Chilled Water Ceiling Cassette Fan Coil Unit HVAC System 2 Pipe 4 Way

The 2 Pipe 4 Way Cassette Fan Coil Unit is a ceiling-mounted water-based HVAC terminal designed for efficient cooling and heating in residential and commercial spaces. Its compact cassette structure delivers balanced four-direction airflow while saving valuable floor and wall space.

With a high-efficiency copper-aluminum coil, low-vibration fan motor, intelligent drainage protection, and flexible control options, the unit provides reliable indoor comfort for hotels, offices, apartments, retail spaces, and other modern buildings.

1. Four-Way Air Distribution
   Delivers uniform airflow in four directions for more consistent indoor comfort.
2. Compact Ceiling Installation
   Designed for concealed ceiling applications where space efficiency and clean aesthetics are important.
3. High-Efficiency Heat Exchange
   Copper tubes combined with aluminum fins provide effective heat transfer for stable HVAC performance.
4. Low-Noise Fan Assembly
   Precision-balanced fan wheels and vibration-reducing components help minimize operating noise and vibration.
5. Reliable Drainage Protection
   Integrated drain pump and float switch help reduce the risk of condensate overflow and water leakage.
6. Flexible Control Options
   Supports remote control, wired control, RS485 master-slave communication, and optional WiFi connectivity.
7. Optional Fresh Air Connection
   Fresh air intake can be configured according to project ventilation requirements.

The cassette-style indoor unit is designed to fit neatly into suspended ceilings while maintaining effective air circulation.

The four-way outlet structure distributes conditioned air across the room, helping reduce temperature differences between different areas. The galvanized steel body and insulated internal air passages provide a durable enclosure with improved thermal and acoustic performance.

The ABS decorative panel features a washable air filter and automatic swing function, combining practical maintenance with a clean appearance.

The heat exchange coil uses copper tubes and high-surface-area aluminum fins to improve heat transfer between the circulating water and indoor air.

Each coil is pressure-tested to help ensure reliable operation and reduce the risk of leakage during system service.

Coil Configuration:

1. Copper heat exchange tubes
2. Aluminum fins
3. Large heat exchange surface
4. Pressure-tested construction
5. Suitable for chilled and hot water HVAC systems

The fan assembly is designed for smooth and stable operation.

The fan wheel is manufactured through precision injection molding without welded blade connections, helping maintain consistent balance. Anti-vibration components are incorporated around the motor and fan assembly to reduce mechanical vibration and operating noise.

This makes the unit suitable for comfort-focused applications such as bedrooms, offices, hotels, apartments, and commercial interiors.

Condensate management is an important part of a ceiling-mounted fan coil system.

The unit incorporates a high-head drain pump with a check valve together with a float switch. When the condensate level rises abnormally, the float switch can trigger an alarm and initiate protective control to help prevent water overflow.

This drainage design provides an additional layer of protection for ceiling installations.

The indoor unit combines galvanized steel, insulated air passages, ABS components, copper tubing, and aluminum fins to create a robust structure for long-term HVAC operation.

The internal insulation helps reduce heat loss and condensation while also contributing to quieter operation.
