TC-CDU-L50R: 50 kW In-Rack Liquid-to-Liquid CDU
Assess the TC-CDU-L50R for Australian and New Zealand integration. The catalogue lists 50 kW, 160 L/min and a 482 × 870 × 177.8 mm envelope; confirm the simultaneous duty and installed configuration.
Model datasheet link · no form required · confirm the document revision and quoted configuration.
Why does the L50R list the same flow as the L100R?
Both catalogue entries list 160 L/min, but L50R lists a 50 kW capacity reference and a 40/45°C technology-loop temperature pair. A shared flow value does not establish equivalent duty; request a configuration-specific selection.
Do not infer duty from the shared L50R and L100R flow value
The L50R lists 160 L/min, matching the L100R flow reference, but has a 50 kW capacity reference and a 40/45°C technology-loop temperature pair. These values must be tied to a specific accepted operating point.
For a pilot rack, request part-load performance and the temperature-control method when only a few branches operate. Confirm the fluid properties and useful external pressure before assigning a pump margin.
The technology loop transfers heat through a heat exchanger to facility water. Confirm both circuits; this CDU is not an independent refrigeration source.

Conceptual system boundary only. Connections, flow direction and controls require a project schematic.
Rack fit
Check rack format, available height, mounting points and connections. A rack-height label alone does not establish fit.
Flow under a fault
Request the usable pump curve and operating point with the agreed redundancy state. Pump count alone does not prove full-duty redundancy.
Catalogue references for TC-CDU-L50R

Confirm coolant properties, inlet/outlet conventions, pressure available to the load, mass basis and offered electrical configuration in the accepted selection.

Selection for the project location
Australia
For Australian AI and HPC racks, review facility-water availability during peak plant load and the technology-loop pressure budget, including hoses and quick disconnects.
New Zealand
For NZ integrators, request a rack drawing and confirmation of the facility-water boundary from the host site. Include the agreed commissioning and spares responsibilities.
Electrical configuration is a release item. Catalogue voltage and frequency options do not establish compatibility with the site supply. Confirm voltage range, phase, frequency, earthing, protection and the applicable product documentation before order.

Supply and project responsibilities
Australian customer communication
ToneCooling Australia Pty Ltd coordinates enquiries for Australian and New Zealand customers. Manufacturing is in Huizhou, Guangdong, China.
Quoted supply boundary
Confirm equipment, fittings, coolant, documentation, freight destination and commissioning responsibility. Local stock and on-site service are not implied.
Configuration-specific evidence
Request the relevant drawings and inspection records. Site approvals, installation and system-level compliance remain separate from a component catalogue description.
Prepare your enquiry
Send the conditions that determine the design.

Questions before ordering
Which records should accompany the TC-CDU-L50R quotation?
Ask for the selected duty point, pump curve with pressure available to the load, general arrangement, offered electrical configuration, controls point list and acceptance-test scope. Identify document revisions in the quotation.
Are the catalogue power, flow and temperature values a guaranteed single operating point?
No. Request a configuration-specific selection using your coolant, air or facility-water conditions and required external pressure. The listed references are not a substitute for an accepted performance curve or test.
Is this equipment stocked or installed locally?
Stock, installation, commissioning and response times must be confirmed in the quotation. This page does not promise local inventory or an on-site service network.
Can I select from the catalogue rating alone?
No. Confirm the operating conditions, mechanical and electrical interfaces, fluid properties and acceptance test. Catalogue references must match the quoted configuration.
Can the same enquiry cover a New Zealand project?
Yes. Include the New Zealand delivery location, site conditions and required documentation so that supply and service responsibilities can be agreed.
