Ordering & RFQ
How to order: quote part number TC-BZP-GB200-01A with quantity and required fitting type. Custom samples are available from a single piece, each with a leak-test report; production quantities follow drawing approval.
RFQ checklist: target device and heat load, quantity, coolant type, inlet temperature, target flow rate and available envelope. Send a STEP/PDF of your tray or assembly if port position matters.
Factory Test Results
Results from a July 2026 production batch of this kit (5 sets). Full test records are available on request.
| Test | Condition | Result (limit) |
|---|---|---|
| Helium leak | 0.6 MPa, 300 s | 1.2 × 10⁻¹¹ Pa·m³/s (≤ 5 × 10⁻⁶) |
| Nitrogen hold | 0.4 MPa, 12 h | 4–6 kPa drop (< 10 kPa) |
| Cleanliness | Flush water TDS | 14.9 ppm (< 30 ppm) |
| Internal dryness | Humidity | 8.2% (≤ 10%) |
| Flatness | Feeler gauge | Pass (0.1 mm) |
Pressure Drop & Integration
Budget the cold plate pressure drop together with the quick disconnects and the rack manifold before fixing flow per tray. Use the cold plate ΔP budget guide, the QDC and manifold notes, coolant compatibility, leak-tightness testing and the design input checklist. The full list of RFQ inputs is in the cold plate RFQ checklist; when ready, request a quote.
FAQ
Can it run on warm water? The rated point is 25 °C inlet with pure water. Other inlet temperatures and coolants (pure water, EGW, PGW) are supported — performance is validated per coolant on request.
Can the ports or fittings be customised? Yes — fitting type, thread and inlet/outlet position are set per drawing without changing the qualified core.
What is included? Two GPU cold plates, one CPU cold plate, a manifold, hoses and quick disconnects, plus mounting hardware, recommended TIM and torque spec, leak-test report. Datasheet PDF available above; STEP file on request.
How is it different from the GB300 kit? This GB200 kit cools one GB200 superchip with three cold plates, two GPU and one Grace CPU, joined by one manifold; the GB300 4G+2C kit uses six cold plates for four GPUs and two CPUs. See the GB300 vs GB200 cold plate comparison before choosing.
How many kits does one GB200 NVL72 rack need? A GB200 NVL72 rack holds 36 GB200 superchips (72 GPUs and 36 Grace CPUs). One kit cools one superchip (two GPUs and one Grace CPU), so a full rack needs 36 kits (calculated: 72 ÷ 2).
