Product Description

Coolant Distribution Unit
Introduction
The Coolant Distribution Unit (CDU) is the core component of the water cooling system, responsible for efficiently distributing the coolant to meet various cooling needs. By integrating auxiliary monitoring and support devices, the CDU ensures stable operation of the system.

It is mainly used for heat exchange control in liquid cooling systems, incorporating secondary side variable frequency circulating pumps, plate heat exchangers, electric control valves, temperature sensors, pressure sensors, filters, expansion tanks, flow meters, and online replenishment functions.

Key Features

📱10-inch Touch Screen: Multi-level authority control, easy to operate.
🧩Modular Design: Flexible expansion according to demand.
High-Efficiency Pump: Variable frequency pumps automatically adjust flow rate.
🛡️Corrosion-Resistant: Made with 304 stainless steel for long service life.
📊Intelligent Control: Includes anti-condensation and conductivity monitoring.
🔇Ultra-Quiet Motor: Low noise suitable for quiet environments.
📡Smart Protocol: Supports Modbus TCP with comprehensive alarm functions.
💧Precision Filtration: Wide design range of 25~100μm.

Our Advantages

The CDU optimizes the performance and reliability of the water cooling system. It features six channels that connect the main circuit to the secondary water distributor, reducing installation errors. Incorporating a multi-stage centrifugal pump ensures efficient flow, while an integrated expansion tank maintains stable pressure levels. To prevent corrosion and cavitation, an automatic air vent valve eliminates non-condensable gases from the system promptly.

Frequently Asked Questions

1. What is the primary function of a Coolant Distribution Unit (CDU)?
The CDU is the central component of a liquid cooling system, responsible for managing heat exchange and efficiently distributing coolant to the equipment that needs cooling.
2. Which mediums are compatible with this CDU system?
The primary side supports softened water and ethylene glycol solutions, while the secondary side is compatible with deionized water, ethylene glycol, and propylene glycol solutions.
3. How does the system handle pressure fluctuations?
The CDU includes an integrated expansion tank that compensates for temperature-induced volume changes, maintaining stable pressure levels throughout the system.
4. What kind of monitoring and control does the interface provide?
The unit features a 10-inch touch screen with multi-level authority control, supporting Modbus TCP for remote monitoring of temperature, flow, and conductivity.
5. How is the durability of the unit ensured?
The unit is constructed using 304 stainless steel and higher-grade materials to ensure excellent corrosion resistance and a long operational lifespan.
6. Does the CDU require complex on-site installation?
No, the CDU is pre-installed and debugged at the factory, which significantly reduces the time and effort required for on-site commissioning.
