Heatless Air Dryers SERIES: ADZORB & ADZORB PLUS Capacity : 40 cfm to 10,000 cfm Working Pressure : 4.5 to 70 bar(g) Need of Compressed Heatless Air Dryer Compressed air leaving the compressor contains considerable quantities of water vapour, oil particles. If the untreated air is supplied to distribution lines, then the moisture would condense to liquid water as it gets cooled. The condensed water is a major cause of downtime in compressed air systems as it causes rust, pitting, blockages and freeze ups, which result in component failure and product rejection. The only way to prevent condensation of water in air lines is to lower the dew point of the air in the system. It is less expensive to own and operate an air dryer than to live with the problems. Adzorb Heatless Air dryer Operation Coalescing filters of 5 micron and 0.01 micron remove bulk moisture and liquid oil from the compressed air. This pre-treated air diffuses to the bottom of the adsorber (T1) and passes through the desiccant bed which adsorbs moisture and dries the air. Dry air leaves the adsorber (T1) and passes through 1 micron dust filter. Thus dry, filtered compressed air is available for precise operation. The desiccant can adsorb only certain quantity of moisture and will reach equilibrium after certain time. It can no longer dries the air to the required dew point and hence it should be regenerated to keep the process continuous. To regenerate the first adsorber (T1), partial quantity of dry air coming out of second adsorber (T2) is diverted to first adsorber (T1). This dry air expands to atmospheric pressure and becomes subsaturated. This subsaturated dry air purges out all moisture from the first adsorber (T1) and makes it ready for next adsorption process. All these operations are perfectly performed by valves and controller. We are dealing Elgi, Trident Dryer , GEM Dryer and Summits Hygronics dryer, Atlas Copco, IR, Kaeser,

Compressed air leaving the compressor contains considerable quantities of water vapour, oil & particles. If the untreated air is supplied to distribution lines, then the moisture would condense to liquid water as it gets cooled. The condensed water is a major cause of downtime in compressed air systems as it causes rust, pitting, blockages and freeze ups, which result in component failure and product rejection. The only way to prevent condensation of water in air lines is to dry the compressed air thereby lowering the dew point of the air. One of the most economical method to dry the compressed air is by cooling it to the least possible temperature and separate the condensate. Elix Refrigeration air dryer does this job in the most efficient way. Working principle of Refrigeration air dryer When we cool compressed air, water vapour present in the compressed air is condensed to liquid water and can safely be separated. Summits Elix series refrigeration air dryer works based on this principle. Elix heat exchanger is composed of 3 sections namely Pre-cooler (Air to air heat exchanger), Evaporator (Air to refrigerant heat exchanger) & Moisture separator. Wet compressed air (Red color) enters the pre-cooler section where heat transfer takes place between incoming wet compressed air and outgoing dry compressed air. Wet air is pre-cooled by outgoing dry cool air. At the evaporator section air is further cooled to the dew point of 3°C. Water vapour is condensed and separated at moisture separator and drained via drain port. Dry cool air (Green color) is passed back via precooler to pre-cool the incoming wet air. Thus Dry air at normal temperature is available for its use.

55-250kW DIRECT ROTARY SCREW AIR COMPRESSORS Our most energy-efficient air compressor to date, the NxHE Series compressors use patented two-stage airend technology to provide efficient operation with outstanding durability and offer the lowest life-cycle cost of any compressor on the market. Description TWO-STAGE COMPRESSION: SETTING THE STANDARD FOR ENERGY EFFICIENCY Compared to single-stage rotary screw compressors, a two-stage is much closer to isothermal compression. This is achieved by injection of fresh oil between the stages which reduces the inlet temperature to the second stage. This lower inlet temperature increases efficiency by reducing the compression ratio between the stages. In addition, leakage between the rotor seals is significantly reduced resulting in outstanding volumetric efficiency. Two-stage air compressors are closer to the ideal isothermal compression: • Reduced leakage increases volumetric efficiency • Saves 10-15% of energy compared to single-stage compressors • Increases flow 10-15% compared to single-stage compressors • Lower pressure differential increases efficiency and reliability • Low heat load • Easy maintenance and service • Lowest life-cycle cost of any compressor on the market eCOOL® TECHNOLOGY The ultimate in system protection and reliability • Protects critical components from compressor-generated heat • Compartmentalized air flow design and oversized aftercooler • Extends component life and reduces downtime ENERGY EFFICIENT TWO-STAGE AIREND Energy-saving and Eco-friendly • Patented airend design integrates the first and second stage rotors into one airend • Oil is injected between the first and second stages to cool the air and optimize efficiency • Splitting the compression cycle into Two-stages reduces the axial and thrust loading to which improves service life of airend and bearings • Two-stage compression significantly reduces noise EFFECTIVELY INTEGRATED OVERALL DESIGN Designed for low cost of ownership, easy service & little down time • Safe, efficient air filter system • Independent bearing lubrication • High efficiency, easy-to-maintain oil separator • IE3 high efficiency motor • End face sealed to prevent leakage • Connections utilize o-ring face seals for leak–free performance • Asbestos-free gaskets protect operator health
