AIRLEADER MASTER II+ is the standard. With the AIRLEADER MASTER II+ up to 16 compressors - 2 (opt. 8) speed controlled (FU) - and 16 accessory modules can be connected.

AIRLEADER MASTER II+ controls all compressors as required. Only as many compressors run as necessary, unnecessary idling is avoided, the station works with maximum possible efficiency.

Depending on the network volume and the compressor dynamics, a pressure range of only +/- 0.15 bar can be achieved with minimal switching frequencies at the same time - that is maximum energy efficiency with gentle compressor use at the same time.

AIRLEADER MASTER II+ is configured via the standard 7 "color touchscreen or via the integrated web interface - either using a network cable (RJ 45 ETHERNET interface) or via the standard WiFi WLAN hotspot with smart devices (laptop, tablet, smartphone).

Standard WEB server visualization

The Airleader visualization shows very transparently how things are going with compressed air - good or bad! Inefficient compressors are unmasked and you can take targeted action against efficiency damage among the compressors!

The WEB server visualization is standard and is supplied on a data carrier. In the event of loss or for an update, the web server can be downloaded free of charge from our homepage: > software

The web server is installed on a customer's own server and thus ensures that the data stays inhouse.

The data is stored redundantly in the hardware memory of the Airleader, so that server interruptions or subsequent installation of the web server do not lead to data loss.

Airleader MASTER II+ automatically optimizes up to 16 compressors

and adapts itself to changes in a self-learning manner. Using iterative computing processes, Airleader MASTER II+ permanently and automatically determines the network dynamics, the network volume and other parameters. There is no need for time-consuming adjustment, running-in, adjustment, etc.

Simple operation

All you have to do is enter the compressor delivery quantities and the desired pressure range. Ready - Airleader MASTER II+ takes care of everything else.

Airleader MASTER II+ monitors ancillary units

The monitoring of ancillary units such as dryers, filters, beers, etc. is also possible and leads to notification of the operator in the event of a fault. Measurement in the compressors is provided as standard.

Manufacturer independent

All compressors are automatically formed into a unit that adjusts to production based on the current compressed air consumption. It is ensured that only the most efficient compressor combination generates the compressed air that is required for production, regardless of manufacturer and performance. The compressor combination works with sensible hysteresis calculation, with minimal load / idle switching cycles and thus the lowest idle times. Instead of idling the large compressors, the right combination runs under load, with the smallest compressor clocking.

Pressure band control

Keep the costs as low as possible. The possibility of connecting several distributed pressure sensors means that operating parts that are further away can be monitored and integrated into the control pressure. If a running compressor fails within the pressure band or is switched off for maintenance, its capacity is immediately replaced by one or more other compressors.

8 times the self-learning calculation depth

It ensures that the compressors are dynamically adapted to the compressed air consumption. The compressed air consumption and dynamics are continuously calculated and evaluated in different time windows. If necessary, the correct compressor combination will be switched. Unnecessary switching cycles are prevented.

Base load changes for even work load

Compressors with the same output have the same operating hours. If a specified time delay is reached, the compressors are exchanged without a pressure drop within the pressure band.

Ranking profilesallow intervention

The compressors can work with different priorities by manually defined ranks. This function is often used for compressors with heat recovery (preferred priority) or reserve compressors (lower priority). Compressors of the same rank, work automatically depending on consumption.

Speed-controlled compressors are actively integrated

The speed-controlled compressors send information about the compressor speed to the Airleader EASY via their analog output. Programmable control limits allow uneconomical areas to be masked out individually so that the regulated compressor can always run in the energetically favorable speed range.

Integrated data memory for 20 years

with every second recording and storage of 10 seconds average values ​​of all compressor states, sensor values ​​and messages in the Airleader MASTER II+ itself. These can can be read out at any time using a USB stick. When connected to the network, all data is kept in parallel in the web visualization and permanently synchronized on the customer server.
