Custom metal enclosures for cooling and power equipment

An enclosure drawing should identify its installation setting and the equipment inside. State whether it will be indoors or outdoors. Show the door openings, cable entries, vents, mounting feet and internal panels. Mark the dimensions that control the fit with the equipment. A product name such as switchgear enclosure does not define these details.

Separate the fabricated shell from the completed electrical equipment. The OEM remains responsible for the system design and its approval path. Our quote should list the metal parts, purchased hardware, assembly steps and records in scope. If the buyer supplies hinges, latches or seals, identify them by part number and state when they will be available.

NEMA enclosure types describe protection from specific environmental conditions. Type 3R includes protection against rain, sleet and external ice formation. Type 4X adds requirements that include corrosion and hose directed water. The exact enclosure design, openings, hardware and test basis matter. A thicker panel or stainless material alone does not establish the required type.

Put the required NEMA type and applicable standard on the RFQ. State whether the deliverable is an empty enclosure, a fabricated part or a completed assembly. Identify who approves the design and who supplies the test or listing evidence. Data Center Metalworks does not claim a blanket NEMA 3R or 4X rating for all custom work.

A switchgear enclosure package can include outer panels, doors, internal mounting plates and brackets. The equipment drawing must define the space around the electrical components, the door hardware and the cable access. Send the latest assembly revision so a panel change does not conflict with a control device or a bus connection.

List the finish and paint masking areas needed for the design. Show grounding points, gasket lands and the surfaces used to locate installed equipment. Mark any critical gaps or alignment features. Electrical clearances and equipment ratings come from the responsible designer. A fabrication quote should not be used as approval of the switchgear system.

Generator enclosure requirements depend on the equipment layout and the intended installation. Send the engine and generator envelope, access door locations and the details for intake and exhaust interfaces. Include the drawing for any removable roof or service panel. The builder needs to know how the equipment will be installed and later removed.

Acoustic performance, airflow, weather protection and fire requirements must be defined by the enclosure design. Do not treat a sheet metal skin as proof of any of those results. If insulation, seals or other purchased parts are in scope, include their exact references. Ask for a clear division between the fabricated enclosure and the completed equipment package.

Call out the weld process, joint details and inspection required for the design. Ask us about AWS D1.1 welder qualification when it is specified. Qualification status must be confirmed before it is used as an order requirement. Florida has robotic welding, stainless TIG and mild steel tank welding. Irving has MIG welding. Plant selection depends on the accepted scope.

Ask us about powder coat and include the required finish system. Powder coat capability and its route remain unconfirmed. Describe the color, texture, corrosion requirements, masking and permitted touch up. If tests or inspection reports are required, include their method and acceptance criteria. The quote should make the included evidence clear before a sample is built.

For an enclosure, separate the fabricated housing requirements from approval of the complete equipment. Name the environmental rating, any required listing and the party responsible for testing. Define how doors, seals and penetrations will be checked after assembly. The quote should state the evidence included for the metalwork and identify any system approval that remains with the equipment maker.

Specify the dimensional checks, finish records and material documents needed for enclosure acceptance. Mark grounding surfaces, seal interfaces and other features that need special inspection. Ask us about powder coat and AWS D1.1 welder qualification if the design requires them. Both need confirmation. A familiar enclosure shape does not establish the rating or documentation required by your project.

Use the RFQ form to send your enclosure requirement. Include the company, contact name, email, plant location, quantity and target date. Attach a PDF, DXF or STEP file up to 25 MB. A dimensioned PDF should identify the current revision and the features that control fit. Add the material grade, thickness, finish and any inspection or packing notes.

State whether you need a sample enclosure, a production lot or repeat releases. Include the required quantity and delivery address, plus the person who can approve door, seal or finish questions. Kevin Leonard handles accounts; Rich Fitzgerald handles production and sourcing. The RFQ begins the quote review. It does not reserve a production slot or approve an enclosure rating.
