HIGH INLET TEMPERATURE AIR COOLING REFRIGERATED AIR DRYER

The front air-cooling pre-cooler and the condenser in the cooling system use the forced ventilation system for cooling, the advantages for air cooling system: easy to install and maintain, little early investment, low operation cost, suitable for the conditions with comfortable environment temperature and good ventilation, especially suitable for the areas free of water or short of water resources. The machine use a high quality fan motor, mostly applied to the low load and movable situations, which are largely influenced by the environment temperature.

EXTERNALLY HEATED PURGE DESICCANT AIR DRYER

According to the principle of PSA and TSA, the moisture in the air will be adsorbed and compressed with the special appetency of the sorbent on the steam. The machine is of two-tower structure. Under PLC control, the two towers run alternately: one tower adsorbs moisture under high pressure while the other desorbs steam using the dry air it produces at low pressure and high temperature, thus keeping the cycle going. This design consumes less purge air than a heatless regenerative dryer, though it does require some electric power to heat the regenerated air.

Inlet oil content≤ 0.01 ppm
Outlet air pressure dew point− 20 ℃ – − 70 ℃
DesiccantActivated aluminum or molecular sieve
Working periods60 – 180 minutes
Inlet temperature0 – 45 ℃

HEATLESS PURGE DESICCANT AIR DRYER

According to the principle of PSA, moisture in the air is adsorbed and compressed by the sorbent’s affinity for steam. The two-tower structure runs alternately under PLC control: one tower adsorbs moisture at high pressure while the other desorbs using previously dried air, maintaining continuous operation. Although this machine consumes some compressed air for regeneration, its overall energy use is much lower than heat-sourced regenerative dryers, making it a widely used solution for air drying today.

particles to 0.01micron (0.003ppm w/w maximum remaining oil content).

AIR TANK

Functions Of Air Tank In Compressed Air System:
To satisfy the increase of compressed air demands and avoid the negative influence of air flow fluctuation on the gas point in the pipeline system. To cool the compressed air, discharge the water in compressed air, reduce the load of air dryer, and save more energy. To reduce the unloading time of air compressor and reduce the energy consumption of the air compressor.
