Data Center Infrastructure Assembly.
Power, Cooling, and Controls.
Contract manufacturing for the OEMs that supply data center power distribution, liquid cooling, and monitoring equipment — control-board box build, enclosure integration, sensor and leak-detection harness assembly, test, consigned inventory, and depot repair for field returns. Dedicated line capacity and cleanroom for high-reliability sensor work. ISO 9001 + 14001. Canton, Michigan, USA.
Demand Outran the Supply Chain. Boards Are Single-Sourced. Capacity Is Spoken For.
Data center buildouts are growing faster than the equipment supply chain behind them. The OEMs supplying switchgear, busway, UPS, coolant distribution units, and monitoring hardware are running full — and the control assemblies inside their products often come from one supplier with no qualified backup.
Single-Sourced Control Assemblies
A PDU, UPS, or CDU is only as available as its controller. When that assembly comes from one line at one supplier, every schedule downstream inherits the risk — and procurement teams are now being asked to qualify a second source before the next build cycle, not after it.
Capacity Is Spoken For
The largest EMS providers are absorbing server and rack volume. Mid-volume infrastructure assemblies — a few thousand a month, with box build and harness attached — struggle to get a slot. OEMs need a partner who will dedicate a cell to their product and hold it.
Sensors and Leak Detection Need a Cleaner Room
Flow and temperature sensor assemblies, leak-detection harnesses, and high-reliability monitoring modules don't belong on a general assembly floor. Contamination control, ESD discipline, and process documentation matter more the closer the part sits to the coolant loop.
A Second Source That Is Already Running
Lotus runs a 300,000 sq. ft. contract manufacturing facility in Canton, Michigan, USA, under ISO 9001:2015 and ISO 14001:2015. For data center infrastructure OEMs, that means control-board box build and enclosure integration for power distribution and cooling equipment, harness and sensor assembly for the monitoring layer, functional test to your procedure, and consigned inventory staged against your build schedule — from a supplier that has spent 31 years inside formal OEM qualification programs.
The sensitive portions — leak-detection harnesses, flow and temperature sensor assemblies, high-reliability monitoring modules — can run in 20,000+ sq. ft. of ISO Class 6 and Class 7 cleanroom. And when units come back from the field, the same team runs component-level depot repair with failure data fed back to your engineers. If you need a qualified second source that behaves like a first source, the infrastructure is already in place.

From Second-Source Qualification to Field Return
One Canton, Michigan, USA facility runs the full lifecycle for data center infrastructure hardware — supplier qualification, box build and integration, harness and sensor assembly, test, consigned inventory, and depot repair for the units that come back.
Supplier Qualification & NPI
We register on your supplier portal, work from your supplier quality manual, and run first articles against your acceptance criteria. Pre-production builds validate the process before you commit volume.
Control-Board Box Build & Integration
Enclosure integration, wiring, and final assembly for PDU, STS, UPS, switchgear, and CDU controllers — built to your documentation and approved vendor list, with lot traceability on every unit.
Sensor, Harness & Leak-Detection Assembly
Flow and temperature sensor assemblies, leak-detection harnesses, and matched cable kits — built in ISO Class 6 and Class 7 cleanroom space when the specification calls for it.
Test & Documentation
Functional and electrical test to your procedure, dielectric and hi-pot where required, with per-unit records that feed your UL and IEC documentation packages. You hold the listing; we build to the listed design and prove it.
Consigned Inventory & Staged Release
Buffer stock and consigned component inventory held in our same-facility 3PL warehouse, kitted and released against your build schedule. 12 truck wells for inbound components and outbound assemblies.
Depot Repair for Field Returns
Failed controllers, PDU and UPS monitoring modules, and CDU electronics route to our depot for component-level diagnosis, repair, and return — with root-cause data fed back to your engineering team.
A Day's Drive From
the Midwest Buildout
Canton, Michigan, USA sits at the center of the Great Lakes industrial corridor — within a day’s truck of the Ohio, Indiana, Illinois, and Pennsylvania plants where much of the country’s switchgear, busway, UPS, and thermal equipment is engineered and built, and within reach of the Midwest and Northeast data center campuses those OEMs are supplying.
For infrastructure OEMs qualifying a domestic second source, the address does work: shorter freight, same-week engineering visits, and US-built assemblies that support your domestic-content documentation. Backed by warehousing and depot repair in the same building.
- Canton, Michigan, USA — central to Midwest and Northeast hyperscale and colocation builds
- Next-day truck to Ohio, Indiana, Illinois, and western Pennsylvania OEM plants
- 12 truck wells and 300,000 sq. ft. for consigned inventory and staged release
- US-built assemblies support domestic-content documentation
The OEMs behind data center power and cooling need a second source that behaves like a first source — qualified, dedicated, documented, and already running. That is what 31 years of contract manufacturing and depot discipline under one roof look like.
Same facility. Same rigor. Built for the buildout.
Dedicated Capacity, Not a Slot in the Queue
A cell with your product name on it, staffed and held for your schedule — with buffer inventory in the same building so a demand spike doesn't restart the lead-time clock.
Cleanroom for the Sensitive Parts
20,000+ sq. ft. of ISO Class 6 and Class 7 cleanroom for leak-detection harnesses, sensor assemblies, and high-reliability monitoring modules — the parts of a cooling loop where contamination becomes a field failure.
Domestic, Certified, Auditable
ISO 9001:2015 + ISO 14001:2015, NMSDC-certified MBE, AS9100 certification in progress. Formal supplier-qualification programs audit against process discipline — ours is documented and running in one Canton, Michigan, USA facility.

Lotus builds the electrical and thermal infrastructure assemblies around the racks, for the OEMs that supply them — not for data center operators directly. That includes control-board box build and enclosure integration for busway tap boxes, rack PDUs, static transfer switches, UPS monitoring, and switchgear controls; CDU controller box build and pump / valve control assemblies for liquid cooling; leak-detection harnesses and flow / temperature sensor assemblies; and DCIM sensor nodes, EPMS / BMS gateways, and matched cable kits.
No. Server, GPU, and rack integration is high-volume ODM territory. Lotus focuses on the mid-volume control, sensing, and power-distribution assemblies that the infrastructure OEMs need a qualified second source for — typically a few hundred to a few thousand units a month with box build and harness attached.
Yes. That is the most common starting point. We work from your drawings, BOM, approved vendor list, and test procedure, register on your supplier portal, and run first articles and a pre-production build against your acceptance criteria before you commit volume. Dedicated line capacity and buffer inventory are available so the second source behaves like a first source.
No. The OEM holds the listing — UL 508A, UL 62368, UL 1973, or the applicable IEC standard. Lotus builds to the listed design, follows your controlled documentation, and provides the per-unit test and traceability records that feed your compliance file. We do not self-certify or claim listings for customer products.
Yes. Lotus operates 20,000+ sq. ft. of ISO Class 6 and ISO Class 7 cleanroom in Canton, Michigan, USA. Leak-detection harnesses, flow and temperature sensor assemblies, and high-reliability monitoring modules can run in controlled space when the specification calls for it; standard box build and harness work runs on the main floor.
Yes, through our Energy Storage & Batteries program — BMS controller box build, cell-monitoring units, contactor and pre-charge assemblies, and enclosure box build for the battery storage that backs a campus grid connection. Class 9 hazmat handling and reverse logistics are in the same facility.
Yes. Failed controllers, PDU and UPS monitoring modules, and CDU electronics route to our depot for component-level diagnosis, repair, and return under the same ISO 9001 and ISO 14001 processes as the assembly floor — with root-cause and failure data fed back to your engineering team.
