Flexdrive is a conversion kit developed by Maximator to reduce the air consumption of high pressure compressors. The modification can be implemented for all MAXIMATOR compressors with two air drive parts and is used in the following applications:
The implementation of energy-efficient measures is an important contribution to climate change. With this in mind, Maximator GmbH has developed various product-related optimizations in order to achieve ecologically effective efficiency-increasing goals.
The Flexdrive ensures that the relatively high costs for and the high consumption of drive compressed air are reduced. The reduction in consumption is up to 40 %, the filling times for conveying and compressing the compressed air into the system are reduced by up to 20 %. Another profitable benefit is the reduction in process times. Existing compressors can be converted, retrofitted or equipped with a minimal effort of 15 minutes.
Benefits:
Flexdrive thus ensures overall lower operating costs, shorter process times and thus brings economic and ecological advantages with it. There is a very high potential for savings, particularly with large container volumes and low inlet pressures.
| Savings | ||
| Bottle filling from 30 bar to 400 bar target pressure with a DLE 30-75-2 | ||
| Storage volume | Compressed air savings | Filling time savings |
| 3 liter | 32 % | 22 % |
| 20 liter | 34 % | 23 % |
| 50 liter | 36 % | 24 % |
| Bottle filling from 30 bar to 250 bar target pressure with a DLE 30-2 | ||
| 3 liter | 20 % | 4 % |
| 20 liter | 22 % | 4 % |
| 50 liter | 38 % | 4 % |
| Bottle filling from 40 bar to 700 bar target pressure with booster combination 2x DLE 30-2 / 2x DLE 75-2 | ||
| 120 liter | 27 % | 7 % |
The following diagram shows the savings potential of Flexdrive in terms of outlet pressure and air consumption.
About 80 % of the Maximator applications in the gas industry deal with filling and transferring processes. The compressibility of the gases causes an increasing expenditure of force to generate pressure. This means that the transmission ratio determines the ultimate pressure. With 2 drive parts, only a low drive pressure can be compensated, whereby the greatest possible force is only required later in the process. This is where Flexdrive comes in. It combines the low air consumption at the beginning of the process with the force required at the end.
The strengths of Flexdrive are:
Possible uses can be found among others
Flexdrive can be used with all Maximator compressed air boosters with at least 2 air drives.
All new systems as well as systems from the last 2 years can preferably be upgraded or converted. The conversion is conceivable for older models.
Flexdrive conversion kit is available in 3 different versions:
Manual valves are installed for manual actuation. As soon as there is an equilibrium of forces on the drive side and the high pressure side, the booster stops (standstill pressure). A ball valve is then used to switch to the two-piston drive. This version is used in laboratories, for example, since the filling time does not play a decisive role here.
Pneumatically operated valves are installed in pneumatic actuation. They are controlled via a pressure switch. This allows you to switch between single-piston and two-piston drive depending on the operating pressure.
In the electrically operated version, electrically controllable valves are built in, which can also be integrated into an existing PLC. The switch between single and two-piston drive takes place within the PLC using a pressure transmitter. Stored switching pressures and solenoid valves ensure switching to the more efficient mode.
