Variable Speed Pumping for HVAC and Hydropneumatic Pumps
Variable speed drives (VFDs) enhance energy efficiency and operational control in HVAC and hydropneumatic pump systems. They optimize water flow based on demand, reducing energy consumption and system wear while maintaining stable pressure and temperature levels.
Typical VFD Power Range:
HVAC Pumps: Typically used in chilled water and hot water circulation, with power ratings ranging from 1.1 kW to 500 kW.
Hydropneumatic Pumps: Used in water supply and pressure-boosting systems, available in the range of 0.75 kW to 250 kW.
AHU Fan Speed Control
VFDs regulate the speed of air handling unit (AHU) fans, adjusting airflow according to occupancy and ventilation requirements. This ensures energy savings, reduced noise levels, and enhanced indoor air quality while preventing over-ventilation.
Typical VFD Power Range:
Small AHU Fans: Typically range from 0.75 kW to 30 kW.
Large AHU Fans: Used in large commercial and industrial setups, ranging from 30 kW to 250 kW
Cooling Tower Fan Speed Control
VFDs control the speed of cooling tower fans to match heat rejection needs, reducing energy consumption and mechanical stress. This results in optimized cooling performance, lower operational costs, and extended equipment life.
Typical VFD Power Range:
Small Cooling Towers: Power range of 1.5 kW to 37 kW.
Large Cooling Towers: Used in industrial-scale cooling systems, available in 37 kW to 500 kW.
Ventilation Fan Speed Control
VFDs optimize the speed of ventilation fans in various applications, ensuring efficient airflow regulation while reducing energy consumption. By adjusting fan speed based on demand, they enhance system performance, minimize noise levels, and extend equipment lifespan.
Applications:
Building Ventilation – Ensures optimal indoor air quality by adjusting fan speed based on occupancy and environmental conditions.
Basement Jet Fan Ventilation – Controls airflow in enclosed spaces, improving air circulation and removing pollutants efficiently.
Tunnel Ventilation – Regulates fan speed to maintain proper airflow, ensuring safety and compliance with air quality standards.
Power Range:
Available in a wide range of power capacities, VFDs for ventilation fan control cater to small-scale building ventilation as well as large tunnel systems, providing precise airflow management and energy
