EKG (MALAYSIA) SDN BHD is a leading commercial HVAC engineering company specializing in retrofit and energy-saving upgrade solutions for Water Cooled Package Units (WCPU). Our services help commercial and industrial facilities maximize cooling efficiency, reduce energy consumption, and extend the life of existing WCPU systems without the high cost and disruption of complete unit replacement.
With extensive experience in water-cooled HVAC systems for offices, hotels, hospitals, retail complexes, and industrial plants, EKG delivers engineered retrofit strategies that improve energy performance, reduce operational costs, and ensure reliable, consistent cooling performance.
Over time, WCPU systems can experience:
Decreased cooling efficiency and inconsistent indoor temperatures
Higher electricity consumption and operational costs
Frequent breakdowns and increased maintenance needs
Component wear, corrosion, and fouling
Outdated control systems lacking automation and monitoring
Energy-efficient retrofits from EKG (MALAYSIA) SDN BHD address these issues by upgrading mechanical, electrical, and control components, creating a modern, high-performance, energy-efficient HVAC system.
Our WCPU retrofit services include:
High-efficiency compressor replacement or optimization to restore cooling capacity
Condenser and evaporator re-tubing or refurbishment for improved heat transfer
Electrical system and motor efficiency upgrades
Variable Speed Drives (VSD) for compressors, pumps, and fans
Smart controls, PLC, and BMS integration for automated energy management
Hydraulic balancing and water flow optimization
Noise, vibration, and corrosion mitigation
Energy monitoring and performance analytics for measurable improvements
These solutions improve Coefficient of Performance (COP), system reliability, and operational efficiency, providing long-term energy and cost savings.
Investing in retrofit and energy-saving upgrades provides:
Reduced energy consumption and lower utility costs
Improved cooling performance and consistent indoor comfort
Extended equipment life and deferred replacement costs
Lower maintenance frequency and reduced downtime
Compliance with modern energy efficiency standards and sustainability initiatives
All retrofits are validated through pre- and post-upgrade performance benchmarking, ensuring tangible results and ROI for building owners.
Retrofits are recommended when:
Systems are 10–20 years old or showing declining efficiency
Energy consumption continues to rise
Cooling performance no longer meets operational requirements
Maintenance and downtime affect facility operations
Facility renovations, upgrades, or sustainability initiatives are planned
EKG (MALAYSIA) SDN BHD provides technical assessments and customized retrofit plans to maximize efficiency and operational performance.
