Special features/Product advantages
- Maximum efficiency thanks to ECM technology
- Front operation and access to terminal room, variable installation positions, display independent of position
- Simple installation due to PN 6/PN 10 combination flanges (with DN 32 to DN 65)
- Application possible in cooling/air-conditioning systems without ambient temperature limitation
- Pump housing with cataphoretic (KTL) coating to prevent corrosion due to condensation formation
- System expansion by means of retrofittable interface modules for communication: Modbus, BACnet, LON, CAN, PLR etc.
- Remote control via infrared interface (IR stick/IR monitor)
- Integratable dual pump management by means of retrofittable Stratos IF-modules for:
- Main/standby operation with fault-dependent switchover
- Efficiency-optimised peak-load operation
Technical data
- Permissible temperature range ‐10 °C to +110 °C
- Mains connection 1~230 V, 50/60 Hz
- Protection class IPX4D
- Flange connection DN 32 to DN 80
- Max. operating pressure, standard version: 6/10 bar or 6 bar (special version: 10 bar or 16 bar)
