High Heat Load & Cooling Challenges
● Rack power density in data centers is increasing, often exceeding 10kW per rack.
● Electronics manufacturing equipment generates significant waste heat, difficult to handle with traditional cooling methods.


● Rack power density in data centers is increasing, often exceeding 10kW per rack.
● Electronics manufacturing equipment generates significant waste heat, difficult to handle with traditional cooling methods.
● Cooling accounts for over 40% of total data center energy usage.
● Manufacturing HVAC systems run continuously, leading to high electricity bills and maintenance costs.

● Data centers require tight control: ±1°C temperature range and 40–60% humidity.
● Electronics production is humidity-sensitive: high humidity risks oxidation, while low humidity increases static discharge risks.
● Any cooling system failure can cause downtime or production loss.
● Industry demands N+1 or 2N redundancy, but these often increase capital and energy costs.
● Both industries face carbon neutrality goals and stricter emission targets.
● Regulations are tightening on refrigerants and energy efficiency standards worldwide.

High-efficiency filters (HEPA / ULPA, MERV13 or above) to remove particles and pathogens; positive/negative pressure control in clean zones to prevent cross-contamination.

Use hot aisle/cold aisle containment, positive pressure in clean zones, and negative pressure in exhaust areas. High air-change rates ensure heat and contaminants are diluted quickly.

Maintain stable conditions (e.g., 18–27°C and 40–60% RH, per ASHRAE guidelines). Proper dew point and rate-of-change control help prevent condensation and electrostatic issues.


24/7 continuous operation requires backup chillers, fans, UPS power, and dual-path or N+1 configurations for mission-critical equipment.

Apply free cooling, liquid cooling, and heat recovery technologies. Intelligent control and optimization strategies help reduce overall power usage effectiveness (PUE).

Online monitoring for temperature, humidity, air quality, and pressure differential, combined with regular filter replacement, system calibration, and cleanroom validation.
