Haier HSU-48 4 Ton Fixed Speed Cassette Type LCAC Air Conditioner (AC)

Product Description

Too large for standard AC? Haier HSU-48 4 Ton Cassette fits!

Large commercial spaces demand more than a wall-mounted unit can deliver. The Haier HSU-48 4 Ton Fixed Speed Cassette Type LCAC Air Conditioner handles 48,000 BTU/h of cooling capacity — purpose-built for open-plan offices, retail floors, restaurants, and server-adjacent rooms where consistent, distributed airflow is non-negotiable. Check the AC Price in Bangladesh for this cassette AC that makes a direct case for uneven cooling, high energy bills, or inadequate coverage solutions.

PCB Store brings this heavy-duty air conditioner with the best Haier Latest AC Price to buyers across Bangladesh, meeting the demand for high-capacity ceiling-mounted cooling in both commercial and large residential installations.

Haier HSU-48 Specs and Cooling Performance Overview

The HSU-48 runs on a 3-phase power supply at 380–415V/50Hz, drawing 4,550W of power input during cooling. Its EER rating of 3.1 places it in a competent efficiency bracket for fixed-speed commercial units. Running current sits at 7.33A, which is well within safe operational parameters for commercial electrical infrastructure.

The indoor unit measures 840×840×288mm and weighs 27kg. The outdoor unit is considerably larger at 950×370×1350mm with a net weight of 91kg, reflecting the heavy-duty compressor and heat exchanger assembly required for 4-ton output. The system uses R32 refrigerant — a lower global warming potential (GWP) refrigerant that is increasingly the standard in modern Home applience systems.

Refrigerant pipe connections use a 9.52mm liquid side and 15.88mm gas side diameter, standard for large-capacity cassette systems.

Key Features That Set the HSU-48 Apart

The Haier HSU-48 is not just a large-capacity unit — it is a feature-dense system designed for real-world installation challenges and occupant comfort. The DC Fan Motor reduces motor energy loss and operates more quietly compared to conventional AC fan motors. Pair this with the Brand New Designed Fan and Large Heat Exchanger Design, and you get a system that moves air efficiently without generating excessive heat buildup in the outdoor unit.

The Round Way Air Supply distributes conditioned air in four directions simultaneously from the ceiling-mounted panel. This eliminates cold and warm zones in large rooms — a persistent complaint with directional wall units. The Automatic Airflow Control adjusts distribution based on demand, and the Individual Flap Control lets you manually direct airflow to specific zones when needed.

For spaces with high ceilings — warehouses, banquet halls, or double-height commercial lobbies — the Haier HSU-36 3 Ton Fixed Speed Cassette Type LCAC Air Conditioner High Ceiling Mode is a critical advantage. Standard cassette units lose efficiency projecting cool air downward over long distances. The HSU-48's airflow settings account for this, with four fan speeds (Hi/Mid/Lo/Super Low) at 2170, 2010, 1730, and 1450 m³/h respectively.

The Hidden LED Display maintains a clean, unobtrusive ceiling aesthetic while still providing operational feedback. Paired with the Haier HSU-30 2.5 Ton Fixed Speed Cassette Type LCAC Air Conditioner Super Big Inlet Grille, the unit draws return air more effectively, reducing the strain on the system during peak load.

Noise, Drainage, and Practical Installation Details

Sound performance is a real concern in commercial environments. The indoor unit operates at 54/51/48/44 dB(A) across its Hi/Mid/Lo/Super Low settings. The outdoor unit maintains a consistent 60 dB(A). These are not library-quiet figures, but they are appropriate for commercial settings where ambient noise already exists.

The High Lift-up Drain Pump addresses one of the most common cassette AC installation limitations — drainage. Many installations cannot route condensate by gravity alone. The built-in drain pump lifts condensate to appropriate drainage points, expanding where this unit can realistically be installed without civil works.

The Convenient Filters are accessible from below the panel, simplifying routine maintenance. No ladders or panel removal are required for filter cleaning, which matters in high-ceiling installations where maintenance access is already a logistical challenge. The Installation Friendly design extends this philosophy to refrigerant routing and mounting — reducing labor time during setup.

The separate panel (Model PB-950QB) measures 950×950×50mm at 5.5kg net weight, fitting cleanly into standard commercial ceiling tile grids while projecting minimal visual bulk downward.

Compatibility and Ideal Use Cases

Here's the text with a mix of prose and bullet points:

The Haier HSU-48 is designed for spaces roughly between 150 to 220 square meters depending on ceiling height, insulation quality, and heat load. It is best suited for:

• Open-plan offices and medium-sized retail stores
• Hotel lobbies, restaurants, and meeting halls
• Light industrial spaces with stable ambient conditions

The 3-phase power requirement means this unit is not compatible with standard single-phase residential wiring. Buildings must have a 3-phase 380–415V/50Hz supply available at the installation point — a standard configuration in commercial properties across Bangladesh, but worth confirming before purchase.

The R32 refrigerant system is compatible with R32-certified installation tools and recovery equipment. Any licensed HVAC technician in Bangladesh familiar with commercial cassette systems will have the required tooling.

As a fixed-speed system, the compressor runs at a constant capacity when active. This makes it best suited for:

• Spaces that require sustained, high-output cooling
• Environments with consistent heat loads rather than variable demand
• Situations where an inverter system's efficiency gains would be minimal

Reliability and Brand Assurance

Haier is one of the largest [air conditioner](internal link) manufacturers globally, and its commercial LCAC range reflects years of engineering refinement for high-load applications. The rotary compressor type used in the HSU-48 is known for durability in sustained-use scenarios — a critical factor for commercial buyers who run their systems 8–12 hours daily.

The Large Heat Exchanger Design directly contributes to long-term reliability by reducing head pressure and thermal stress on the compressor. Energy Saving mode optimizes fan and flap operation during lower-demand periods, extending component lifespan beyond what full-load continuous operation would produce.

Haier products sold through authorized channels in Bangladesh come with manufacturer warranty support. PCB Store, as an authorized [home appliance](internal link) retailer, provides purchase documentation necessary for warranty claims — a non-trivial benefit when dealing with commercial-grade equipment where after-sales support directly impacts business continuity.
