Global electrical connection and protection specialist nVent Electric plc (NYSE: NVT) this month has launched its nVent HOFFMAN RackChiller CDU800 Coolant Distribution Unit (CDU), which is presented as the company’s first platform for serving the needs of high-density liquid cooling for high-performance computing (HPC), hyperscale, enterprise, as well as edge computing applications.

The company says its RackChiller CDU800 is designed to consistently deliver liquid coolant to maximize cooling efficiency while reliably removing heat from sensitive equipment through a constant pumping and heat exchange cycle.


“Content streaming, cloud computing and artificial intelligence applications are driving demand for our data center customers, who need a flexible solution they can trust and scale. Many of our customers also face space constraints. The RackChiller CDU800 delivers exceptional cooling performance while requiring the same floor space as a typical data center server rack.” -- Marc Caiola, nVent senior director for data solutions

The RackChiller CDU800 joins nVent’s extensive existing line of data center high-density liquid cooling systems.

nVent offers a comprehensive range of standard and customized air, indirect and direct water-cooling solutions to protect IT assets, whether for smaller decentralized edge computing, harsh environments, or large data center installations.

The product portfolio includes:

  • Air-to-liquid, liquid-to-air and liquid-to-liquid cooling systems.
  • Rack/row CDUs.
  • Rack and secondary fluid manifolds, as well as hose assemblies.
  • Immersion cooling components

Technical specifications

As reckoned by an nVent product introduction statement, CDU solutions providers often release theoretical performance data when launching a new product. nVent can provide RackChiller CDU800 data based on actual performance through independent lab verifications and results from early platform adopters.

Empirical data provided includes information on RackChiller CDU800’s high performance, heat exchange, flow and pressure delivery characteristics.

The RackChiller CDU800 provides 800kW of liquid cooling capacity at 4K approach temperature and delivers high-performance liquid flow, pressure delivery and heat dissipation within a standard IT rack footprint.

The new CDU is positioned as an ideal high-density liquid coolant distribution solution for close-coupled and direct-to-chip cooling applications.

nVent says the RackChiller CDU800 is designed for reliability, availability and serviceability.

The platform is designed with N+N redundant pumps that provide up to 950 liters per minute of secondary flow and 46 psi (3.2 bar) differential pressure.

The CDU includes a smart control system that monitors more than 35 integrated sensors continuously.

According to the company:

"This combination, coupled with low approach temperature throughout the operating range, can eliminate the need for costly chiller support by enabling The American Society of Heating, Refrigerating and Air-Conditioning Engineers class of W45 warm water liquid cooling of high-power IT systems."

The pumps, sensors and filtration system are serviceable without incurring downtime or impacting performance during operation.

The complete system is integrated into an aesthetical enclosure with a 10-inch color touch display, and removable side panels and doors.

The CDU can be installed onto a slab or raised floor, in a row with IT equipment racks, or a separate facility room.
