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 an EC fan dry cooler for natural free cooling with a mechanical cooling module. In favorable ambient conditions, chillers can be shut down entirely for ultra-low energy operation.
Uses air as the primary cooling medium, eliminating cooling tower water consumption and the associated chemical treatment and maintenance overhead.
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 across seasons.
Designed for continuous outdoor 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 protocol support. Compatible with BMS and third-party monitoring platforms for centralized facility management.
