RA Series adsorption-type dryer
1. RA Series heatless regenerable adsorption-type dryer
Technical features:
Superb machine canister design:
To ensure 4.8 seconds contact time of alumina and enable it to dry the coming saturated air to needed dewpoint.
30% excessive dessicant for compensating the natural aging of dessicant so as to make sure it runs at the best condition always.
Adopts large diffuser:
To guarantee that air flow passes dessicant uniformly.
Reliable control system:
Adjustable on site: 10min cycle time(-40°C dewpoint, inlet Temp. 38°C) or 4min cycle time(-70°C dewpoint, inlet Temp. 38°C). Reliable and durable airflow control valveuses advanced electromagnetic shut-off valve.
Easy operation:
Power on/off switch, cycle mode adjusting, indicating lamps for working and regenerating states.

2. RA Series slight-heat regenrable adsorption dryer
Stabel outlet pressure dewpoint(-40°C)
Reasonbale volume of canister bedding make sure that dessicant has enough contact time with air.
30% excessive dessicant for compensating the natural aging of dessicant so as to make sure it runs at the best condition always.
large diffuser guarantees that air flow passes dessicant uniformly.
Min. regenerating gas consumption(3-7%)
The diameter and height of adsorption tower have been through repeated reasoning and calculation. Reasonable tower design realizes min. regenerating gas consumption and 98% of adsorption heat could be accumulated inside, which maintains the temperature of clean air during the process of regeneration, enables max. moisture removing of air and least air consumption.
Drying gasflow is opposite to the flow of regenerating gas so that the humid air wastes no energy when passing and being dried by dessicant.
Automatic adjusting the air consumption for regeneration as per the inlet load changes so that energy-saving is possible.
Long service life of dessicant
The suitable size of adsorption tower prevents dessciant from floating or pulverization because of the fast speed of air that passes it bedding.
Slow and sufficient pressurizing in regenerating tower protects its bedding from shifting, dessicant from damage and removes pressure fluctuation from the sinking airflow.
The uprising airflow during drying process makes water drops and heavy-polluted granules separated from airflow before entering tower and discharged when the pressure of tower drops.
Most suitable tower size
Ideal capacity of dessicant ensures sufficient contact time and right outlet pressure dewpoint. Excessive dessicant compensates the aged.
High-efficiency and suitable-size enable tower to save heat generated during adsorption so that max. air cleaning and min. regenerating air consumption are realized.
Easy operation
All instruments such as pressure gauges, regenerating gas flowmeter, switch buttons and working state indicating lamps as well as control panel, are assembled in the front of towers with suitable position and height to ground, which is an ideal design for the convenience of operation.
Convenient maintenance
Independent dessicant filling hole and discharging hole, convenient for dessicant replacement and cleaning of diffuser and filtration mesh.
Precise control over the capacity of regenerating gas
Regenerating gas control valve can be precisely adjusted. Airflow always passes it from one direction so as to ensure stable flow. The regenerating gas flow control valve and pore plate can display the capacity of regenerating gas.
Reliable&durable Italian inlet discharge butterfly valve with Min. torque and ideal seals
Intelligent computer control
A CPU supervises all key running conditions and display running state and faults. It controls the running and operation sequence of gas inlet, regenerating valve and heater. Faults will lead to automatic alarm. Remote control port is optional.
