Features
Coolnet focuses on the research and development of data center cooling products, offering a full series of solutions from liquid-cooling racks, CDUs, manifolds, immersion tanks, and prefabricated piping to primary side cooling sources. The integrated design of dry coolers and supplementary cooling units—where air-cooled and liquid-cooled modules share a set of cold water trays—significantly reduces costs, saves space, and facilitates seamless on-site installation.
Coolant Distribution Units (CDU)
Highest density Coolant Distribution Units (CDU) are engineered to meet the most demanding direct liquid cooling requirements for Artificial Intelligence (AI), High-Performance Computing (HPC), and enterprise computing applications.
Coolnet’s CDUs deliver exceptional performance, density, efficiency, and reliability for data centers with or without facility water infrastructure.
Flexibility And Space-Saving
In a server cooling system, integrated CDUs enable greater processing power density, meaning more servers can fit in each data center rack. Integrate CDUs directly into facility water systems for direct rack server cooling, or design self-contained cooling that offers the next level of flexibility for liquid-cooled servers.
High Impact Cooling With Facility Water
Liquid-to-Liquid CDUs require facility water to remove heat from rack and row equipment but come with a battery of benefits to offset added system complexity. Fully liquid-cooled data centers maximize energy efficiency from the higher heat capacity of liquid throughout the entire infrastructure.
Row Type Liquid Cooling CDU
Features
- Dual pump with redundancy.
- High-efficiency stainless steel plate heat exchanger with compact structure and high corrosion resistance.
- All internal piping is made of stainless steel to ensure the system is clean and pollution-free.
- Internationally renowned brand PLC controller for secure operation.
- Intelligent PLC control program for real-time monitoring and control to ensure safe and stable operation.
- Expert-level fault diagnostics for maintenance.
- Modbus RTU, with an optional TCP/IP configuration.
- User-friendly HMI for monitoring.
- Multiple levels of passwords on the touch screen for data security protection.
Large Liquid Cooled CDU
Application Scenario
In large data centers, place the CDU in the equipment room and connect the cold plate server cabinets through pipes. The outdoor unit acts as a cooling tower or dry cooler, efficiently managing massive thermal loads.
Rack-Mounted Liquid-Cooled CDU
Features
- Dual pump redundant design allows for automatic switchover to the backup pump in case of a single pump failure.
- High-efficiency stainless steel plate heat exchanger with a compact structure and high corrosion resistance.
- Internationally renowned brand PLC controller ensures safety and reliability.
- Intelligent PLC control program for real-time monitoring and control to ensure the safe and stable operation of the unit.
- Expert-level fault diagnostics for easy maintenance and operation.
- Supports Modbus RTU, with an optional TCP/IP configuration.
- User-friendly color Human-Machine Interface (HMI) for convenient monitoring of unit operation by management personnel.
- The touch screen can be set with multiple levels of passwords to protect information security.
