EKG (MALAYSIA) SDN BHD is a specialized commercial HVAC engineering company providing retrofit and modernization solutions for Water Cooled Package Units (WCPU) used in commercial and industrial buildings. This guide explains how aging water-cooled systems can be upgraded to meet modern efficiency, reliability, and operational standards—without the cost and disruption of full HVAC replacement.
With extensive hands-on experience in commercial water-cooled HVAC systems, EKG delivers engineered retrofit strategies that improve energy efficiency, extend equipment lifespan, and ensure long-term system performance.
WCPU retrofit and modernization involve upgrading mechanical, electrical, and control components of existing water cooled packaged units while retaining serviceable infrastructure such as chilled water piping, condenser water circuits, cooling towers, and plant rooms.
As buildings age and usage patterns change, original HVAC designs may no longer meet actual cooling demand. EKG (MALAYSIA) SDN BHD evaluates system performance against current requirements to determine the most effective modernization approach.
EKG provides a comprehensive range of WCPU retrofit and modernization solutions, including:
High-efficiency compressor replacement or upgrade
Condenser and evaporator re-tubing or refurbishment
Electrical system and motor efficiency upgrades
PLC-based controls, smart automation, and BMS integration
Pump and water flow optimization
Hydraulic balancing and chilled water system tuning
Noise, vibration, and corrosion mitigation
Energy monitoring and performance optimization
These upgrades significantly improve Coefficient of Performance (COP), system stability, and operational reliability.
For many commercial buildings, full HVAC replacement is costly and disruptive. WCPU retrofit and modernization offer:
Lower capital expenditure compared to new system installation
Shorter downtime and minimal disruption to building operations
Improved energy efficiency and reduced electricity consumption
Extended service life of existing HVAC assets
Compliance with modern energy efficiency and safety standards
EKG’s modernization approach is designed to maximize return on investment while ensuring long-term reliability.
