Indoor dual-cooling-source heat rejection module combining natural free cooling and mechanical cooling in a single unit. Maximizes free cooling hours to reduce chiller dependency and energy consumption.
Combines natural free cooling and mechanical cooling in one integrated unit. In favorable ambient conditions, chillers can be shut down entirely — achieving ultra-low energy consumption.
Uses air as the cooling medium instead of water, eliminating cooling tower water consumption and the associated chemical treatment requirements.
Supports cold standby, hot standby, single-machine, group control, and local/remote operation. Multiple units automatically form a network for coordinated management.
Wide range of cooling capacity and temperature regulation. The air-to-liquid ratio adjusts dynamically based on ambient conditions to maintain optimal efficiency.
Designed for continuous operation — 24 hours a day, 365 days a year — with a service life of no less than 10 years.
RS485 and RJ45 interfaces with Modbus RTU and Modbus TCP support. Compatible with BMS and third-party monitoring platforms.
