CDU0402R001

The nVent HOFFMAN RackChiller CDU40 (SKU: CDU0402R001) is a high-performance, rack-based Coolant Distribution Unit engineered to meet the stringent thermal management demands of modern High-Performance Computing (HPC) environments. This unit is designed to efficiently dissipate up to 40kW of heat load, fitting compactly within a standard 4U rack space, making it ideal for dense computing deployments where space is at a premium. Leveraging advanced heat exchange technology, the RackChiller CDU40 utilizes ASHRAE W4 warm water to effectively manage the significant heat generated by processors and other critical components. This approach offers a highly efficient and reliable method for maintaining optimal operating temperatures, thereby enhancing system stability and longevity. The unit features a robust, non-ferrous liquid circuit constructed with a stainless steel centrifugal electric pump, a durable plastic storage tank equipped with a drain valve, and an electrical level indicator. For operational monitoring and protection, it includes a bar pressure gauge and a differential pressure switch to safeguard water flow. An automatic by-pass and regulation sensor further ensure precise temperature control. The electrical panel is equipped with a main disconnect switch, relay motor protection, and phase sequence relays for comprehensive power management and safety. The integrated TX350C control unit provides sophisticated management of the chiller's operation, offering detailed operator alarm diagnostics and enabling remote on-off switching via a dedicated contact. An illuminated control selector and an RS485 connection facilitate easy operation and integration with broader building management systems, with the possibility of a remote display for enhanced machine regulation. Key features and benefits include: * **High Heat Dissipation:** Capable of managing 40kW+ heat loads. * **Compact 4U Design:** Maximizes rack space efficiency. * **Efficient Warm Water Cooling:** Utilizes ASHRAE W4 warm water for effective thermal management. * **Robust Liquid Circuit:** Stainless steel pump, plastic tank with drain valve, pressure gauge, and flow protection. * **Advanced Control System:** TX350C unit with diagnostics and remote control capabilities. * **Durable Construction:** Brazed stainless-steel plate evaporator and microchannel condensing coil. * **Safety Features:** Thermal cut-out on axial fan, safety grilles, and phase sequence relays. Optional configurations are available to tailor the unit to specific environmental and application needs, including flow switches (FL), fluid heating elements (HR), outdoor operation capabilities down to -10°C (OM) or -20°C (OML), air filters (FP), differential fluid temperature management (TD), and hot gas bypass for precise temperature control (+/– 1 K) (BGC). A specialized liquid circuit for laser applications with a high-pressure pump version (LS - "H" 5 bar) is also an option. Manufactured in the USA, the nVent HOFFMAN RackChiller CDU40 is built to the highest standards of quality and reliability, making it a trusted solution for critical infrastructure cooling in data centers, research facilities, and other demanding industrial applications.
