Horizontal Air Handling Unit for Commercial HVAC Systems
Product Overview
As a premium horizontal air handling unit, the REF-5WC-100-4R-L is designed to deliver exceptional air quality and thermal comfort while optimizing installation space. This ceiling-mounted AHU features a robust cabinet structure, a 4-row chilled water coil, a 10,000 m³/h air volume capacity, and a left-hand water connection. Equipped with double-inlet centrifugal fans, this air handling unit guarantees quiet operation, high efficiency, and long-lasting durability. Its low-profile horizontal design provides a highly efficient horizontal AC solution for mechanical rooms with limited floor space in modern central air conditioning systems.
Key Features
🦠 Nano TiO2 Air Sterilizer
Optional Nano-scale TiO2 healthy air sterilizer effectively removes bacteria, viruses, VOCs, and unpleasant odors, ensuring a safe and clean indoor environment for your AHU system.
🌀 High-Efficiency Centrifugal Fan
Utilizes double-inlet multi-wing centrifugal fans, dynamically and statically balanced to guarantee low noise, high airflow, and stable operation of the air handling unit even at high external static pressures.
❄️ Premium Coil Design
Aluminum fins and copper tubes are mechanically expanded for tight contact. Tested at 2.4MPa for air tightness, ensuring optimal heat transfer efficiency and long-term durability.
🛡️ Space-Saving Horizontal Frame
High-strength aluminum alloy frame with polyurethane foam insulation. The compact horizontal AC design saves floor area and fits perfectly in ceiling voids, while double-skin panels ensure excellent thermal insulation.
Application Scenarios
Our 5W series horizontal AHU is widely used in commercial and industrial environments where ceiling installation is required and floor space is limited.
Commercial Buildings
Ideal for ceiling voids in office buildings and shopping malls, providing stable temperature control and excellent indoor air quality without occupying valuable floor space.
Hotels & Hospitals
With the Nano TiO2 sterilizer, it ensures hygienic and comfortable air. The horizontal design is perfect for concealed installation in ceiling plenums of hotels and hospitals.
Theaters & Large Venues
Capable of handling large air volumes (10,000 m³/h) quietly. The compact horizontal AC unit can be conveniently installed in ceiling spaces or utility corridors.
Industrial Plants
Robust construction and customizable configurations make this AHU highly reliable for factory workshops, easily adapting to overhead ductwork layouts.
Frequently Asked Questions
What is the difference between an AHU and a standard horizontal AC?
A standard horizontal AC (air conditioner) is typically designed for direct space cooling. An AHU (air handling unit) like this model is a more complex, heavy-duty system that conditions and circulates air through ductwork, offering customizable cooling coils, filtration, and higher external static pressures for large commercial spaces.
What are the main advantages of this horizontal air handling unit?
Unlike vertical floor-standing units, this horizontal AHU is designed for ceiling suspension. It completely frees up valuable floor space and is particularly suitable for buildings with limited mechanical room areas but adequate ceiling height.
What is the cooling capacity of this AHU under return air and fresh air conditions?
Under the return air condition (27/19 °C) the cooling capacity is 61.0 kW, while under the fresh air condition (34 °C dry-bulb / 28 °C wet-bulb) it reaches 131.0 kW. Both ratings are based on 7/12 °C chilled water supply and return temperatures.
Is the Nano TiO2 air sterilizer included?
The Nano TiO2 healthy air sterilizer is an optional accessory. It can be integrated into this horizontal air handling unit to remove bacteria, viruses, and odors. Please specify this requirement when ordering.
Can the connection direction and coil rows be customized?
Yes. We can customize the AHU to meet specific requirements for airflow, coil rows (4, 6, or 8 rows), and connection directions (left or right) to perfectly match your project design.
