TLS Energy provides DSX POD enclosures with an integrated delivery approach: supply the enclosure, install the racks, connect the internal systems, flush and pressure-test the cooling loop, then power on and test the assembled unit before shipment. This sequence brings assembly and verification into the factory, helping customers receive a coordinated package with clearly defined interfaces. For projects involving liquid cooling and interconnected racks, the value lies in checking how the components work together before the enclosure reaches its destination.
A DSX POD enclosure provides the physical structure around the equipment and its supporting infrastructure. The enclosure design must account for equipment placement, service access, cable routing and cooling connections. These requirements influence each other. Rack positions affect pipe routes, while access requirements influence the location of doors and internal clearances. Addressing these relationships during enclosure integration helps avoid installation conflicts later. TLS Energy’s delivery scope should therefore be defined around the complete assembly and the customer’s agreed project requirements.
Rack installation establishes the internal arrangement of the DSX POD enclosure. Racks need suitable mounting positions and secure attachment, with sufficient space for connections and maintenance. The layout should also accommodate the equipment that will occupy each rack. Dimensions, loading requirements and access arrangements must be confirmed against the project design. Installing racks at the factory allows the enclosure and rack arrangement to be checked together, giving the integration team an opportunity to resolve physical mismatches before dispatch.
Connecting the racks turns the enclosure into an integrated assembly. Depending on the agreed scope, this work can include electrical distribution, grounding, communications, control wiring and cooling connections. Each connection should follow approved drawings and component requirements. Clear identification of cables, pipes and connection points supports inspection and later maintenance. NVIDIA describes factory integration as a central feature of the DSX POD approach, moving cabling, wiring, piping and functional validation into the manufacturing stage. NVIDIA DSX POD overview
The cooling loop requires particular attention because installation quality affects fluid circulation and equipment cooling. Pipework, manifolds, valves and rack connections must form a circuit that matches the approved design. Connections also need to remain accessible for inspection and service. Before commissioning begins, the integration team should confirm component compatibility and the boundaries of the supplied cooling system. Establishing those boundaries clarifies which cooling functions belong inside the enclosure and which depend on infrastructure provided at the installation site.
Flushing the cooling loop prepares the assembled circuit for operation. Fabrication and installation can leave particles or other contamination inside pipework. A controlled flushing procedure helps remove this material before normal circulation begins. The procedure should follow the requirements of the installed components and the specified coolant system. Cleanliness acceptance criteria, flushing arrangements and fluid handling need to be agreed for the project. Completing this work at the factory gives the team access to the assembled loop while corrective work remains practical.
Pressure testing checks the cooling loop’s integrity before the unit is switched on. The test procedure must specify a suitable medium, pressure, duration and acceptance criteria based on the system design and component limits. Inspection focuses on joints, fittings and other potential leakage points. Any defect identified during testing requires correction and appropriate verification before the assembly proceeds. Flushing and pressure testing serve different purposes: flushing addresses internal cleanliness, while pressure testing checks whether the circuit meets its specified integrity requirements.
After the cooling loop passes the required checks, the assembled unit can proceed to controlled startup and functional testing. Switching on provides an opportunity to verify the operation of the equipment included in TLS Energy’s contracted scope. The test plan should define the required checks, operating conditions and acceptance criteria. Where applicable, these checks may cover controls, sensors, alarms and cooling circulation. The extent of operational testing depends on the installed equipment and the utilities available at the factory test location.
Factory testing provides useful evidence for shipment acceptance and subsequent commissioning. Test records should identify the inspected assembly, describe the procedures performed and document results against agreed criteria. Outstanding items need clear ownership and resolution requirements. Customers should distinguish between testing the enclosure’s integrated infrastructure and validating a complete computing workload. The purchase specification should state which equipment is installed, which functions are demonstrated and which activities remain for site commissioning. This clarity helps align delivery expectations with the actual supplied package.
For customers considering TLS Energy DSX POD enclosures, procurement discussions should begin with the required delivery boundary. Confirm the enclosure configuration, rack arrangement, internal connections, cooling loop scope and factory acceptance requirements before manufacturing starts. Site teams can then prepare the external services and receiving arrangements around those interfaces. An enclosure that has been assembled, connected, flushed, pressure-tested and powered on under an agreed test plan gives the receiving team a documented starting point for installation and commissioning at the destination.
