Daikin FXZQ25A VRV Fully Flat Cassette Indoor Unit – 2.8 kW

Daikin FXZQ25A VRV indoor unit

The Daikin FXZQ25A is a compact fully flat cassette indoor unit designed for compatible Daikin VRV air-conditioning systems.

The unit provides a nominal 2.8 kW cooling capacity and 3.2 kW heating capacity, making it suitable for appropriately sized rooms and zones within compatible commercial VRV installations.

The FXZQ-A range is designed to integrate closely with architectural ceiling layouts, making it a strong choice for offices, hotels, retail environments and other commercial spaces where appearance and efficient use of ceiling space are important.

Daikin FXZQ25A VRV Indoor Unit

The FXZQ25A belongs to Daikin’s FXZQ-A Fully Flat Cassette range.

Daikin describes this range as a fully flat cassette designed to integrate into standard architectural ceiling tiles, leaving only a small amount of the unit visible below the ceiling.

This makes the FXZQ25A particularly suitable where customers want commercial air conditioning that blends into the interior rather than occupying valuable wall or floor space.

2.8 kW Cooling Capacity

The Daikin FXZQ25A provides 2.8 kW nominal cooling capacity.

This capacity can be suitable for appropriately sized rooms or zones within a compatible VRV system.

Actual system sizing should be determined from the property’s cooling load rather than room area alone.

Important factors include:

• Room dimensions
• Insulation
• Window area
• Solar exposure
• Occupancy
• Lighting
• Equipment heat loads
• Building orientation
• Local climate

3.2 kW Heating Capacity

The FXZQ25A also provides 3.2 kW nominal heating capacity.

When connected to an appropriate compatible VRV heat-pump system, the indoor unit can therefore provide both heating and cooling.

This makes the FXZQ25A suitable for year-round commercial climate control where the complete VRV system supports the required operating modes.

Fully Flat Cassette Design

The defining feature of the FXZQ25A is its fully flat cassette design.

Daikin states that the FXZQ-A integrates into standard architectural ceiling tiles, with only approximately 8 mm extending from the ceiling.

This creates a clean appearance suitable for modern commercial interiors.

Benefits of the fully flat design include:

• Discreet ceiling integration
• Minimal visual impact
• No occupied wall space
• No occupied floor space
• Suitable for modern office interiors
• Suitable for hotel interiors
• Suitable for retail environments
• Flexible architectural integration

Intelligent Airflow Control

Daikin’s Fully Flat Cassette range includes individual flap control, allowing airflow patterns to be adjusted according to the room layout.

This can be useful in rooms with:

• Corner installations
• Adjacent walls
• Irregular layouts
• Different furniture arrangements
• Changing interior configurations

The airflow direction can be adjusted without relocating the indoor unit.

Optional Intelligent Sensors

Compatible FXZQ-A configurations can use optional intelligent sensors.

Daikin describes a presence sensor that can detect people and adjust airflow to reduce direct drafts, while an optional floor sensor helps maintain more consistent temperatures between floor and ceiling levels.

These features are optional, so your product page should say “available on compatible configurations” rather than implying that every sensor is automatically included.

Quiet Commercial Air Conditioning

The FXZQ-A range is designed for quiet operation.

Daikin describes the Fully Flat Cassette as capable of operating at sound levels as low as 25 dBA on applicable models and settings.

For the exact FXZQ25A configuration, use the sound-pressure figure from the technical documentation supplied with your particular model rather than automatically applying the lowest range figure.

Compact Ceiling Installation

Daikin’s technical documentation lists the FXZQ-A indoor-unit dimensions at approximately:

260 mm H × 575 mm W × 575 mm D

for the relevant 20/25 class units.

This compact ceiling footprint makes the unit suitable for installations based around compatible architectural ceiling modules.

Ceiling Integration

The FXZQ-A is designed around the 600 × 600 mm ceiling-module concept.

The cassette can therefore be incorporated into suitable suspended-ceiling layouts while maintaining a discreet appearance.

Daikin lists compatible decoration panels, including white and silver options, depending on configuration.

Important: Only state that a decoration panel is included if your EuroFuelSupply package actually includes one.

Airflow Performance

For the FXZQ25A class, Daikin documentation lists approximately:

• 6.5 m³/min low fan
• 9.0 m³/min high fan

for cooling operation under the specified test conditions.

Actual airflow depends on fan speed and operating conditions.

Daikin VRV Compatibility

The FXZQ25A is a VRV indoor unit, not a complete standalone air conditioner.

It must be connected to a compatible Daikin VRV outdoor unit and control system.

Before purchasing, the installer should verify:

• VRV outdoor-unit compatibility
• Indoor-unit combination
• Refrigerant piping
• Control requirements
• Electrical requirements
• Condensate drainage
• Ceiling construction
• Decoration-panel requirements
• System commissioning requirements

This is particularly important for replacement orders.

Commercial Applications

The Daikin FXZQ25A can be incorporated into suitable commercial VRV installations.

Offices

The fully flat ceiling design can complement modern office interiors.

Hotels

The discreet cassette design is suitable for appropriately sized hotel rooms and commercial spaces.

Retail

The ceiling-mounted configuration preserves valuable wall and floor space.

Meeting Rooms

The unit can provide heating and cooling for appropriately sized meeting spaces.

Commercial Buildings

Multiple compatible VRV indoor units can form part of a larger centralized climate-control system.

Daikin positions VRV as a building climate-control solution with multi-zone control and a broad selection of indoor-unit types.
