Refrigerated air dryer ETM DM series

The ETM DM are compressed air treatment modular units that can be connected to each other via MASTER/SLAVE logic. Each unit integrates a high-efficiency compact aluminium exchanger, a separation system and a condensate drain. In the MASTER configuration, the ETM DM modules include an electronic control unit that ensures correct operation. Installable anywhere The upgrading of large systems for the production of compressed air is often problematic and very expensive due to the lack of available space in equipment rooms. ETM DM modules perfectly solve this problem because, thanks to their compact dimensions and the possibility of being connected to a chiller located outside of the compressor room, they can also be easily integrated within existing systems. Maximum reliability level Very often large systems are not designed according to redundancy criteria as the installation of multiple dryers in stand-by with the corresponding piping take up valuable space. During maintenance these systems must therefore be put offline causing costly system downtime. The modular approach of the ETM DM ensures intrinsic redundancy of the critical components and therefore enables the reduction of periods of system downtime. Ultimate energy saving The load profiles of most of the manufacturing industries are highly variable. The flow rates of compressed air to be processed and the process temperatures fluctuate greatly during the day, forcing the dryers to operate at partial load for most of the time.
