EKCW 800DA Fan Coil Unit: Horizontal Ductable FCU for Concealed Ceiling Installation

The EKCW-DA 800 is a horizontal water recessed Ductable Fan Coil Unit designed for concealed ceiling installation. It provides efficient cooling and heating with a centrifugal fan, three-speed operation and 75 Pa external static pressure. The unit sits above the false ceiling and connects to ductwork. Conditioned air reaches each room through grilles and diffusers, and the equipment stays out of sight. Its compact design makes it a strong fit for ducted air distribution in residential and commercial spaces.

At Workman Services, we have delivered HVAC&R solutions in Pakistan since 2006. Our scope covers system design, supply, installation, testing, commissioning and maintenance. This guide explains what the EKCW-DA 800 is, how it works and where it performs best. It also includes the full technical specifications and answers to the questions buyers ask most.

What Is the EKCW 800DA Fan Coil Unit?

A fan coil unit (FCU) is an HVAC terminal unit that uses a fan to move air across a water coil. Chilled water cools the air, and hot water heats it. The EKCW-DA 800 is a Ducted Fan Coil Unit. It connects to supply and return ducts instead of blowing air from a visible cabinet in the room.

The unit has a horizontal, recessed layout, so it fits neatly into the ceiling void above offices, shops, hotel rooms and apartments. One unit can serve several outlets through a duct network. This spreads air evenly across a larger area or multiple zones.

In simple terms: the EKCW-DA 800 is a hidden, water-based cooling and heating unit. It connects to ducts and delivers up to 805 CFM of conditioned air through ceiling diffusers.

How It Differs From Cassette and Exposed Units

A 4-way cassette AC mounts flush with the ceiling, and its panel stays visible in the room. An exposed FCU sits on the wall or floor. The EKCW-DA 800 keeps the entire unit above the ceiling, and only the grilles show. That makes it a popular choice for projects where interior design, clean ceilings and flexible air distribution matter.

How a Ceiling Concealed FCU Works in a Water-Based HVAC System

The EKCW-DA 800 follows a simple and proven operating cycle:

1. Water supply: Chilled water for cooling or hot water for heating flows from the central plant into the copper tube coil. The rated water flow is 0.63 m³/h, with a water pressure drop of 10 kPa.
2. Air intake: A centrifugal forward-curved fan, driven directly by a 3-speed motor, draws return air from the space.
3. Heat exchange: Air passes over the coil, where copper tubes and hydrophilic aluminum fins transfer heat between the air and the water.
4. Condensate removal: Moisture removed from the air during cooling drains away through the Rc3/4 condensate connection.
5. Air delivery: The fan pushes conditioned air through the ductwork against 75 Pa of external static pressure and into the rooms through diffusers.
6. Speed control: Users or building controls choose high, medium or low fan speed to match the cooling or heating demand.

Mini summary: The unit turns water from a central plant into comfortable supply air. It then sends that air through ducts to the rooms it serves.

Key Features and Benefits of the EKCW-DA 800

Why the EKCW 800DA Fan Coil Unit Works for Commercial Projects

• 6.59 kW nominal cooling capacity for dependable comfort in medium-sized spaces
• 12.71 kW nominal heating capacity for strong winter performance on hot water systems
• High airflow performance up to 805 CFM for good air distribution through ducted outlets
• 75 Pa external static pressure to push air through duct runs, grilles and diffusers
• 40–100 Pa ESP application range for flexibility across different duct layouts
• Three-speed fan operation with 805, 762 and 641 CFM airflow settings
• Copper tube coil with hydrophilic aluminum fins for reliable heat transfer
• Suitable for concealed ducted installation that keeps interiors clean and uncluttered
• Designed for low-noise operation and easy maintenance

Quiet Performance for Occupied Spaces

The EKCW-DA 800 has a rated sound pressure of 48.7 dB(A). The unit sits above the ceiling, and air reaches the room through ductwork. This setup helps keep equipment noise away from people working, resting or shopping below.

Modest Electrical Demand

At high speed, the unit’s rated power is 297 W with a rated current of 1.44 A. It runs on a 220–240V, single-phase, 50Hz supply. That matches standard single-phase power in Pakistan, which keeps electrical planning simple for most buildings.

Where Is the EKCW-DA 800 Used? Applications in Pakistan

Across Lahore, Rawalpindi, Faisalabad and other cities, commercial plazas, malls and hospitals often rely on chilled water systems. A Ceiling Concealed FCU like the EKCW-DA 800 fits these projects well. It delivers comfort without taking up floor or wall space.

How to Choose the Right Ductable Fan Coil Unit for Your Project

Choosing the right unit takes more than matching a capacity number. Check these six factors before you finalize your selection:

1. Cooling and heating load: Match the room’s calculated load to the unit’s 6.59 kW cooling and 12.71 kW heating capacity. In refrigeration tons, 6.59 kW equals roughly 1.87 TR.
2. Duct design: Make sure the total duct resistance falls within the 40–100 Pa ESP range. Long duct runs or many outlets add resistance.
3. Airflow per zone: Plan diffuser sizes and locations around the 641–805 CFM airflow range.
4. Water-side compatibility: Confirm that your chilled or hot water system can supply 0.63 m³/h at a 10 kPa pressure drop.
5. Ceiling space and access: Leave room above the ceiling for the unit, the ducts, the pipework and a sloped condensate line. Add access panels for routine service.
6. Electrical supply: Provide a 220–240V, single-phase, 50Hz connection at each unit location.

If your project needs a Ducted Fan Coil Unit as part of a larger chilled water system, our engineers can help with load calculations, duct design and equipment selection.

Mini summary: The right fan coil choice depends on load, duct resistance, water flow and installation space, not just the capacity on the label.

Frequently Asked Questions

What is the cooling capacity of the EKCW-DA 800?

The EKCW-DA 800 has a nominal cooling capacity of 6.59 kW, which is roughly 1.87 TR. It also provides 12.71 kW of nominal heating capacity when connected to a hot water supply.

What is the difference between a Ducted Fan Coil Unit and a Ductable Fan Coil Unit?

The two terms are usually used interchangeably. Both describe a fan coil designed to connect to ductwork, with enough external static pressure to push air through ducts. The EKCW-DA 800 offers 75 Pa ESP, with an application range of 40–100 Pa.

Where is the EKCW-DA 800 installed?

It is installed horizontally in the ceiling void, above a false ceiling. Ducts carry conditioned air from the unit to grilles and diffusers in the rooms below. This makes it a true Ceiling Concealed FCU, because no equipment appears in the occupied space.

How much airflow does the unit deliver?

The unit delivers 805 CFM at high speed, 762 CFM at medium speed and 641 CFM at low speed. The three-speed motor lets you match airflow to changing comfort needs.

How noisy is the EKCW-DA 800?

The rated sound pressure is 48.7 dB(A). Because the unit sits above the ceiling and supplies air through ducts, it suits offices, hotels, hospitals and homes where quiet operation matters.

What power supply does it need?

It runs on a 220–240V, single-phase, 50Hz supply. The rated power at high speed is 297 W, with a rated current of 1.44 A.

Does the EKCW-DA 800 need a chiller?

Yes. It is a water-based unit, so it needs chilled water for cooling and hot water for heating from a central plant. Workman Services supplies chillers and complete chilled water system solutions as well.

Is the unit easy to maintain?

The unit is designed for easy maintenance. Plan ceiling access panels during installation so technicians can reach the unit for routine checks of the filters, the coil and the condensate drain.
