4 Pipe 4 Way Cassette Fan Coil Unit
The 4 Pipe 4 Way Cassette Fan Coil Unit is a ceiling-integrated HVAC terminal designed for buildings that require flexible heating and cooling control. Its four-pipe configuration provides separate hot and chilled water circuits, while the four-way air outlet helps distribute conditioned air evenly throughout the room.
Designed with a high-efficiency copper-aluminum coil, low-vibration fan assembly, integrated condensate protection, and flexible control options, the unit is suitable for hotels, offices, apartments, commercial buildings, and other multi-zone HVAC projects.
Key Features
Independent Heating & Cooling Circuits
The 4-pipe configuration uses separate connections for hot water and chilled water, providing greater flexibility for zone-level temperature management.
It is particularly suitable for buildings where different rooms or areas may require heating and cooling according to individual comfort requirements.
Four-Way Air Distribution
The cassette panel distributes conditioned air in four directions to help create a more uniform indoor temperature.
The ceiling-mounted structure keeps the unit integrated into the interior while reducing the need for occupied wall or floor space.
High-Efficiency Heat Exchange Coil
The heat exchanger combines copper tubes with high-surface-area aluminum fins to promote efficient heat transfer.
Every coil undergoes pressure testing to help ensure reliable performance and reduce the possibility of leakage during operation.
Low-Noise Fan Design
The fan wheel is manufactured using precision injection molding to maintain consistent geometry and balance.
An anti-vibration structure helps reduce mechanical vibration between the fan and motor, supporting quieter and smoother operation in indoor environments.
Reliable Condensate Management
The unit includes an integrated drain pump with check valve and float switch.
The float switch monitors the condensate level and can trigger an alarm and protective operation if the water level becomes excessive, helping reduce the risk of ceiling leakage.
Multiple Control Options
The fan coil can be integrated into different building control systems through multiple control configurations:
- Remote controller — Standard
- RS485 master-slave control — Standard
- Wired controller — Optional
- WiFi connection — Optional
- Multi-unit control for centralized management
Optional Fresh Air Intake
A fresh air intake option is available for projects requiring additional ventilation or fresh-air integration.
Designed for Flexible HVAC Zoning
Unlike a conventional two-pipe fan coil arrangement, the 4 Pipe 4 Way Cassette Fan Coil Unit provides separate hot and chilled water circuits.
This configuration offers greater flexibility for multi-zone buildings and is well suited to projects where different indoor areas have different thermal requirements.
Compact Ceiling-Mounted Design
The unit body is constructed from galvanized steel with insulated internal air passages.
The insulated EPS air passage structure helps improve thermal and acoustic insulation while providing a defined airflow path.
The ABS decorative panel incorporates a washable and removable filter, while the auto-swing function assists with wider air distribution.
The compact cassette format makes the unit suitable for suspended-ceiling installations where appearance and available space are important considerations.
Efficient Fan & Motor Assembly
The fan wheel uses a one-piece injection-molded structure without welded connections between the blades and inlet components.
The design helps maintain fan balance during operation, while vibration-reducing rubber components help minimize mechanical vibration.
Each fan wheel is dynamically balanced to support stable airflow and low-noise operation.
Advanced Drainage Protection
Condensate drainage is especially important for concealed ceiling HVAC equipment.
The integrated 100 cm head drain pump assists with condensate removal, while the check valve helps prevent backflow.
A float switch provides additional protection by monitoring the water level inside the drain system. When an abnormal rise is detected, the system can activate an alarm and initiate protective measures.
This design helps improve reliability for long-term ceiling installation.
