CDU-side boundary
- Built around customer-defined CDU inlet and outlet ports
- CDU unit manufacture and controls stay outside Chelsey scope
CDU Connection Modules
CDU Connection Modules
Integrated piping assemblies and valve trains built around specified CDU interfaces.
Drawing-based build
Protected delivery
Where it fits
CDU-side piping around defined equipment interfaces.
These modules sit around customer-defined CDU inlet/outlet ports and adjacent pipework. They cover fabricated connection hardware, not CDU unit manufacture or CDU controls.
[02]
Interface hardware
- Valve, QD, hose, adapter, and gauge positions come from the package
- Mounting envelope and service access should be confirmed
[03]
Module handoff
- Labels, cleaning, test support, and packing align to the approved BOM
- Final system acceptance remains customer-owned
Product family overview
CDU connection packages built around defined interfaces.
01 / Customer drawing
Interface envelope
CDU inlet / outlet location, adapter length, valve access, and service clearance follow the customer drawing.
02 / Approved BOM
Connection standard
Clamp, flange, hose, thread, sanitary clamp, QD, or adapter standard follows the approved BOM.
03 / When specified
Component integration
Ball valves, clamps, gaskets, QDs, gauges, drains, vents, and brackets are installed when specified.
04 / Medium defined
Seal compatibility
Gasket and seal materials are matched to DI water, EG, PG, or other project-defined media.
05 / Fit check
Assembly orientation
Valve handle direction, label position, flow direction, and obstruction checks are reviewed before build.
06 / Project requirement
Testing & delivery
Leak / pressure test, cleaning, capping, labeling, and protected packing follow project requirements.
Scope boundary
Customer defines the system. Chelsey fabricates the hardware.
This section keeps the manufacturing scope, interface inputs, and handoff boundary visible without turning the family page into a system-design page.
Drawing package
Starts from customer drawings, BOMs, samples, or interface requirements.
Interface discipline
Connection standard, material, seals, and component preferences should be confirmed before fabrication.
Fabrication support
Stainless fabrication, component integration, cleaning, capping, and labeling stay inside the approved scope.
Quality boundary
Test support per customer protocol, packing, and export-ready delivery can be aligned.
Buyer handoff FAQ
Frequently asked questions
01What should be prepared before a product-family review?
Send drawings, BOMs, samples, interface requirements, pressure requirements, component preferences, quantity, and packing destination.
02Does Chelsey define the full cooling system?
No. Chelsey fabricates and integrates hardware within the customer or integrator design package.
03Can customer-specified components be used?
Yes, when the selected valves, quick disconnects, hoses, fittings, or sensors are available and compatible with the approved scope.
04Can testing be included?
Test support per customer protocol, leak review, cleaning, visual inspection, and packing checks can be aligned before delivery.
