EKG (MALAYSIA) SDN BHD is a professional commercial HVAC engineering company specializing in retrofit and upgrade solutions for Water Cooled Packaged Units (WCPU). This guide is designed to help building owners, facility managers, and industrial operators understand how aging water cooled packaged units can be modernized to improve energy efficiency, cooling performance, and system reliability—without the high cost of full unit replacement.
With extensive experience in water-cooled HVAC systems across commercial and industrial environments, EKG delivers engineered retrofit strategies that maximize asset value and long-term operational performance.
A WCPU retrofit and upgrade involves improving key mechanical, electrical, and control components of an existing water cooled packaged unit while retaining usable infrastructure such as chilled water piping, condenser water circuits, cooling towers, and plant rooms. Retrofit works are targeted to address performance degradation caused by aging equipment, corrosion, fouling, and outdated controls.
EKG (MALAYSIA) SDN BHD performs comprehensive system assessments to determine the most effective and cost-efficient upgrade options.
EKG provides a full range of WCPU retrofit and upgrade solutions, including:
High-efficiency compressor replacement or optimization
Condenser and evaporator re-tubing or refurbishment
Electrical system and motor efficiency upgrades
Variable Speed Drives (VSD) for compressors and pumps
Smart control systems with PLC and BMS integration
Chilled water and condenser water flow optimization
Hydraulic balancing and system performance tuning
Noise, vibration, and corrosion mitigation
Energy monitoring and system efficiency optimization
These upgrades significantly improve Coefficient of Performance (COP), system stability, and long-term reliability.
For many commercial buildings, replacing an entire WCPU system is costly and disruptive. Retrofit and upgrade solutions offer:
Lower capital expenditure compared to full replacement
Reduced downtime and minimal disruption to operations
Improved energy efficiency and reduced electricity costs
Extended service life of existing HVAC assets
Compliance with modern energy efficiency standards
EKG focuses on maximizing return on investment (ROI) through targeted, performance-driven upgrades.
