The Dunham Bush Eagle Series is a heavy-duty, light commercial line of air-cooled ducted split air conditioning systems. Delivering nominal cooling capacities from 5 to 20+ Tons, this system pairs the rugged ACCS outdoor condensing unit with a versatile family of indoor air handling units (AHUs): the VEB Series (Vertical Draw-Through), the EB Series (Horizontal Draw-Through), and the HEB Series (High-Static Horizontal Blow-Through). Built around premium scroll compressors and high-volume centrifugal blowers, this commercial split system provides a highly customizable, energy-efficient ducted cooling layout for mid-sized corporate floors, textile garment offices, bank branches, and diagnostic facilities across Bangladesh.
Cooling Capacity from 56 – 1401 MBH (16 – 411 kW)
Heating Capacity from 58 – 1326 MBH (17 – 388 kW)
The ACCS features:
The VEB / EB / HEB features:
The Dunham Bush Eagle Split System is engineered specifically for commercial and industrial buildings where a standard residential split unit is too weak, but a massive central chiller or rooftop packaged plant is structurally impossible or too expensive. Unlike standard packaged systems that require the ductwork to connect directly to the outdoors, a split system separates the refrigeration loop. The heat rejection occurs outside via the ACCS outdoor unit, while the actual cooling, multi-stage air filtration, and indoor air distribution are handled inside by the customized VEB, EB, or HEB indoor sections.
The operational backbone of the Eagle ACCS outdoor unit relies on high-efficiency commercial scroll compressors. These hermetic scrolls run using a continuous, non-contact orbiting mechanism that drastically limits internal friction losses, drops vibration signatures, and keeps operating noise remarkably low. For systems requiring higher tonnage, the compressors are arranged in a staged multi-circuit profile, allowing the plant to scale down its power usage elegantly during evening hours or winter seasons when building heat loads drop.
The indoor section can be customized based on your building's exact layout:
VEB Series (Vertical Floor Standing): Ideal for mechanical closets or corner placements where horizontal ceiling height is restricted.
EB Series (Horizontal Ceiling Suspended): Designed to tuck away cleanly inside false ceiling voids, saving valuable floor space.
HEB Series (High-Static Blow-Through): Specifically built with a heavy-duty belt-driven centrifugal fan system capable of pushing high-velocity air through long, complex sheet metal duct networks.

Customizable Indoors-Outdoors Separation: Isolates heavy, noisy compressor operations on the roof or ground slab while placing space-saving, quiet air handlers directly near the indoor cooling zones.
High-Static Overhead Air Distribution: The HEB air-handling fan package generates excellent static pressure, pushing clean, conditioned air through extensive duct networks to keep large, open-plan spaces uniformly cool.
Multi-Stage Indoor Air Filtration: The indoor sections feature integrated filter tracks that accept high-efficiency air filters, effectively catching dust, fiber particulates, and airborne pollutants.
Proactive Oil Management and Defrost Safeguards: The ACCS outdoor unit includes automated suction line accumulators and oil separators, preventing liquid slugging to ensure the compressor remains well-lubricated during humid operations.
State properties—including regional public bank headquarters, municipal judicial offices, city libraries, and automated telecom data zones—often occupy older or architecturally rigid buildings with strict spatial limitations.
Flexible Structural Integration: Since the indoor units (EB/HEB) can mount directly inside ceiling voids or small utility closets (VEB), public infrastructure projects can add powerful central ducted cooling without tearing down historic walls or reducing usable floor area.
Long-Term Lower Maintenance Costs: Keeping components separated means internal air filters or blower belts can be serviced cleanly indoors without requiring technicians to continuously access high-exposure rooftop zones.
For Bangladesh's ready-made garment (RMG) management floors, modern commercial offices, shopping malls, and private diagnostic laboratories, steady climate control directly drives operational output.
Eliminates Internal Dust in Sewing Offices: Management offices located near active sewing floors face constant challenges from fine fabric dust. The advanced filtration tracks within the Eagle indoor handlers clean the air continuously, protecting computers and creating a healthy workspace.
Scalable Corporate Growth Flexibility: Instead of buying a single massive chiller plant upfront, growing corporate properties can install independent Eagle split loops floor-by-floor as their building occupancy expands.

Q1: What is the main advantage of an Eagle Split System over a standard single Rooftop Packaged Unit?
Ans: A rooftop packaged unit must sit entirely outdoors, requiring large, long vertical duct pathways to enter the building. The Eagle Split System places the air handler inside the building right next to your rooms. This reduces the size of your ductwork, minimizes thermal energy losses along the pipes, and offers greater layout flexibility for multi-story buildings.
Q2: How do I know whether to choose the VEB, EB, or HEB indoor unit for my project?
Ans: It depends on your architectural layout. If you have plenty of ceiling space but zero floor space, choose the horizontal EB or HEB series. If your project features a dedicated mechanical room or utility closet, the vertical floor-standing VEB series is ideal. Our engineering team at Bhai Bhai Engineering will run full spatial assessments to help you choose the best match.
Q3: Can the HEB horizontal indoor unit handle long ducting runs across an open office floor?
Ans: Yes. The HEB series is specifically engineered as a high-static blow-through system. It utilizes high-performance, belt-driven centrifugal fans that can be adjusted on-site to overcome the static friction of extensive sheet metal duct systems, ensuring balanced airflow even to the furthest corners of the room.
Q4: How does the system handle power fluctuations in industrial areas?
Ans: The Dunham Bush Eagle series features built-in safety parameters, including high/low-pressure sensor switches and compressor over-temperature protection. When installed by Bhai Bhai Engineering, we also integrate specialized phase-failure and voltage monitoring relays to safeguard the scroll motors against local grid power sags.
