Product Overview
Direct Expansion Air Handling Units are self-contained, DX coil-equipped air handling solutions designed for applications where chilled water systems are not available or where independent cooling is preferred. The AHU-DX Series integrates direct expansion cooling coils directly into the air handling unit, eliminating the need for a separate chilled water plant and associated piping - delivering a complete, self-contained air conditioning system in a single package.
The series supports both mixed air condition and fresh air condition applications, with airflow capacities ranging from 2,750 to 59,300 m³/h for mixed air and 2,500 to 12,400 m³/h for 100% fresh air. Static pressure options from 300 to 500 Pa ensure compatibility with various ductwork configurations, making the AHU-DX Series suitable for a wide range of commercial and industrial applications where independent, refrigerant-based cooling is required.
Core Features
Self-Contained Direct Expansion Configuration
The integrated DX coil design eliminates the need for chilled water systems, cooling towers, and associated water treatment equipment. Each unit is a complete, self-contained air conditioning system that requires only electrical power and refrigerant piping connections, significantly simplifying installation and reducing initial investment costs.
Mixed Air & Fresh Air Condition Options
Available in both mixed air condition and fresh air condition configurations to suit different application requirements. Mixed air condition units handle recirculated air with fresh air mixing for energy-efficient ventilation, while fresh air condition units process 100% outdoor air for dedicated ventilation applications requiring complete air changes.
Customizable Heat Recovery Options
Optional rotary heat exchanger and plate heat exchanger configurations available to capture waste energy from exhaust air and transfer it to incoming fresh air. This significantly reduces heating and cooling loads, improving overall system energy efficiency and reducing operational costs in ventilation-intensive applications.
Flexible Installation - Indoor & Outdoor
Supports both indoor and outdoor installation configurations to accommodate diverse site conditions. Indoor units are designed for equipment room installation, while outdoor units feature weather-resistant construction for rooftop or exterior placement. This flexibility ensures seamless integration regardless of available space.
Optimized Static Pressure Range
Static pressure options from 300 to 500 Pa provide the flexibility to overcome ductwork resistance in medium to long air distribution systems. This ensures adequate airflow delivery even with extended duct runs, diffusers, and other air distribution components.
Rugged Construction for Dependable Operation
Built with robust construction and quality components to ensure reliable operation in demanding environments. The design incorporates corrosion-resistant materials and protective finishes to withstand the rigors of continuous operation.
