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
