## Overview

 

 

 

The nephRO® SAFE system ensure bacterial free permeate through the combination of continuous ultrafiltration during dialysis operation, followed by automatically programmed heat disinfection with the optimum consumption of both water and power.

**Features & Benefits**

- The functional, hygienic design and the use of high quality stainless steel ensures the high reliability and long life of the nephRO® SAFE
- High efficiency thermal insulation and the double-walled structure of the tank ensures low power consumption
- The frequency-controlled pressure pump ensure optimum pressure and flow conditions in the distribution ring
- The nephRO® SAFE is manufactured completely from stainless steel which is surface-treated to maintain optimal hygiene to all fluid ways
- A completely dead zone-free design is ensured through hygienic clamp connectors
- Dead zone-free measurements in the tank is performed through state-of-the-art liquifants sensors
- The temperature in the tank is maintained constantly at >85°C, eliminating microbiological contamination
- Sampling points permit convenient and safe microbiological analysis of the permeate

**Applications**

- The symbiosis of ultrafiltration and heat-disinfection for guaranteed ultrapure permeate through into the dialysis machine.
