution for a Costly Problem
Our refrigerated air dryer offer a reliable, cost effective and simple solution.
To avoid condensation and therefore all chance of corrosion and damage, the compressed air needs to be dried, which is exactly what the HX units are designed to do.
These simple reliable units remove water from the air and the risk from your system, ensuring that your money doesn't just disappear into the air!!
Principles of Refrigerated Air Dryer
The refrigerated air dryer is made up of a compression refrigeration system, composing of four basic components: refrigerant compressor, condenser, heat exchanger, and expansion valve with a sequentially connecting pipe between them forming a closed system. The refrigerant, through continuous circulation in the system undergoes both a change in state as well as heat exchange which takes place between refrigerant and compressed air. The refrigerant (low-temperature and low-pressure), in the heat exchanger is sucked into the cylinder of the compressor. After going through compression both the pressure and temperature of refrigerant vapor increase simultaneously; the high pressure and high temperature refrigerant vapor is compressed into a condenser where heat exchange occurs between the vapor and the cooling air/water in the condenser causing a decrease in temperature of the refrigerant vapor and its subsequent condensation into liquid. This portion of the liquid is then fed to the expansion valve, and through throttling both pressure and temperature becomes low again and is transported into the heat exchanger; here the heat of the compressed air with high pressure and high temperature is absorbed by the refrigerant to raise its both temperature and pressure. Keeping the compressed air under a condition of constant pressure, temperature is forcibly reduced thereby generating lots of saturated vapor. Meanwhile, the refrigerant vapor is absorbed by the refrigerant compressor. Hence the refrigerant in the system undergoes four processes--- compression, condensation, throttling, and evaporation, completing a single circle.
