EKG (MALAYSIA) SDN BHD is a professional commercial HVAC engineering company specializing in retrofit and upgrade solutions for Water Cooled Packaged Units (WCPU). We help building owners, facility managers, and industrial operators improve energy efficiency, enhance cooling performance, and extend system lifespan without the high capital cost of full HVAC replacement.
With extensive experience in water-cooled HVAC systems across commercial and industrial environments, EKG delivers engineered retrofit solutions that restore system reliability, reduce operating costs, and support long-term sustainability goals.
Commercial WCPU retrofit involves upgrading critical components of an existing water cooled packaged unit while retaining usable infrastructure such as chilled water piping, condenser water systems, cooling towers, and plant rooms. Retrofit options are selected based on system condition, cooling load requirements, and operational objectives.
EKG (MALAYSIA) SDN BHD performs detailed system evaluations to recommend cost-effective, performance-driven retrofit strategies tailored to each building.
Our commercial WCPU retrofit options include:
High-efficiency compressor replacement or upgrading
Condenser and evaporator refurbishment or re-tubing
Electrical system, motor, and control panel upgrades
Smart control integration, PLC, and BMS connectivity
Pump, piping, and water flow optimization
Hydraulic balancing and system performance tuning
Vibration, noise, and corrosion protection enhancements
Energy monitoring and efficiency optimization solutions
These upgrades significantly improve Coefficient of Performance (COP), system stability, and long-term reliability.
Many commercial buildings operate WCPU systems beyond their original design life. Retrofit solutions offer:
Lower capital expenditure compared to full system replacement
Shorter project timelines and minimal operational disruption
Improved energy efficiency and reduced electricity consumption
Extended equipment lifespan and reduced maintenance frequency
Compliance with modern HVAC efficiency and safety standards
EKG focuses on maximizing return on investment (ROI) while ensuring consistent cooling performance.
