In traditional HVAC systems, pumps often run at a constant full speed, regardless of the actual cooling demand. This leads to massive energy waste and unnecessary mechanical wear. A Variable Speed Drive (VSD), also known as a Variable Frequency Drive (VFD), allows the pump motor to adjust its speed dynamically to match the system's real-time requirements. EKG (Malaysia) Sdn Bhd specializes in VSD retrofitting and programming for HVAC pumps, helping businesses reduce energy consumption by up to 50% while extending the lifespan of their mechanical infrastructure.

Substantial Energy Savings – Following the "Pump Affinity Laws," a small reduction in motor speed results in a significant drop in power consumption.
Reduced Mechanical Stress – "Soft start" and "soft stop" features eliminate the damaging effects of water hammer and electrical surges.
Improved System Control – Maintains constant pressure or temperature differentials (Delta-P/Delta-T) for superior indoor comfort.
Extended Equipment Life – Lower operating speeds mean less friction and heat on bearings, seals, and motor windings.
Noise Reduction – Operating at lower RPMs significantly reduces the audible "hum" and vibration in mechanical rooms.
Conducting pre-installation power measurements to estimate potential energy savings.
Providing a Return on Investment (ROI) analysis to justify the upgrade for facility management.
Expert mounting and wiring of high-efficiency VSD units (e.g., Danfoss, ABB, Schneider) to existing HVAC pump motors.
Ensuring proper harmonic filtering to protect the building's electrical sensitive equipment.
Installing and calibrating pressure transducers and temperature sensors for closed-loop control.
Programming PID (Proportional-Integral-Derivative) loops for precise, automated speed adjustments.
Connecting the VSD to the Building Management System (BMS) for centralized monitoring and data logging.
Setting up remote fault alerts and performance tracking.
Implementing line reactors or active filters to mitigate electrical noise caused by high-frequency switching.
Ensuring the motor is "Inverter Duty" rated to handle VSD-driven power cycles.
Full system testing to ensure the VSD responds correctly to varying load conditions.
Training on-site facility teams on how to monitor and adjust VSD settings for optimal performance.
