Dual discharge coolers distribute cold air from both sides of the unit, providing even temperature distribution across the storage area. The DDS range is optimised for smaller cold rooms where short air throw distances are required, while the DDL range delivers longer air throws for larger storage areas. Both ranges are available with DX refrigerant or secondary glycol cooling mediums, with EC fan options and easy-clean specifications for food-grade applications. ### High-Quality Construction All HC Coils Industrial Air Coolers are manufactured using premium materials and precision engineering to ensure maximum efficiency and long-term reliability. Standard construction features include: - High-efficiency copper tube and aluminium fin coils - Mechanically bonded tube-to-fin construction for maximum heat transfer - Heavy-duty galvanised steel casing with powder-coated finish - Energy-efficient axial fan assemblies - Industrial-grade fan motors for continuous operation - Hinged drip trays for easy maintenance access - Corrosion-resistant construction options available - Integrated defrost heater arrangements where required Our robust construction ensures dependable performance in demanding industrial refrigeration environments. ### Energy Efficient Cooling Performance Each Industrial Air Cooler is optimised using advanced selection software to ensure: - Maximum cooling efficiency - Reduced energy consumption - Uniform air distribution - Low pressure drop - Quiet operation - Precise performance matching to your application We offer advanced fan and control technologies including: - EC variable speed fan motors - Low noise fan options - Fan speed control systems - Energy-saving motor technology - Intelligent temperature management Our EC fan options significantly reduce power consumption while maintaining consistent cooling performance. ![Bespoke HC Coils dual discharge unit cooler with twin coil banks and white powder-coated casing](/assets/dual-discharge-unit-LZOgHAXs.jpg) ### Key Advantages - **Improved airflow coverage —** dual discharge distributes air evenly across the storage area. - **Enhanced temperature uniformity —** consistent conditions throughout the cold room. - **Efficient cooling performance —** optimised coil and fan design for reliable output. - **Reduced air stratification —** balanced flow prevents warm and cold layers forming. - **Energy-efficient operation —** EC fan options minimise running costs. ### Optional Features **Fans** — EC fans, low noise AC fans, defrost socks. **Easy Clean** — hinged fan plates and fan isolators for fast access. **Fins** — Aluminium, poly coated Aluminium, Copper, tinned Copper, or specialist coatings (Blygold, Bronzeglow, Heresite). **Defrost** — electric, hot gas or warm glycol. **Casework** — plain galvanised, powder coated galvanised, or 304L stainless watchcase. **Bespoke** — further options available for bespoke designs. Typical Applications Food Processing Cold Storage Blast Freezing Process Cooling Industrial Warehouses ![DDL dual discharge cooler installed in a chilled produce storage warehouse](/assets/dual-discharge-coldroom-DT0qXy_b.jpg)![Underside view of a dual discharge cooler showing multiple EC fans](/assets/dual-discharge-fans-underside-CueEYMCM.jpg)![Bespoke dual discharge cooler coils stacked on the HC Coils factory floor](/assets/dual-discharge-coils-stacked-C25Ikc4X.jpg) [Get Engineering Advice on Dual Discharge Unit Coolers (DDS/DDL)]() Downloads Product Catalogue Full specifications, dimensions and performance data.
