ETM DM

Compressed air treatment modules

Flow rates 30 – 540 m³/min

ETM DM is MTA’s modular air treatment modules for big capacity systems.
The ETM DM are compressed air treatment modular devices that can communicate with one another using MASTER/SLAVE logic. Each unit includes a high-efficiency compact aluminium exchanger, a separation system, and a condensate drain. In the MASTER configuration, the ETM DM modules feature an electronic control unit to assure proper operation.

Description

Installable anyplace.
Large systems for compressed air production are sometimes difficult and expensive to upgrade due to a lack of available space in equipment rooms. ETM DM modules properly solve this problem since, due to their compact size and ability to be connected to a chiller located outside of the compressor room, they can be readily integrated into existing systems.

Maximum dependability level
Large systems are frequently not designed with redundancy criteria in mind, as installing additional dryers in standby mode with the necessary piping takes up significant space. These systems must be turned off during maintenance, resulting in significant system downtime. The modular approach of the ETM DM ensures intrinsic redundancy of important components, allowing for the reduction of system downtime.

Ultimate energy savings
The load profiles of most manufacturing businesses are extremely varied. The flow rates of compressed air to be processed and the process temperatures fluctuate dramatically during the day, causing the dryers to run at partial load for the majority of the time. The system, which consists of one or more ETM DM modules coupled to a TAEevo chiller, is equivalent to a thermal mass energy saving dryer since it can adapt its energy consumption to the actual requirement for incoming compressed air, resulting in the highest level of energy savings.

Adaptable to all needs.
It is possible to select from a variety of chiller + drying module combinations by sizing the system to achieve appropriate pressure loss without impacting the amount of electrical power absorbed, hence boosting the system’s redundancy and safety.

Technical specifications:

  1. Extremely resilient 2-in-1 heat exchanger consisting of an air-air heat exchanger, an air-glycol water exchanger optimized for countercurrent exchange, and a high efficiency demister separator.

  2. Microprocessor control and monitoring of energy savings are standard on MASTER modules.

  3. Dynamic dew-point DDF energy-saving feature with ambient temperature “tracking logic” (ambient sensor DDF kit required);

  4. Liquid chiller remote ON/OFF control.

  5. Safety method to protect the condensate from freezing.

  6. Flanged manifold kit (for connecting two or three MASTER/SLAVE modules);

  7. The hydraulic connection kit has a maximum distance of 5/10 m and includes an RS485 Modbus kit.
