Refrigeration Compressed Air Dryers for volume flows from 20 to 850 m³/h 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 moisture 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 controlled by a hot gas bypass which assures the dryer functionabilty for partial loads, too. volume flow* volume flow* pressure drop power supply power consumption cooling air requirement air connection type m³/h m³/min bar V/Ph/Hz kw m³/h BSP kg DC 0020 AB 20 0.33 0.03 230/1/50-60 0.16 200 1/2 26 DC 0035 AB 35 0.58 0.06 230/1/50-60 0.18 200 1/2" 27 DC 0050 AB 50 0.83 0.09 230/1/50-60 0.22 300 1/2" 29 DC 0065 AB 65 1.08 0.11 230/1/50-60 0.22 300 1/2" 31 DC 0085 AB 85 1.42 0.15 230/1/50-60 0.30 300 1/2" 32 DC 0105 AB 105 1.75 0.17 230/1/50-60 0.30 300 1" 33 DC 0125 AB 125 2.08 0.22 230/1/50 0.46 300 1" 34 weight DC 0150 AB 150 2.50 0.19 230/1/50 0.47 300 1 1/4 55 DC 0180 AB 180 3.00 0.22 230/1/50 0.72 380 1 1/4 56 DC 0225 AB 225 3.75 0.23 230/1/50 0.80 380 1 1/4 57 DC 0300 AB 300 5.00 0.19 230/1/50 0.70 450 1 1/2 68 DC 0360 AB 360 6.00 0.26 230/1/50 0.76 450 1 1/2 74 DC 0450 AB 450 7.50 0.04 230/1/50 0.80 450 2 116 DC 0550 AB 550 9.17 0.16 230/1/50 1.10 1900 2 120 DC 0650 AB 650 10.83 0.23 230/1/50 1.52 1900 2 121 DC 0750 AB 750 12.50 0.10 230/1/50 1.55 2500 2 155 DC 0850 AB 850 14.17 0.14 230/1/50 1.60 3300 2 165 * according to ISO 7183 Novus Technik Pte Ltd 8 Eu Tong Sen St, Office 2 @ The Central #17 83 Singapore 059818 Phone: +65 6838 5139 Fax: +65 6491 6501 Email: comm@novus.com.sg Web: www.novus.com.sg Subject to change 03/2010

Asia Pacific Version Refrigerated Air Dryers VARIABLE SPEED DRIVE* ASCC00 - ASV28P TAN Refrigeration Compressed Air Dryer for medium and big volume flows Operating mode Additional advantages of the new dryer generation: Compressed air is fed into the dryer and being precooled in the air-to-air heat exchanger by the outgoing cold compressed 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 discharged automatically. Finally, the cold discharged air is being rewarmed by the incoming compressed air. This saves 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 compressor 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 therefore 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 controlled by the Variopulse controller via a frequency converter. 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. 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 the following parameters: Current pressure dew point Operation mode Normal/Summer/Autom.

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, pressure in the refrigeration cycle, ambient temperature as well as dryer specific parameters are processed and the current operation conditions are calculated so that a demandoriented control of the refrigeration system is possible by using the suction pressure control or a frequency converter. This leads to considerable energy savings of up to 90 % related to the nominal power consumption. The pulsating measuring (serveral times per second) and the aluminium 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 Energy saving potential 24% Operation and Maintenance 14% Installation 2% Energy 40-75% Amortization 20% This diagram illustrates the very large share of energy costs related to the initial costs (depreciation). This means that the energy costs normally exceed the initial costs considerably during the life cycle of a product of a refrigeration compressed air dryer. Next to the cost reduction, this energy saving also stands for environment protection because with every additionally consumed kwh the environment is polluted with 0,56 kg CO 2 which in turn increases the global warming.
