Energy-efficient Chiller Pump Retrofitting

Upgrade for savings, reliability, and modern performance.
Retrofitting your existing chiller pumps with high-efficiency motors, variable speed drives (VSDs), and modernized controls can deliver rapid energy savings, improve system stability, and extend equipment life. EKG Malaysia specializes in turnkey retrofit solutions—minimizing downtime and maximizing your return on investment.

Common Retrofit Solutions We Implement:

1. Constant to Variable Speed Upgrade

   • Installation of a Variable Frequency Drive (VFD) on existing pump motors.

   • Integration with pressure/flow sensors and BMS for demand-based control.

2. Motor Replacement for Efficiency

   • Swapping out standard motors with IE3/IE4 high-efficiency models.

   • Includes mechanical re-alignment and electrical re-commissioning.

3. Complete Pump Replacement

   • Replacing old, oversized, or worn pumps with correctly sized, high-efficiency units.

   • Modern end-suction or inline pumps that match the actual system curve.

4. Hydraulic & Control Optimization

   • Replacing throttling valves with automated balancing valves.

   • Implementing pressure reset strategies and optimizing control sequences.

The Retrofitting Process:

• Energy Audit & Assessment – We measure current pump performance (flow, head, power) and identify savings potential.

• Solution Design & Proposal – Detailed scope, savings calculation, ROI timeline, and project plan.

• Minimal-Dowtime Installation – Careful planning and staging to keep the system operational where possible.

• Commissioning & Verification – Post-retrofit performance testing to validate energy savings and system operation.

• Documentation & Support – Updated drawings, O&M manuals, and staff training.

Expected Benefits & ROI:

• Energy Savings – Typically 20–50% reduction in pump energy consumption.

• Improved Control – Better temperature and pressure stability.

• Reduced Maintenance – Less wear on bearings, seals, and motors.

• Extended System Life – Modern components and gentler operating profiles.

• Sustainability Contribution – Lowers carbon footprint and supports green building certifications (GBI, LEED).
