DRYPOINT® M eco control
Intelligent membrane dryer for energy-efficient compressed air drying
The DRYPOINT® M eco control is a state-of-the-art, electronically controlled membrane dryer for reliable drying of compressed air in industrial applications. It was developed specifically for companies with the highest requirements for compressed air quality, process reliability and energy efficiency.
Thanks to its intelligent control, the dryer automatically adapts to changing operating conditions and ensures a stable pressure dew point at all times. This not only optimises the compressed air quality but also significantly reduces energy consumption.
Compared with conventional membrane dryers, the DRYPOINT® M eco control offers considerably greater flexibility, as both constant and dynamic drying strategies are possible. This makes the system suitable both for continuous operation and for applications with fluctuating compressed air demand.
Operating pressure
4 to 10 bar
Pressure dew point

Intuitive operation and simple system integration
The DRYPOINT® M eco control has been consistently designed for ease of use. All parameters can be easily configured and monitored via the integrated control panel. The current operating status is visualised by clear LED signals, so that the system status can be seen at a glance at any time.
The system also has an analogue interface and a data transfer interface that enables clear performance evaluation and presentation – for example in combination with the METPOINT BDL data logger. This allows the membrane dryer to be integrated easily into existing control and monitoring systems – for example for energy analysis, maintenance planning or process optimisation.
Optionally, a volt-free contact can be used to forward status messages or alarms to higher-level systems.

Flexibility through two intelligent operating modes

The DRYPOINT® M eco control offers two precisely adjustable operating modes that allow the degree of drying to be matched exactly to each application:
Constant Mode – Constant pressure dew point
In Constant Mode, a fixed outlet pressure dew point is defined. It remains constant even when the pressure, flow rate or temperature of the incoming compressed air changes. This ensures consistently high compressed air quality – ideal for sensitive production processes, measuring systems or laboratory applications.
This mode is particularly suitable for applications in which a precisely defined freedom from moisture is essential and no fluctuations whatsoever can be tolerated.
Dynamic Mode – dynamic adjustment to the compressed air temperature
In Dynamic Mode, the pressure dew point is controlled automatically at a defined temperature difference from the current compressed air temperature. The dryer thus responds flexibly to changing ambient and process conditions.
The result: only as much energy is used as is actually needed to achieve the required compressed air quality. This mode is particularly efficient with fluctuating loads, intermittent operation or changing ambient temperatures.

Frequently asked questions
What is the DRYPOINT M eco control?
An electronically controlled membrane dryer for drying compressed air in industrial applications. It adapts automatically to changing operating conditions and keeps the pressure dew point stable.
Which operating modes are available?
In Constant Mode, a fixed outlet pressure dew point remains constant even with fluctuating pressure, flow rate or temperature. In Dynamic Mode, the pressure dew point is controlled at a fixed difference from the current compressed air temperature.
When does each mode make sense?
Constant Mode is suitable for sensitive processes, measuring systems or laboratory applications with no tolerance for fluctuations. Dynamic Mode is particularly efficient with fluctuating loads, intermittent operation or changing ambient temperatures.
Which pressure dew points can be set?
For the outlet, values from +10 °C to −26 °C are available. For the difference from the compressed air temperature, 10 to 55 K can be set.
In which pressure range does the dryer operate?
At an operating pressure of 4 to 10 bar (gauge) and ambient temperatures of +2 to +50 °C. The pressure drop is 0.1 to 0.3 bar, depending on the flow.
How does it save energy?
The purge air control is consumption-optimised, and energy is used only when drying is actually required. This lowers operating costs over the entire service life.
Does it keep drying during a power failure?
Yes. Thanks to fail-safe operation, the DRYPOINT M eco control continues drying even during a power failure.
Can it be integrated into existing systems?
Yes. An analogue interface and a data transfer interface allow performance evaluation, for example with the METPOINT BDL data logger. Volt-free contacts pass status messages and alarms on to higher-level systems.
Is a filter integrated?
Yes, a nanofilter with 0.01 μm and 0.005 mg/m³ is integrated.
