Complete Guide to Commercial WCPU Water Cooled Packaged Units

EKG Malaysia Sdn Bhd – Your Expert Partner in Advanced Commercial HVAC Solutions

Water Cooled Packaged Units (WCPU) are highly efficient, self-contained indoor HVAC systems designed specifically for commercial applications in Malaysia's hot and humid climate. These units integrate all major components — including advanced scroll compressors, evaporator coil, water-cooled condenser, expansion device, blower fan, and controls — into a single compact cabinet. Heat is rejected to condenser water, which circulates to a cooling tower (typically rooftop-mounted), eliminating the need for noisy outdoor equipment.

WCPU systems excel in urban commercial environments where rooftop space is limited, building aesthetics must be preserved, or noise regulations are strict. They are widely used across Malaysia for reliable, energy-efficient cooling in offices, retail malls, hotels, high-rises, hospitals, data centers, and industrial facilities.

How Commercial WCPU Systems Work

In a typical WCPU setup:

• Warm indoor air is drawn over the evaporator coil, where refrigerant absorbs heat and cools the air.
• The refrigerant vapor is compressed by the scroll compressor(s).
• High-pressure vapor releases heat in the water-cooled condenser to circulating condenser water.
• Cooled condenser water is sent to a cooling tower for heat rejection to the atmosphere.
• The process repeats in a closed refrigerant loop, with microprocessor controls ensuring precise operation, staging, and diagnostics.

Advanced scroll compressors (often hermetic, single or multiple for staging) provide smooth, continuous compression with up to 70% fewer moving parts than reciprocating types — resulting in higher efficiency, lower noise, and superior reliability.
