Vertiv
Critical power, thermal management and IT infrastructure
Vertiv designs and manufactures the equipment that keeps data centers, communication networks and critical facilities running — precision cooling, uninterruptible power, power distribution, racks and monitoring. Its Liebert, Geist, NetSure and Great Lakes brands cover most of what sits between the utility feed and the load.
What we carry
- Liebert precision cooling and thermal management
- Liebert uninterruptible power supplies
- Static and static bus transfer switches
- Vertiv racks and containment, including Great Lakes Data Racks & Cabinets
- Liebert busway, powerbars and modular power distribution
- Geist rack PDUs and rack transfer switches
- Remote power panels and packaged power distribution
- NetSure DC power systems
- Battery monitoring and testing, continuing under Vertiv branding (formerly Alber)
- Vertiv monitoring and management software
Access and Vertiv
Vertiv is the largest line Access represents, and the one most of our service work is built around. We specify it, install it, stock parts for it and maintain it across Northeastern Wisconsin and Michigan’s Upper Peninsula — which means the people sizing your system are the people who will be on site when it needs attention. Vertiv completed its acquisition of Great Lakes Data Racks & Cabinets in August 2025, so Great Lakes enclosures, open frame racks and aisle containment now come through the same line, the same quote and the same service relationship as the cooling and power around them.
Vertiv services
Vertiv equipment is sold with a service capability behind it, and that capability is a large part of what Access delivers. Access coordinates and delivers this work through our own technicians and Vertiv’s factory service organization, and stays accountable for the outcome either way.
- Real-time remote monitoring
- Preventive maintenance programs
- Condition-based maintenance
- Remote management and remote diagnostics
- Lifecycle and lifecycle-extension services
High Voltage Maintenance — electrical power management services
High Voltage Maintenance is a Vertiv company, and it covers the electrical testing and engineering side of a critical facility: proving the protection scheme is right on paper, then proving the gear actually behaves that way in the field.
- Arc flash studies
- Protective device coordination studies
- Short-circuit and coordination analysis
- NETA acceptance and maintenance testing
- Infrared scanning and electrical maintenance
Uninterruptible Power Supplies
UPS systems from single-rack to multi-megawatt — sized, installed and maintained so the load never sees the blip.
Busway & Powerbars
Overhead and modular busway that lets a data hall change shape without an electrician rebuilding the branch circuits.
Power Distribution
PDUs, remote power panels and packaged distribution from the UPS output down to the rack.
Precision Cooling & Thermal Management
Computer room cooling that holds tight tolerances continuously, rather than comfort cooling asked to do a job it was not built for.
Racks & Containment
Enclosures and aisle containment that make cooling work as designed instead of fighting itself.
Emergency Lighting Inverters
Centralized emergency lighting power — code-compliant egress lighting without a battery pack in every fixture.
Integrated Solutions
Pre-engineered power, cooling and rack in one enclosure — a data room delivered rather than assembled.
Switchgear, Panelboards & Subpanels
Distribution gear from the service entrance down to the subpanel, specified as part of the protection scheme rather than as a commodity.
