TC-CDU-A300C: 300 kW In-Row Liquid-to-Air CDU
Assess the TC-CDU-A300C for Australian and New Zealand integration. The catalogue lists 300 kW, 500 L/min and a 3000 × 1200 × 2000 mm envelope; confirm the simultaneous duty and installed configuration.
Model datasheet link · no form required · confirm the document revision and quoted configuration.
Can an A300C be selected using outdoor summer temperature alone?
No. Establish the actual entering-air conditions at the unit, including recirculation and degraded room-cooling conditions. The catalogue 25/35°C air-side pair is not a guarantee at an arbitrary outdoor temperature.
Coordinate the A300C with the room cooling designer
The A300C lists a 3000 × 1200 × 2000 mm envelope, 850 kg and 500 L/min. Compared with the A120C, its larger footprint affects aisle use, service access and the path for heated discharge air.
For an AU/NZ retrofit, provide entering-air conditions for both normal and degraded room-cooling operation. The 25/35°C air-side pair is a catalogue reference, not proof of operation at an arbitrary summer ambient temperature.
Heat passes from coolant to the receiving air stream. Confirm the room or plant heat-rejection path; this equipment does not eliminate the cooling load.

Conceptual system boundary only. Connections, flow direction and controls require a project schematic.
Cabinet placement
Provide a scaled layout showing intake, discharge, doors, maintenance zones and hose routes.
Fault response
Define alarms, reduced-capacity operation and who owns the response when room cooling or liquid flow is lost.

Selection for the project location
Australia
For Australian brownfield data centres, evaluate the existing room cooling plant at the summer design condition. Do not assume liquid-to-air removes the facility heat load.
New Zealand
For NZ colocation and enterprise retrofits, coordinate the landlord or facility operator’s airflow rules and maintenance clearances before freezing a cabinet layout.
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.

Questions before ordering
Which records should accompany the TC-CDU-A300C 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.
