Self Drainage 4 Way Cassette Fan Coil Unit Ceiling Mount HVAC

Self-Drainage 4 Way Cassette Fan Coil Unit

The Self-Drainage 4 Way Cassette Fan Coil Unit is a ceiling-mounted HVAC terminal designed for hot and chilled water air conditioning systems. Its self-drainage structure eliminates the need for a built-in drain pump, providing a simpler condensate drainage solution with fewer mechanical components.

Combined with a high-efficiency copper-aluminum coil, balanced low-noise fan, ABS cassette panel, and flexible thermostat control, it is suitable for residential, commercial, and light-duty HVAC applications.

Key Features

Self-Drainage Without Built-In Pump

Unlike conventional cassette fan coil units equipped with a condensate pump, this model uses a natural drainage design to discharge condensate water.

The simplified drainage structure helps reduce mechanical components inside the unit and makes routine maintenance easier.

Benefits:

1.  No built-in drain pump
2.  Natural condensate drainage
3.  Simplified internal structure
4.  Lower maintenance requirements
5.  Suitable for ceiling-mounted installation

High-Flow Condensate Drainage

The specially designed drain pan provides an effective drainage path for condensate generated during cooling operation.

Its high drainage drop helps accelerate water discharge and supports stable operation of the ceiling-mounted unit.

Flexible Thermostat Control

The unit is supplied without a standard remote controller, allowing the control configuration to be selected according to the HVAC project.

It can be connected to an external thermostat, while remote control can be added when the corresponding PCB configuration is installed.

Efficient Copper-Aluminum Coil

The heat exchanger uses copper tubes and high-surface-area aluminum fins to provide efficient heat transfer between water and air.

Each coil is tested at 30 bar (3 MPa) to verify leakage resistance before delivery.

The coil configuration includes:

1. Copper heat exchange tubes
2. Aluminum fins
3. 3/4" pipe connections
4. Air bleed vent
5. 100% pressure leak testing

Quiet & Stable Airflow

The fan wheel is produced through one-piece injection molding to achieve consistent geometry and good dynamic balance.

An anti-vibration rubber component is incorporated into the fan hub to help reduce vibration during operation.

Fan system features:

1. G0.5mm/s fan wheel balancing
2. Anti-vibration construction
3. Low operating noise
4. Smooth airflow delivery
5. Stable motor operation

Modern 4-Way Cassette Panel

The ABS cassette panel provides a clean ceiling appearance while distributing conditioned air through four outlets.

The washable and removable filter allows convenient routine cleaning.

Panel features:

1. ABS construction
2. Four-way air distribution
3. Washable air filter
4. Removable filter design
5. Manual louver adjustment
6. Auto-swing function

Simplified Design for Easier Maintenance

The absence of a built-in drain pump gives the unit a simpler condensate management structure.

For applications where natural drainage is available, this configuration can reduce the number of moving components and simplify inspection and maintenance.

It is particularly suitable for projects that prioritize simple construction, reliable drainage, and easy long-term servicing.

Applications

The Self-Drainage 4 Way Cassette Fan Coil Unit can be integrated into hot and chilled water HVAC systems for:

1. Residential buildings
2. Apartments and villas
3. Hotels
4. Offices
5. Restaurants
6. Retail spaces
7. Commercial buildings
8. Other ceiling-mounted HVAC projects

Product Advantages
