RENNER screw compressors with refrigeration dryer and frequency control

The RSF models are fitted as standard with the intelligent RENNERtronic control and monitoring system. This optimizes their economy of operation and guarantees the necessary safety and reliability in terms of maintaining and servicing the units. They are compatible with higher-level compressed air management systems.

The RSKF is a self-contained compressed air station. No additional outlay required to fit frequency converter and refrigeration dryer. Simply plug in and connect to the pressure system and your RENNER compressor will be a reliable and economic source of compressed air.

The compressed air is delivered to the refrigeration air dryer for conditioning and pre-cooling in the air-to-air heat exchanger.

This pre-cooling process takes place counter-current to the outgoing cool treated air. No additional energy is required for this. The air is cooled further still to the pressure dew point in the refrigerant-to-air heat exchanger which is cooled by a refrigerant circuit.

Throughout the cooling process, moisture in the form of condensate is precipitated out and automatically discharged from the system. Before it is emitted, the conditioned compressed air is reheated in the air-to-air heat exchanger by the incoming hot compressed air. RENNER refrigeration dryers are environmentally sound and run on the ozone-friendly refrigerant R134a.
