Coolant Distribution Unit Components
1. Pump Chambers
The pump chambers regulate fluid flow through the CDU. Its proprietary three-chamber design pulls fluid through the loop while keeping the flow steady.
2. Heat Exchangers
The CDU’s two series-connected heat exchangers transfer up to 300 kW of heat from the technology cooling system to the facility water system, even in hot, humid conditions.
3. Liquid Ring Pump
Liquid ring pumps use water as a seal that never needs to be replaced. The CDU’s liquid ring pump provides the vacuum used to pull the coolant through the load.
4. Microprocessor Control
The CDU’s intelligent, network-connected core automatically manages coolant temperature, flow, water quality, and more. Cool-Flo Software integrates easily with popular DCIM and BMS systems.
5. Water Quality Control
The CDU automatically monitors and maintains water quality in the technology cooling system, dispensing coolant additives as needed to prevent corrosion and biological growth.
6. Coolant Handling Manifolds
The CDU supports up to four cooling loops with flexible top or bottom connections, compatible with both raised-floor and overhead piping for easy installation in different data centers.

Yes. Flow rate, pump head, connection size, voltage, coolant ratio, communication and control logic can be engineered around site conditions and equipment requirements.
Yes. Factory-installed, pre-piped and pre-wired options can include manifolds, leak detection and container-level controls. Final integration depends on the container layout and transport requirements.
Water and water/ethylene-glycol mixtures are common project options. The final fluid and concentration depend on climate, freeze protection, material compatibility and equipment requirements.
N+1 dual-pump configurations support automatic switchover and can maintain circulation during some scheduled pump-service tasks. The exact maintenance boundary depends on isolation valves and the final system design.
Yes. PLC controls, alarm monitoring and Modbus communication can connect the CDU to DCIM, BMS or project-specific remote supervision platforms.
A complete project typically requires 14-22 weeks after technical confirmation. The schedule depends on capacity, customization, FAT scope, documentation, shipping and site-service requirements.
