Our customers are installing this design world-wide where open drive is an advantage. Fitted with the proven ".2-Generation" construction parts they employ a high quality metal bellows shaft seal, resulting in the following important advantages: suitable for all current refrigerants, especially NH3; facility to flange-on standard motors with a coupling housing or for belt drive, approved for explosion proof zones. For further information and accessories see leaflet KP-520. In addition to the fast running compressors a world-wide demand still exists for our classic 0-VII series. We believe this is due to the legendary reliability, ease of service and the possibility to use modern chlorine-free refrigerants (see leaflet KP-510).
