Product Feature

High Efficiency and Energy Saving

The design features large air volume, small enthalpy difference, and a high sensible heat ratio. High-efficiency compressors, EC fans, and electronic expansion valves are used. The outdoor fan adopts stepless speed regulation, and the group control function optimizes overall energy consumption. R410A refrigerant is used as standard for environmental and energy efficiency benefits.

Stable and Reliable Operation

The unit uses well-known brand core components and a mature system architecture. Multi-level alarm and protection functions include power failure protection, water leakage protection, temperature and humidity over-limit protection, and phase sequence detection. It supports ultra-wide voltage operation and intelligent auto-restart after power recovery for continuous site operation.

Intelligent Monitoring and Group Control

A color touch screen provides real-time component status display. Multi-level password protection classifies alarm events by severity. Master-standby rotation and backup group control are supported. The built-in RS485 Modbus interface enables remote parameter setting, status reading, and alarm notification.

Flexible On-Site Deployment

Standard threaded quick connectors allow fast installation without complex welding. Multiple air supply modes are selectable to match room layout. Optional auxiliary electric heating and electrode humidification modules meet diverse local temperature and humidity control requirements.
