BEKO EVERDRY Heat Regenerative Adsorption Dryer -The solutions+results on all application

BEKO EVERDRY heat regenerative adsorption dryers, which are designed for large volume compressed air flows from 600 m³/hr up to 20,000 m³/hr; from 4 barg to 10 barg.  EVERDRY is synonymous with market leader in custom-designed plant engineering using high performance technology. 

Also known as heat regenerated dryer with long adsorption cycle up to 12 hours or more, EverAir GmbH a company of the BEKO Group, with their vast experience have formulated heat regenerative dryers suited for all application and pressure dew point demand.  With our clients demand, Everdry have the complete drying package  - From the basic FRP Blower Purge Dryer, FRA/FRP Zero Purge Dryer, to the advanced FRL Closed Loop Zero Purge Dryer. 

EverAir continue on with Zero Energy Heat of Compression Partial Stream and Full Stream dryer, no heater or blower is needed, using energy recovery system to produce clean and yet dry compressed air.

Heat regenerative adsorption dryers have almost similar cycle operation as Heatless absorption dryers.  They have Adsorption phase, desorption(heating) phase, standby phase; due to heater being used , additional cooling phase is added to lower the desiccant core temperature prior to standby phase.   Heat regenerative dryers use higher durability desiccants with high crush strength which are able to adsorb more moisture.

Heatless desiccant dryer commonly available in market: Dryer volume: 3,400 m³/hr, Compressed air cost: RM0.05/m³, pressure dew point -40°C, air loss 20%, annual operation hour: 4,000 hours

Heatless desiccant dryer: 3,400 m³/hr x RM 0.05/m³ x 0.2 x 4,000 hr/yr = RM136,000.00

Everdry Heat Regenerative Dryer Key Advantages                                              

1.  Saves huge energy cost as compared to Heatless absorption dryer

2.  Longer valves life

3.  More stable and consistent pressure dew point output

4.  Low pressure drop across the entire dryer

FRL - CLOSED LOOP ZERO PURGE DRYER/ ZERO AIR LOSS DRYER                            

Key advantages: Closed Loop Cooling Phase

Inside the B2 desorption(heating) vessel exists hot but dry air.  Using water cooled stainless steel heat exchanger, the hot and dry air is being cooled down while absorbing heat from the hot(about 100°C) desiccant vessel.  The air act as cooling agent until the vessel is completely cool enough for next adsorption phase.

No ambient air is used for cooling, therefore, no pressure dew point 'spike' exists on next switch over.

Blower zero purge dryer with long cycle operation of 6 hours and above.

Key advantages: Fast payback, Zero purge, energy saving on compressed air system.

FRC - BLOWER ZERO PURGE DRYER/ ZERO AIR LOSS DRYER                                    

Blower zero purge dryer with long cycle operation of 6 hours and above.

Key advantages: Fast payback, Zero purge, energy saving on compressed air system.

Not suitable for tropicalized countries.

HOC-P - HEAT OF COMPRESSION PARTIAL STREAM / ZERO AIR LOSS DRYER          

Key advantages:

Heat of compression/Zero air Loss dryer does not use heater energy, suitable for 2-stage oil-free compressors.

The dryer install at  the compressor's 1st compression stage(Low Pressure), uses the hot compressed air heat(150°C and above) to regenerate the saturated desiccant vessel. The cool compressed air is then proceed to be dried by another desiccant vessel.  The end product is -40°C without using any extra energy.

Partial Stream is a fixed ratio of 1st compression stage(Low Pressure) AND final output(High Pressure after aftercooler) being flowed into the Heat of Compression dryer.

HOC-F - HEAT OF COMPRESSION FULL STREAM / ZERO AIR LOSS DRYER                 

Key advantages:

Heat of compression/Zero air Loss dryer does not use heater energy, suitable for 2-stage oil-free compressors.

The dryer install at  the compressor's 1st compression stage, uses the hot compressed air heat(150°C and above) to regenerate the saturated desiccant vessel. The cool compressed air is then proceed to be dried by another desiccant vessel.  The end product is -40°C without using any extra energy.

Full Stream implies that 100% of 1st stage compression(Low Pressure) OR final output(High Pressure after aftercooler) being flowed into the Heat of Compression dryer.
