In the mission-critical environments of KL and PJ, standard comfort air conditioning is not enough. Data centers, medical labs, and semiconductor facilities require Precision Air Conditioning (PAC)—also known as Close Control Units (CCU)—to manage high sensible heat loads and maintain strict tolerances for temperature and humidity 24/7.
At EKG M&E Sdn Bhd, we engineer PAC systems that guarantee 99.9% uptime, protecting your high-value electronic assets from thermal failure and static discharge.

Sensible Heat Ratio (SHR) Optimization
IT equipment produces "dry" heat. Our PAC units are designed with a high SHR (typically 0.9 to 1.0), meaning almost all the cooling capacity is used to lower the temperature rather than just removing moisture. This is far more energy-efficient for server rooms than standard split units.
Precision Humidity Management
In the humid Klang Valley, moisture is a threat. We integrate electrode steam humidifiers and electric reheat coils. The system maintains a stable 45% to 55% Relative Humidity, preventing both "zinc whiskers" (from high humidity) and static electricity (from low humidity).
EC Fan Technology & High Static Pressure
We utilize Electronically Commutated (EC) Fans that offer superior efficiency and lower noise. These fans provide the high static pressure required to push cold air through raised floors (plenums) and dense server racks.
N+1 Redundancy and Auto-Sequencing
We design for "No Single Point of Failure." Our PAC systems feature dual power inputs and auto-sequencing logic; if one unit requires maintenance or fails, the standby unit kicks in immediately, and the Building Management System (BMS) sends an instant alert.
Advanced Filtration (MERV 13 / HEPA)
To protect sensitive PCB components from dust buildup, we equip PAC units with high-efficiency filters. For specialized labs, we integrate H13 HEPA filtration to maintain ISO Class 8 cleanliness or better.
Data Centers & Server Rooms: Managing the high-density heat of blade servers.
Telecommunication Hubs: Ensuring 24/7 cooling for switching equipment.
Medical Imaging (MRI/CT Scan): Maintaining stable temperatures for sensitive medical magnets and electronics.
Laboratories & Pharmacies: Preventing chemical degradation through strict environmental control.
HVAC & Clean Air Specialist: We don't just "install a box." We perform a full Heat Load Calculation and Airflow Simulation to ensure your PAC unit is sized correctly for your current and future hardware expansion.
Energy-Led Engineering: By utilizing Variable Frequency Drives (VFDs) and smart control logic, we ensure your PAC system scales its cooling output based on actual server load, significantly reducing your monthly TNB bill.
