5kW Precision Split Wall-Mounted Air Conditioner

For Data Centers, Equipment Rooms & High-Ambient Shelters

CHUNSHU CS A 50 F A is a 5kW precision split wall-mounted air conditioner designed for small data centers, server rooms, equipment shelters, control rooms, UPS rooms and harsh industrial applications.

The system adopts a split structure with an indoor wall-mounted cooling unit and an outdoor condensing unit. This design helps improve installation flexibility, save indoor space and discharge heat efficiently to the outdoor environment. With a high-temperature R134a compressor, PID intelligent control and RS485 Modbus communication, the unit provides stable cooling for critical equipment rooms requiring reliable 24/7 operation.

Key Features

5kW Cooling Capacity
Rated cooling capacity reaches 5000W under L35℃/L35℃ condition, suitable for small data centers, IT rooms, equipment rooms and industrial shelters.

High-Ambient Operation
Designed to operate in harsh environments from -30℃ to +60℃, supporting reliable cooling in high-temperature applications.

R134a High-Temperature Compressor
Equipped with a Hitachi high-temperature R134a rotary compressor for stable and reliable operation under demanding ambient conditions.

Precision PID Control
The industrial-grade PID controller provides intelligent and accurate temperature control, helping maintain stable room conditions for sensitive equipment.

Split Wall-Mounted Design
The indoor unit is installed on the wall, while the outdoor unit rejects heat outside the room. This structure saves indoor floor space and improves heat rejection efficiency.

RS485 Modbus Communication
Supports Modbus + RS485 communication, auto restart and remote control, making it suitable for monitoring and system integration.

Dry Contact Alarm Output
Dry contact alarm output allows connection to site monitoring systems, helping users receive fault or alarm signals in time.

Cooling & Independent Dehumidification
Cooling and independent dehumidification functions help maintain better indoor environmental conditions for equipment rooms.

Why Use Precision Split Cooling for Equipment Rooms?

Equipment rooms are different from comfort spaces. Servers, UPS systems, batteries, switches and industrial control equipment continuously generate heat during operation. They need stable cooling even when no people are inside the room.

Compared with ordinary comfort air conditioners, CHUNSHU precision split wall-mounted air conditioner is designed for:

24/7 critical equipment cooling
high sensible heat load applications
stable temperature control
remote monitoring and alarm output
industrial-grade reliability
high ambient outdoor conditions
easy split installation and maintenance

This makes it suitable for data centers, shelter rooms, control rooms and industrial equipment rooms where cooling reliability directly affects system uptime.
