Does your compressed air station work economically? RENNERconnect is a higher level, intelligent control system for optimal management and monitoring of your compressed air station. RENNERconnect contributes to efficiency and is highly reliable. Intelligent, air-demand based connection of the compressors provides not only a high energy savings potential, but also ensures increased operational reliability of your compressors.

Features of the RENNERconnect:

Regardless of the compressor type, up to 16 compressors can be controlled:

• RENNER compressors
• compressors of other manufacturers
• standard compressors with load and idle control

All compressors operate in a common, narrow pressure band, which means:

• all compressors are activated at the same switch on/off pressure
• pressure band can be reduced to a minimum
• high potential for energy savings, as pressure can be reduced maximally
• older compressor stations can be operated more economically

RS485-bus-system:
All compressors are connected via RS485-bus-system.

Connection to additional components:
RENNERconnect can connect to various additonal components in your compressor room and monitor them (e.g. dryer, drain, dew point sensor, flow sensor, additional pressure sensors).

DIN ISO 50001:
The control system can be used as energy management tool according to DIN ISO 50001 (section 4.6.1. monitoring, measurement, analysis). Contact us, we gladly provide you with information!

Extremely low switching frequency:
Extends the service life of all mechanical components of the compressors


Particularly low energy cost:
Due to constant calculation of air consumption which ensures an efficient use of compressor capacity

Advantages of the RENNERconnect

• compressors with RENNERtronic, RENNERtronic Plus, RENNERtronic Touch, RENNERtronic Plus Touch or RENNERlogic can be directly connected to RENNERconnect.
• compressors of other manufacturers can be connected by simply applying a compact connecting module.
• maximum energy savings (up to 40%) by avoiding expensive idle time and load / unload switching cycles, pressure optimization by 4 adjustable pressure bands and by reduction of maximum pressure.
• extends the service life of suction controls, air ends, contactors and motors! The service cost corresponds to the actual load times.
• RENNERconnect matches the use of the compressors automatically with the demand for compressed air in order to generate just the right amount needed for production.

In control of your compressed air station – always and everywhere

• webserver is part of every RENNERconnect control system
• all current measurements are displayed on webserver
• up to date online analysis of the operation of the compressors and other equipment
• statistical analysis of all parameters in daily, weekly, or monthly reports
• compressors and equipment can be set and parameterized via webserver
• optionally: automatic forwarding of daily reports
• calculation of service dates in accordance with operating hours of compressor
• remote control of pressure profiles, sequences and timer via webserver

An integrated service and alarm management will be provided by the option „Webserver Plus“:

• sending eMails in case of faults, warnings, and maintenance
• message, if limit values of pressure, dew point, and temperature are exceeded fall below minimum

With the introduction of the RENNERconnect EASY control, we offer you a consumption-dependent compressor control, which can simultaneously control up to 4 compressors with the usual range of functions of the existing RENNERconnect control. It is characterized by high efficiency and reliability. By switching on the compressors intelligently, based on consumption, you not only tap into large potential energy savings, but also increase the operational safety of your machines.

Regardless of the compressor type, up to 16 compressors can be controlled:

• RENNER compressors
• compressors of other manufacturers
• standard compressors with load and no-load control

All compressors operate in a common, narrow pressure band, which means:

• all compressors are activated at the same switch on/off pressure
• pressure band can be reduced to a minimum
• high potential for energy savings, as pressure can be reduced maximally
• older compressor stations can be operated more economically
