Data Center Infrastructure Manufacturing
Power, Cooling, and Controls
Lotus provides data center infrastructure manufacturing for OEMs that build power distribution, liquid cooling, and monitoring equipment. We assemble control boxes, enclosures, harnesses, and sensor components to your specifications, with testing, inventory storage, and depot repair in Canton, Michigan.
Additional Capacity for Your Equipment Program
Whether you are qualifying another supplier or adding capacity for an existing product, we start with the assembly, the expected volumes, and the requirements your production partner needs to meet.
Qualifying a Second Source
Share your drawings, bill of materials, approved vendor list, and supplier quality requirements. We review the work and plan first articles and pre-production builds with your team.
Planning Assembly Capacity
Dedicated cells and buffer inventory can be included in a program. We review expected volumes, component availability, and release schedules before agreeing the production plan.
Matching the Assembly Environment
Sensor and monitoring assemblies may have specific contamination-control requirements. We review those requirements to determine which steps need cleanroom space and which can run on the main assembly floor.
Control Boxes, Harnesses,
and Sensor Assemblies
Our data center infrastructure manufacturing work supports the equipment OEMs supplying power, cooling, and monitoring systems. The scope includes control-board box build, enclosure integration, wiring, sensor assembly, and functional testing to your procedures.
At our 300,000 sq. ft. Canton facility, assembly, inventory storage, and depot repair operate at the same site. Sensitive component work can use our ISO Class 6 and Class 7 cleanroom space when your process requires it.
Lotus holds ISO 9001:2015 and ISO 14001:2015 certification. We review your qualification, inspection, and documentation requirements before a program begins.
- Power equipment: control-board box build and enclosures for busway tap boxes, PDUs, static transfer switches, UPS monitoring, and switchgear controls
- Cooling equipment: CDU controller boxes, pump and valve controls, and manifold or quick-disconnect sub-assemblies
- Monitoring: leak-detection harnesses, flow and temperature sensors, DCIM nodes, and EPMS or BMS gateways
- Matched cable and harness kits
- Dedicated capacity, consigned inventory, and depot repair available
From Supplier Review to Production and Repair
We agree the assembly scope, qualification steps, testing, and delivery requirements with your team. Inventory and depot services can be included where needed.
-
Supplier Qualification & NPI
Review your supplier quality manual, drawings, and acceptance criteria. Complete the agreed onboarding, first-article, and pre-production steps before volume production.
-
Control-Board Box Build & Integration
Integrate supplied control boards, enclosures, wiring, and connectors to your documentation and approved vendor list, with lot traceability.
-
Sensor, Harness & Leak-Detection Assembly
Assemble sensors, leak-detection harnesses, and matched cable kits. Use ISO Class 6 or Class 7 cleanroom space where specified by the process.
-
Test & Documentation
Functional and electrical tests to your procedures, including dielectric or hi-pot testing where required. Provide the agreed per-unit test and traceability records for your product documentation.
-
Consigned Inventory & Staged Release
Hold agreed buffer stock and consigned components in our on-site warehouse. Kit and release inventory against your build schedule, with 12 truck wells for receiving and dispatch.
-
Depot Repair for Field Returns
Returned controllers and monitoring or cooling electronics come to our depot for diagnosis, component-level repair, and testing. Repair findings are shared with your engineering team.
Visit the Team in Canton, Michigan
Your engineering and quality teams can visit our Canton facility to review the assembly process, inspect samples, and discuss production requirements. The review can include cleanroom operations, inventory arrangements, and repair support.
With warehousing and depot repair at the same site, we can plan component intake, production releases, and field returns together.

We assemble components for OEMs that supply power distribution, liquid cooling, and monitoring equipment. Work includes control-board box build, enclosures, wiring, sensor assemblies, leak-detection harnesses, and matched cable kits. We work to the equipment OEM's drawings and test requirements.
No. This service focuses on control, sensing, and power-distribution assemblies for infrastructure equipment OEMs. Server, GPU, and rack integration are outside this page's assembly scope.
Yes. We review your drawings, bill of materials, approved vendor list, supplier quality manual, and test procedures. We then agree the first-article and pre-production work needed for qualification, along with capacity and inventory arrangements.
We don't fabricate bare boards. SMT and through-hole assembly is available through our strategic partner, built to IPC Class 3, and we integrate those boards, or yours, into the control-board box build along with enclosure, harness, and sensor assembly.
No. The OEM retains responsibility for its product listings. Lotus follows the controlled design and production documents and provides the agreed inspection, test, and traceability records. We review those requirements with your team before production.
Yes. Our facility has 20,000+ sq. ft. of ISO Class 6 and Class 7 cleanroom space. Sensitive assembly steps can run there when the specification calls for it; standard box build and harness work can use the main assembly floor.
Yes, through our Energy Storage & Batteries offering. That scope includes BMS controller box build, pre-welded module integration, enclosure assembly, testing, and battery returns support. We review battery work separately from the power, cooling, and monitoring assemblies described here.
Yes, within an agreed depot scope. Controllers, monitoring modules, and cooling electronics can return to Canton for diagnosis, component-level repair, and testing, with repair findings shared with your engineering team.
Send the drawings, bill of materials, expected quantities, target dates, and test procedures. Include the supplier qualification requirements and identify any cleanroom, consigned inventory, or repair support you need. These details help us assess the build and plan the next steps.
