System Separator BA prevents back pressure, backflow, and back siphoning of utility water into the drinking water network. The System Separator BA from SYR contains all components specified by the DIN EN 1717 standard and, as a three-chamber system, is equipped with a controllable zone of front, middle, and rear pressure.

The practical design allows for a quick check of the system separator's status. With a single glance, you can determine whether the system separator is open or closed. When water is not being drawn, the check valves at the inlet and outlet are closed. In the event of back siphoning, the pressure on the inlet side drops. The discharge valve opens at the latest when the differential pressure between the front and middle pressure chambers falls to 0.14 bar.

Easy Maintenance
With a simple hand movement, the safety cartridge, controlled by differential pressure, and the built-in dirt trap can be replaced. The ball valves of the three pressure zones allow for a functional test of the fittings with the appropriate measuring instruments.

Areas of Application:

• water softening/ deacidification, regeneration
• swimming pools and baths with water treatment and disinfection
• chemical mixing equipment (disinfectants or fertilizers)
• chemical cleaning machines
• printers, reprographic operations, photographic workshops, film development equipment
• bathroom lifts, openings and functional parts above the edge of the tub
• galvanic baths
• sterile water, production with disinfection
• heating filling equipment (water with inhibitors)
• high-pressure cleaners with chemical additives
• laboratory tables, chemical laboratory
• softening/ deacidification equipment, formalin disinfection (dialysis)
• sterilizers for carcinogenic material
• gas generators (e.g., acetone)

Unsuitable Installation:

• rooms with a risk of flooding
• frost
• high temperatures
• can only be installed if the potential backflow volume does not exceed the discharge capacity of the safety device
