System role
Where it sits in the system.
Houses the IT equipment and terminates the secondary loop at the server through an integrated rack manifold.
IT loop
01 / 09 · Heat source
GPU / CPU
By others
Processor heat flux sets every downstream requirement: coolant supply temperature, flow per server and allowable pressure drop.
02 / 09 · Chip-to-liquid heat transfer
Cold plate
Interface
Coolant passes through a plate mounted on the processor. Its flow and pressure-drop figures are the design inputs for the manifold and CDU.
03 / 09 · In-rack distribution
Rack manifold
LINKWAVE scope
A stainless manifold in each rack divides supply flow between servers and collects the return through 12 mm EPDM hoses.

04 / 09 · Local coolant distribution
Rack / in-row CDU
LINKWAVE scope
Where load is distributed or facility water is unavailable, a CDU at the rack or row conditions and circulates coolant close to the IT equipment.
05 / 09 · Technology cooling system
Secondary cooling loop
LINKWAVE scope
Sanitary-grade stainless aisle piping carries treated water between the racks and the CDU. Typical supply and return: 40 / 55 °C.
View product06 / 09 · Loop isolation and control
Centralized CDU
LINKWAVE scope
A plate heat exchanger separates the IT loop from facility water. Dual variable-speed pumps hold flow and pressure. Reference units: 500 kW and 2.5 MW.

07 / 09 · Facility water system
Primary cooling loop
LINKWAVE scope
Facility water carries heat from the CDUs to the heat-rejection plant. Water quality is managed by make-up, dosing and filtration on this side.
08 / 09 · Primary circulation
Primary-side pump station
LINKWAVE scope
Skid-built pumps with variable-frequency drives, storage, make-up and dosing. 125 kW to 2.5 MW, 10–250 m³/h.
View product09 / 09 · Heat rejection
Dry cooler / cooling tower / chilled water
Interface
Three reference arrangements: isolated CDU with chilled water; isolated CDU with cooling tower and pump station; direct-connected CDU with dry cooler and online purification.
Heat travels from chip to heat rejection. Select a stage for detail.
Engineering highlights
Manifold, hoses and switchgear integrated at the factory.
- Integrated manifold
- DN50 round or ST50 square stainless manifold with 12 mm EPDM hoses to each server position.
- Top-mounted switchgear
- Power switching is located at the top of the rack, clear of the coolant connections.
