DRYPOINT® ACM
Desiccant dryer for medium compressed air volumes up to 1,000 m³/h
Where a refrigeration dryer reaches its limits, the DRYPOINT® ACM takes over: it reliably dries compressed air down to a pressure dew point of −40 °C, and even down to −70 °C on request. This protects sensitive equipment, tools and products against moisture, corrosion and breakdowns.
BEKO TECHNOLOGIES developed and built the new series entirely in-house. The result is a compact dryer that fits easily into existing compressed air stations and machines and, with its clear control system, shows at all times what it is doing.
Flow rate
100 to 1,000 m³/h
Pressure dew point
down to −40 °C, optionally −70 °C
Operating pressure
4 to 16 bar
Why the DRYPOINT ACM?
Dry compressed air is not an end in itself. It determines whether valves switch cleanly, paint finishes succeed and pipes stay free of rust inside. The DRYPOINT ACM provides this security for businesses with medium compressed air demand, without you needing a large, central drying system.
Filtration, condensate drainage and control are already built in. You connect the dryer, set the required pressure dew point and from then on have consistently dry air, even when consumption fluctuates.
- Economical to run: low pressure loss and regeneration based on actual demand
- Runs in step with the compressor: synchronisation control as standard
- Clean from the start: CLEARPOINT® pre-filter and BEKOMAT® condensate drain integrated
- Everything at a glance: colour display with live values, warnings and alarms
- Ready for the control system: Modbus interface for connection to higher-level systems
- Compact and flexible: fits into compressed air stations, on skids and in machines, also as an OEM solution
Where the DRYPOINT ACM is at home
Packaging and automation
Pneumatic drives and grippers only work reliably if no moisture gets into the lines. Dry air prevents malfunctions and unplanned downtime.
Mechanical engineering
Whether precision machining or assembly: dry compressed air protects tools and components and ensures consistent quality.
Medium air demand
For production lines and systems that need more air than a small point-of-use dryer can supply but do not justify a large central system.
OEM and system building
Thanks to its compact design and flexible connections, the ACM can be integrated directly into compressor packages and your own systems.
How the DRYPOINT ACM works
The dryer works with two vessels that alternate. The moist compressed air first flows through the CLEARPOINT® pre-filter and the BEKOMAT® condensate drain. The desiccant in the active vessel then removes the remaining moisture from the air until the set pressure dew point is reached.
Meanwhile, the second vessel is regenerated: a small portion of the already dried air flows through it in the opposite direction and carries away the stored moisture. Switching is based on time or, on request, on the actual measured dew point. This means the dryer only regenerates as often as necessary.
Control with clear insight
New on the DRYPOINT ACM is the built-in DP-ACM controller. Its colour display shows operating mode, timer control and dew point as well as all status, warning and alarm messages at a glance. You can see immediately whether everything is running smoothly and find the cause if it is not.
It is operated using a few clearly labelled buttons directly on the dryer. Via the optional Modbus interface, the dryer also reports its values to your control system. And if the power fails, the compressed air supply is still maintained.

Frequently asked questions
When do I need a desiccant dryer instead of a refrigeration dryer?
A refrigeration dryer achieves a pressure dew point of around +3 °C. That is sufficient for many applications. If pipes run outdoors or through cold rooms, or if your process requires very dry air, for example in food, pharmaceutical or electronics manufacturing, you need a desiccant dryer such as the DRYPOINT ACM.
What pressure dew point does the DRYPOINT ACM achieve?
Down to −40 °C as standard, down to −70 °C on request. With air this dry, no condensate forms even in the cold: pipes do not rust and your products stay free of moisture.
How economical is it to run?
The dryer operates with low pressure loss and, on request, only regenerates when the measured dew point requires it. This means as little as possible of the expensively generated compressed air is lost.
How much maintenance does the DRYPOINT ACM need?
Little: the filter elements are replaced regularly, and the dryer and control are briefly checked. All maintenance parts are easily accessible. On request, our AIR-Service can take care of maintenance for you.
Will the dryer fit into my existing system?
In most cases, yes. The ACM is compact and available with 1 to 2 inch connections. We will assess your compressed air station and suggest the right model.
What sizes are available?
Nine models cover flow rates from 100 to 1,000 m³/h at an operating pressure of 4 to 16 bar. The table above shows which model suits your needs.
What is already built into the dryer?
The CLEARPOINT® pre-filter, the BEKOMAT® condensate drain and the DP-ACM controller with colour display. You do not need to plan for any additional components.
Can the DRYPOINT ACM be connected to our control system?
Yes, via the Modbus interface. The dryer then reports operating mode, dew point, warnings and alarms to your higher-level system.
What happens in the event of a power failure?
The compressed air supply is maintained even then.
Which dryer suits your application?
Pressure dew point, flow rate and operating conditions determine which dryer is right. We provide manufacturer-neutral advice and find the model that suits your system.
