The compressed air is being fed into the dryer and being pre-cooled in the air-to-air heat exchanger by the outgoing cold compressed air.The pre-cooled air then passes through the refrigerant-to-air heat exchanger where it is being further cooled down to the required pressure dew point. The mois-ture in the compressed air condenses out and gathers and discharges automatically. Finally, the cold discharged air is being reheated by the incoming compressed air. This saves energy and prevents any moisture forming beyond the dryer in the compressed air system.The cooling capacity of the refrigeration cycle is being con-trolled by a hot gas bypass which assures the dryer functio-nabilty for partial loads, too.

ASCC00 - ASV28P TANRefrigeration Compressed Air Dryer for medium and big volume flows

Operating mode

Compressed air is fed into the dryer and being precooled in the air-to-air heat exchanger by the outgoing cold com-pressed air. The precooled air then passes through the refrigerant-to-air heat exchanger where it is further cooled to the required pressure dew point. The moisture in the compressed air condenses out and is collected and dis-charged automatically. Finally, the cold discharged air is being rewarmed by the incoming compressed air. This sa-ves energy and prevents any moisture forming beyond the dryer in the compressed air system.

Variopulse: two methods - one purpose: Energy saving

Suction pressure control (ASCC00 - ASCC03)

With partial load, the suction line of the refrigerant com-pressor is closed by a solenoid valve. Because of this, only a partial amount of refrigerant is sucked and compressed by the compressor. The result is reduced load and there-fore reduced power consumption. With lower partial load or zero load, the compressor is switched off completely by the Variopulse controller at times.

Frequency converter control(ASV06P - ASV28P TAN)

The speed of one of the refrigerant compressors is con-trolled by the Variopulse controller via a frequency conver-ter. The other compressors are switched on when required (partial load or full load). This leads to a reduction of up to 90 % of the nominal power consumption.

Additional advantages of the new dryer gene-ration:

• Variopulse-controlling for the whole range as standard• CAN-bus interface• Datatransfer optional• Illuminated multi functional display• Load controlled energy consumption, reduction of up to 90 % of the nominal energy consumption• Level controlled drain UFM-T100• Display is changeable from °C to °F• Max. operation parameter, inlet temp. 70 °C, ambient temp. 50 °C and working pressure 16 bar g for the entire range• Generously sized air-to-air and refrigerant-to-air aluminum heat exchanger with a large power density and generously dimensioned flowchannels• One-component refrigerant R134a, Ozone-depleting factor zero• Compact and easy to install cabinets

The Multi Functional Display shows thefollowing parameters:

• Current pressure dew point• Operation mode Normal/Summer/Autom.• Power consumption related to the total hours of opera-tion• Alarm signal• Alarm history• Maintenance required• Operation hours• Fridge compressor on/off• Current energy consumption

This example of energy saving relates to these basic conditions:Industrial production with one-shift operation, 5 work days per week, stand-by operation during idle periods and an electricity tariff of 8 Eurocent per kWh – the pressure drop is not included in this calculation, it leads to additional ener-gy costs of 40 – 80%The above is only an example and does NOT relate to all site operating conditions. Contact Novus for computation of savings for your site conditions

Variopulse: The intelligent dryer control

This microprocessor based controller is the heart of this dryer generation. Values like cooling temperature, pressu-re in the refrigeration cycle, ambient temperature as well as dryer specific parameters are processed and the cur-rent operation conditions are calculated so that a demand-oriented control of the refrigeration system is possible by using the suction pressure control or a frequency conver-ter. This leads to considerable energy savings of up to 90 % related to the nominal power consumption. The pulsa-ting measuring (serveral times per second) and the alumi-nium heat exchanger’s function as a cold storage enable the system to quickly respond to a load change.

Average cost distribution for compressed air treatment

This diagram illustrates the very large share of energy costs related to the initial costs (depreciation). This me-ans that the energy costs normally exceed the initial costs considerably during the life cycle of a product of a refri-geration compressed air dryer. Next to the cost reduction, this energy saving also stands for environment protec-tion because with every additionally consumed kWh the environment is polluted with 0,56 kg CO2 which in turn increases the global warming.
