A compact, totally enclosed Twin Pump unit, it uses a digital processor to automate the sampleisolatevacuumventreintroduce cycle (with turbo mode for rapid commissioning). Top-up capacity is <18 L/min; an 18 Ltrs additive tank blends inhibitor at the point of fill. Guide system volume: up to 300,000 Ltrs.

• Category 5 protection (Type AB weir overflow)
• MODBUS RTU communications; password-protected access
• Mix ratios user-set from 150% via balancing valves
• Pressure setpoints in 0.1 Bar increments

Ideal for commercial plantrooms, the black (RAL 9005) enclosure includes sequential programming, system fill mode, pump-pulse, flood-protection routines and comprehensive event logging.

Real-world product applications
