BOGE SLF Series Oil-Flooded Rotary Screw Compressors

The frequency controlled BOGE SLF series compressor offers a very flexible system which can easily adapt to any changes in volume or pressure demands. In the event of a change of the pressure value, the output quantity is automatically synchronized. A 13 bar machine thus regulated into an 8 bar machine would yield a correspondingly higher output – without any expensive reconstruction or design related modifications. The integrated heat exchanger also provides increased efficiency – giving an extra bonus in efficiency!

Performance and Benefits

Absolutely On Demand

The frequency converter is primarily integrated to control motor and airend speeds in order to produce the momentary air demand requirement at the required pressure. As an option, the cooling fan can be frequency controlled ensuring it only ever works as hard as necessary.

Maximum Efficiency

Frequency control is ideal where shift/production patterns create a fluctuating demand for compressed air or where there is a small storage volume or in a multiple installation for peak load operation. Built-in frequency control continuously adjusts the volume flow to the actual demand ensuring minimized idling times and pressure fluctuations providing an energy efficient solution.

High Efficiency

The centrepiece of the integrated DUOTHERM BPT heat exchanger is a plate heat exchanger through which passes hot oil around +85°C from the oil circuit. The counter-flow water passing through the heat exchanger is heated up to around +70°C, and can then be used as heating or production water.

Versatile Control

The convenient and user-friendly FOCUS control with its numerous control and monitoring features comes as a standard on this compressor.
