Noch höhere Druckgrenzen, mehr Leistung - ESK-Ölspiegelregulatoren der Serie ERM5: Jetzt neu im Programm:

Coming soon:
New ESK Oil level regulator series ERM5
 
in 1999 we started the sale of our first generation of optoelectronic oil level regulators and level controls. We are proud to present you our 5th generation of this product class which incorporates improved features.
 
⇒ NEW:  Due to the application of more powerful solenoid valves, our oil level regulators are approved for pressure differences of 1.5 bar up to 100 bar now. The maximum working pressure up to the solenoid valve is 130 bar. The main body connected to the compressor is approved for 60 bar or 130 bar (type: ERM5-CDH). The main dimensions and all connectors remain unchanged.
 

Developed for frequency controlled compressors

The importance of frequency controlled compressors for modern refrigeration systems is increasing. Frequency controlled compressors have variable oil carry over rates. With the types ERM5-OC-FU* and ERM5-0-BC-FU* we offer new versions, which recognize if the oil carry over exceeds to oil return from the oil management system. This is signalized by a relay contact which can be evaluated by the system control. Therefore it is possible to reduce the compressor frequency for period of time. By using this method it is possible to increase the operational safety considerably.          (* available from 01.2016)
