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.
