For sale is a package of RENNER RSF screw compressors in an industrial design.

All machines come from an industrial test bench system in our own facility and were procured for a development project. Due to a project change, the test benches never went into productive operation. The compressors were then dismantled and stored.

This is a specially configured industrial design with special features and practically no productive runtime:

- Frequency control
- RENNERtronic Plus control system
- Modbus interface – integration into building automation systems possible
- allowing external setpoint input (pressure/speed)
- Water cooling
- Design for high cooling water temperatures (60/80 °C) – but does not necessarily have to be used
- High outlet temperature for efficient heat recovery (ideal for heating support)

Technical data
RSF 85
85 kW
Frequency-controlled
Operating pressure 5–10 bar
Flow rate up to approx. 14.5 m³/min
Water cooling
RENNERtronic Plus
Modbus

RSF 45
45 kW
Frequency-controlled
Operating pressure 5–10 bar
Flow rate up to approx. 7.25 m³/min
Water cooling
RENNERtronic Plus
Modbus

The compressors were specifically designed for the utilization of waste heat. The water cooling allows high cooling water temperatures to be achieved, making the systems ideally suited for heat recovery and feeding into heating systems.

The operating pressure can be increased to up to 15 bar by a modification of the pulleys and V-belts as provided by RENNER. A corresponding offer from RENNER is available, but the modification was never needed.

Inspection:
The machines are dismantled and stored.
An inspection is possible at any time by appointment.

We will gladly send further photos, nameplates and technical documents upon request.
Price: Negotiable / Offers welcome.
