For: EveryoneHall C was built for air. The racks going into AI row 1 put out three times the heat air can move. This design takes that heat off the chips with liquid and hands it to the facility water loop you already have.
Cold plates sit on the CPUs and GPUs. About 85% of the heat leaves in the coolant. A rear door catches the rest before it reaches the room.
Your facility water stays on one side of the CDU. Clean, filtered coolant runs to the servers on the other. A plate heat exchanger moves heat between them.
Dry-break couplings at every tray. Valves at every rack. Filters and pumps change from the front without stopping the row.
Built for everyone who signs off
Warm water, sized flows, one tap per row. Sections 06 and 07.
15 kW per CDU at most, dual feeds, N+1 pumps. Section 08.
Pull a server without draining. Map to your cold plates. Section 09.
Every point in your BMS. One leak, one rack. Section 12.
Per-rack kits, five-year warranty, one vendor to call. Section 11.
Liquid to the chip, heat out of the building, and nothing on the floor.
Arvane Thermal designs the Tidepath line of coolant distribution units, rack manifolds, rear doors and leak protection. We build it for halls that were designed for air and now have to carry AI loads.
We do not hand you a parts list. We draw your rows, size every pipe, pressure-test every manifold and hose before it ships, label it to the drawing, and stand next to your team when the loop fills for the first time.
How we run your project
We draw your rows and racks, size every flow, and agree them with your engineers.
A pilot rack runs at full load on a load bank. You test it against a pass list you approve.
We build, pressure-test, cap and label each rack kit. One crate per rack.
We fill, flush and load-test with your team, then stay on the account. Same person, same number.
The CDU feeds every rack in the row through overhead headers. The colors here are used in every diagram in this kit.
| Role | Product | Part number | Key point | Power |
|---|---|---|---|---|
| Cooling, row | In-row coolant distribution unit | TP-C1200 | 1.2 MW. N+1 pumps. Facility water and server coolant never mix. | 2x 400-480 VAC, 3-phase |
| Cooling, rack | In-rack CDU, 4U | TP-C120 | 120 kW. For a pilot rack or a single high-density rack. | 2x 208-415 VAC |
| Distribution | Rear rack manifold, 0U | TP-M48 | 24 supply and 24 return ports. Flow and temp sensing built in. | None |
| Distribution | Dry-break quick disconnect | TP-Q12 | Push to connect. No drip on release. One pair per tray. | None |
| Distribution | Isolation valve set | TP-V | Motorized. Shuts one rack off the header in seconds. | 24 VDC from TP-LX |
| Air side | Rear-door heat exchanger | TP-RD50 | 50 kW. Catches the heat the cold plates miss. | 208-240 VAC, fans |
| Safety | Leak controller and rope | TP-LX / TP-LR | Finds a leak to within 1 m and closes that rack's valves. | 100-240 VAC |
| Monitoring | Monitoring software | TP-View | Every flow, pressure, temp and leak point. Talks to your BMS. | Your VM or ours |
Pick the CDU by how many racks it feeds. Add a rear door wherever air heat is left over.
Sits at the end of the row like a rack. Moves heat from your server coolant into facility water.
One rack on its own: a pilot, a lab, or a single dense rack in an air-cooled hall.
Hangs on the back of the rack. Takes the 15% of heat that still goes to air.
Distribution and protection
Mounts in the rear 0U space. Feeds every tray in the rack from one supply and one return.
The coupling at every tray. Pull a server without draining anything.
Rope runs under every rack and CDU. The controller finds the leak and acts on it.
Monitoring and service
Every CDU, manifold, door and leak point on one screen, with the same names in your BMS.
Fills, bleeds and tops up a loop. Comes with the pilot and every row kit.
Propylene glycol, 25%, with corrosion inhibitor. Pre-mixed, so nothing is mixed on site.
Three designs, each a step up from the last. All three use the same parts, so nothing you buy for the pilot is wasted.
One rack with its own in-rack CDU. Proves the cooling, the leak response and the BMS link before the row goes in.
One in-row CDU feeds eight 120 kW racks through overhead headers. Every rack has its own valves, rear door and leak coverage.
Each row gets two CDUs for N+1. A facility water ring main joins them all to your plant.
A sample layout for AI row 1 and one of its racks. Final positions are yours; we redraw this after the site walk.
Pipes stay out of the cold aisle, where people work and servers breathe. Any drip lands where the rope is.
One row on one unit keeps fault domains small. Add a row, add a CDU. Nothing upstream changes.
Cold plates miss memory, drives and power supplies. The door takes that heat, so your existing CRAHs are not asked to do more.
Your facility water and our server coolant meet only inside the CDU. Here is who owns what, and how each part is built.
Every pipe, hose and connection, by name
| Part | Where it goes | Guidance |
|---|---|---|
| Facility water (FW) mains | Your plant to the CDU | Your pipe and your spec. DN100 grooved at the CDU. We give you flow and temps. |
| TCS headers | CDU to the row, overhead in the hot aisle | 316 stainless, DN80. Pressure-tested before it ships. Supply blue, return red. |
| Rack drops | Header to the TP-V valves on each rack | 1.5" braided hose, cut to your drawings. Pressure-tested and capped. |
| Tray hoses | Manifold port to server | EPDM, 1/2", TP-Q12 on both ends. Length per tray position. |
| Isolation valves | Top of every rack drop | TP-V motorized pair. Manual override on the handle. |
| Bleed and drain | Top and bottom of every manifold | Bleed at the top, drain at the bottom, both capped in normal use. |
| Leak rope | Under every rack and the CDU | TP-LR, on clips, never under a pipe joint you cannot reach. |
| CDU power | Busway A and B to the CDU | 2x 400-480 VAC, 3-phase. Internal transfer between feeds. |
| Monitoring network | CDU, TP-LX and doors to TP-View | Your management VLAN. RJ45, or RS-485 for Modbus RTU. |
The full two-page sheet your engineers will ask for. Every Tidepath datasheet follows the same order, so nothing takes hunting for.

Seven steps for your installer. One action per line, lettered callouts that match the drawing, and the pressure warning where it belongs.
Mount, fill, test, flow
This guide is for an experienced mechanical installer. It covers mounting the TP-M48 rear rack manifold, connecting it to the row header through TP-V valves, filling, pressure testing and first flow to the trays.

BReturn ports, red, 24
CTP-V isolation valves, top inlet

G0U mounting brackets
Confirm both TP-V valves C are closed and locked out in TP-View before you touch the drop.
| Point | Normal at full load |
|---|---|
| FInlet temp | 38 °C, ±0.5 K |
| FRack ΔT | 8 to 10 K |
| Flow per tray | 8 to 10 L/min |
| Leak status | Dry, green in TP-View |
Anything outside these ranges raises a warning in TP-View and in your BMS.

We draft this list. You edit it. The pilot passes when your team checks every line.
We build, pressure-test and label each rack kit, then ship it to your integrator ready to install.
The questions we hear in every design review. If yours is not here, it goes on the list for the site walk.
No. The CDU runs on 32 °C facility water. That is warm enough for dry coolers to carry it most of the year, so your chillers only trim.
Facility water at up to 35 °C, about 1,500 L/min per CDU at full load, and a DN100 tap. We give you the flow and pressure drop in writing.
The CDU alarms at once and TP-View tells your BMS. Servers throttle on their own limits. We size ride-through time with you during design.
Up to 15 kW at full flow, usually far less. Two feeds, A and B, with transfer inside the unit.
Nothing you can feel. Pumps are N+1. The standby takes over, TP-View raises a warning, and the failed pump swaps out from the front.
Yes. Every tray sits on TP-Q12 dry-break couplings. Release, slide out, done. The rest of the rack keeps flowing.
The rope finds it to within 1 m. TP-LX closes that rack's valves and alerts your BMS. One rack goes quiet, the row keeps running.
We map couplings and hose lengths to your server specs before the quote. If the vendor ships its own couplings, we match them.
Every flow, pressure, temp and leak point, by rack, in your BMS and DCIM. Same names in TP-View and in your systems.
A coolant sample every quarter, which we test. Filter changes when TP-View says so. Both happen with the loop running.
