Overview

Central Station Air Handler is a type of air handling unit (AHU) designed for medium to large commercial or institutional buildings. It is typically located in a mechanical room, equipment mezzanine, or rooftop space and serves as the central point for managing airflow, ventilation, and indoor air quality throughout the facility.

These units are modular or custom-built to meet the specific airflow, thermal load, and filtration requirements of the building.

Key Features of Industrial AHUs

◆Customizable Configurations
Central station air handlers are often built-to-order, allowing flexible component selection based on project specifications.

◆High Air Volume Capacity
Capable of handling large volumes of air (thousands of CFM), making them suitable for large zones or entire buildings.

◆Integrated Components
Typically include supply and return fans, filters, heating/cooling coils, humidifiers, dampers, and controls within a single housing.

◆Indoor or Outdoor Installation
Designed for both indoor mechanical rooms and weather-resistant rooftop applications.

Applications of Industrial AHUs

Factories and Manufacturing: Provide proper ventilation, cooling, and heating for production lines, workshops, and processing areas.
Warehousing and Logistics Centers: Ensure temperature and humidity control in storage areas to maintain the quality and shelf life of goods.
Chemical and Hazardous Materials Handling: Provide air purification and explosion-proof capabilities to ensure the safety and stability of working environments.
Food Processing and Manufacturing: Deliver clean air environments for food production facilities to ensure food safety and quality.
Pharmaceutical Manufacturing and Laboratories: Provide strict temperature, humidity, and cleanliness control for pharmaceutical factories and laboratories to meet stringent requirements for drug production.

Blower:Blower bearings use lubricated precision ball bearings, and the outer seal ring of the bearing is made of polyamide rubber, which is resistant to high temperatures and can absorb vibration and mechanism noise. The impeller of the purification series air conditioner fan is made of high-quality steel plate (backward-inclined impeller is configured as required), which is more in line with the specific shape of aerodynamics, with high efficiency and low noise.

Surface cooler: The copper tube and aluminum sheet structure is adopted. The copper tube and aluminum sheet are tightly combimechanical or water pressure expansion, and tested by 1.6Mpa air pressure to ensure the minimum contact thermal resistance to achieve the best heat transfer effect. The condensate tray is made of high-quality steel plate or SUS304, double-layer filled with polyurethane foam, and the slope design is more conducive to the discharge of condensate, which has obtained the national patent

Filter: Primary, medium and high efficiency filtration sections are equipped with differential pressure gauges to monitor the initial and final resistance of the filter, providing a scientific basis for filter replacement. Primary, medium and high efficiency filters, as well as photohydrogen ion, high voltage electrostatic and electronic purification filters can be configured according to requirements.
