Description

Haier HBU-48E/DC 4 Ton DC Inverter Ceiling Cassette AC

The Haier HBU-48E/DC 4 Ton DC Inverter Ceiling Cassette AC is designed for large commercial and professional spaces that require high cooling capacity, wide air distribution and a ceiling-mounted installation. Haier officially categorizes this model as a 4 Ton DC Inverter Heat & Cool cassette AC, making it suitable for offices, showrooms, restaurants, conference rooms and other large indoor areas.

4 Ton DC Inverter Performance

The HBU-48E/DC provides powerful inverter climate control with a rated 14.1 kW cooling capacity and 14 kW heating capacity.

Its DC inverter system adjusts compressor operation according to cooling or heating demand rather than relying only on fixed-speed on/off cycles, helping maintain more controlled indoor temperatures during extended use.

14.1 kW Cooling Capacity

Haier officially specifies 14.1 kW cooling capacity, equivalent to approximately 48,000 BTU/h.

This high output places the HBU-48E/DC in the 4 Ton category and makes it suitable for large commercial spaces where smaller residential AC capacities may not be sufficient.

Heat & Cool Operation

The Haier HBU-48E/DC supports both cooling and heating, allowing year-round operation.

Official capacities include:

• Cooling Capacity: 14.1 kW
• Heating Capacity: 14 kW

This makes it useful for commercial areas that require climate control in both summer and winter.

Round-Way Air Flow

Haier highlights Round Way Air Flow for this cassette model.

The ceiling-mounted cassette design distributes conditioned air in multiple directions from a central position, helping achieve broader coverage across large or open-plan spaces compared with conventional wall-mounted airflow.

2,050 m³/h High Airflow

Haier specifies an airflow volume of 2,050 m³/h on high setting.

This strong airflow supports faster and more even distribution of conditioned air throughout larger rooms, offices, showrooms and other high-occupancy spaces.

T3 High-Ambient Design

The HBU-48E/DC features High Ambient Design (T3).

Haier’s commercial cassette information states that its T3 outdoor system is designed to continue cooling operation when outside temperatures reach up to 52°C, making this feature particularly relevant for demanding Pakistani summer conditions.

Three-Phase Power Supply

Unlike typical domestic split ACs, the HBU-48E/DC requires a 3 Phase, 380V, 50Hz power supply.

This is an important installation requirement and should be confirmed at the site before purchase.

Cooling & Heating Power Input

Haier officially specifies:

• Cooling Rated Power Input: 4.4 kW
• Heating Rated Power Input: 4.3 kW

Actual electricity consumption will vary according to operating load, temperature setting, insulation, occupancy, ambient conditions and installation quality.

R410A Refrigerant

The HBU-48E/DC uses R410A refrigerant.

Haier specifies the following refrigerant pipe sizes:

• Liquid Pipe: 9.52 mm
• Gas Pipe: 19.05 mm

These specifications should be considered during professional installation and piping planning.

Ceiling Cassette Installation

A ceiling cassette AC is particularly useful where users want strong climate control without occupying wall or floor space.

Typical applications include:

• Corporate offices
• Large meeting rooms
• Retail showrooms
• Restaurants
• Commercial halls
• Clinics and waiting areas
• Open-plan workspaces

The installation requires suitable ceiling space and should be carried out by a qualified professional.

Built-In Drain Pump

Haier’s 4-way cassette platform includes a built-in high-head drain pump, which helps remove condensate water and gives installers additional flexibility when routing drainage within a ceiling installation.

Long Pipe Length

Haier lists Long Pipe Length among the official features of the HBU-48E/DC.

This can provide greater installation flexibility when the indoor and outdoor units cannot be positioned close together, subject to Haier’s installation limits and professional setup requirements.
