The Ruidong customizable horizontal air handling unit is a high-efficiency central air conditioning system suitable for a wide range of settings, including office buildings, hotels, shopping malls, hospitals, and schools, providing comfortable indoor air treatment solutions. The unit supports various coil configurations, including 4-row, 6-row, and 8-row arrangements, and can be flexibly configured with chilled water coils or refrigerant coils to meet different heating and cooling load requirements.
The units offer a wide range of airflow capacities, from 2,000 to 65,000 m³/h.
Featuring a double-layer color-coated steel plate structure with high-density polyurethane foam insulation, the units have passed a 2.0 MPa pressure test and exhibit excellent thermal insulation and flame-retardant properties.
Ruidong products are certified under the National Refrigeration Equipment Manufacturing License
and undergo rigorous testing before shipment, ensuring reliable performance.
Ruidong horizontal air handling units are designed with the goals of “customizability, high energy efficiency, and quiet, comfortable operation.” The units come equipped with built-in mesh or bag filters, with optional pre-filters or higher-efficiency filters available. These filters are easy to remove and clean, ensuring clean indoor air.
The units integrate cooling, heating, humidification, dehumidification, and purification functions, adapting to both fresh air and return air conditions to meet diverse HVAC requirements. Equipped with dual-inlet centrifugal fans, the fans undergo dynamic balancing tests to ensure smooth operation and low noise levels; fan bearings use international brands to enhance reliability and service life. The cabinet structure features an aluminum alloy thermal bridge-free frame and double-layer color-coated steel sandwich panels filled with eco-friendly polyurethane foam (optional 25mm/50mm panels, Class B1 flame retardant), providing excellent thermal insulation and corrosion resistance.
The control system offers a choice between PLC or intelligent control modules, enabling coordinated management of air dampers, water valves, and fan motors. It utilizes internationally renowned low-voltage electrical components, ensuring system reliability and ease of maintenance.
The unit features a compact, modular design, supporting customization in size, functionality, and finish, and can be flexibly installed on the floor of a mechanical room or suspended from the ceiling.
