Siemens Variable Speed Drives for HVAC Control
Intelligent fan and pump speed control with Siemens G120P and V20 VSDs for precision energy savings and smooth motor operationWhat Are Variable Speed Drives
Variable Speed Drives (VSDs) regulate motor speed and torque in HVAC fans and pumps, enabling precise airflow or fluid control, extended equipment life, and up to 60% energy savings.
By reducing energy during partial loads, VSDs improve system efficiency, support building automation, and enhance operational reliability across HVAC operations.
Efficiency & Operational Savings
G120P delivers up to 60% energy savings on fans and pumps. V20 features ECO and Hibernation modes to dynamically reduce flux and lower power consumption.
Reliable & Compact Design
V20 supports 0.12–30 kW with Keep Running mode and EMC filters. G120P spans 0.37–630 kW in compact IP55-rated housings – ideal for HVAC systems.
Easy Commissioning & Integration
V20 uses Smart Access; G120P offers BOP-2 or portal setup. Both support Modbus RTU/USS, PROFINET, and BACnet for seamless smart building integration.
Robustness & Automation-Friendly
Built-in braking choppers, frost and condensation protection, and high overload capacity make both drives durable and automation-ready.
