Needs
Why Do You Need Special HVAC?
Clean Environment and Energy Efficiency
We analyze each facility's installation environment to design appropriate special HVAC (CR/DR) systems, followed by maintenance services to maintain cleanliness and optimize energy efficiency
Optimal Facility Conditions Through Customized Control
We reduce dust, volatile organic compounds (VOCs), and microorganisms while maintaining precise control of temperature, humidity, and pressure to ensure optimal working conditions
Scrubber Maintenance
Scrubbers, as exhaust gas treatment devices, purify and discharge various toxic gases. Regular maintenance is essential as treatment efficiency decreases and pipe corrosion occurs with long-term use
Building/Facility Maintenance
We calculate and design loads to improve indoor air quality and implement equipment suitable for the environment, creating comfortable workspaces and enhancing operational efficiency
Particle Control
Filter Maintenance and Replacement
Particle Removal
Temperature and Humidity Control
Pressure Control
Air Quality Monitoring
Special HVAC
What Is Special HVAC?
HVAC (Heating, Ventilation, and Air Conditioning) systems are categorized into general and special HVAC. Special HVAC is a specialized field that provides comprehensive control of environmental factors including temperature, humidity, air flow, air pressure, and air quality
Room Design
Room Design Solutions
Dry Room Solutions
Applications: Battery manufacturing, electrolyte production, bioscience, and more
A dry room maintains an indoor dew point of -10°C or below and relative humidity of 10% or less. These systems are increasingly used in EV battery manufacturing facilities, one of the fastest-growing industries
