Product Description
The 5KW vertical plug-in industrial liquid cooler for battery cabinet is an integrated cooling solution developed for battery energy storage systems and containerized battery equipment.
This liquid cooling unit combines a refrigeration system and coolant circulation system in a compact modular design that can be embedded into equipment frames. By circulating a 50% ethylene glycol coolant, the system efficiently removes heat generated by batteries and maintains a stable operating temperature inside battery cabinets.
Equipped with intelligent temperature control, automatic restart after power failure, and RS485 communication capability, the cooler supports reliable remote monitoring and system integration. With a cooling capacity of 5KW and circulating flow up to 50L/min, it provides stable and energy-efficient cooling performance for modern battery storage applications.
1.Intelligent Temperature Control
Automatically adjusts cooling and heating to maintain stable battery temperature.
2.Vertical Plug-in Design
Compact structure allows easy integration into battery cabinets or equipment frames.
3.RS485 Communication Support
Enables connection with monitoring systems for remote control and diagnostics.
4.Auto Restart After Power Failure
Operating parameters are saved and the unit restarts automatically after power recovery.
5.Stable Liquid Cooling Circulation
High-flow coolant circulation improves heat transfer and battery cooling stability.
