What Stillwell-Hansen does
Stillwell-Hansen is a privately held manufacturers' representative and value-added technical services firm headquartered in Edison, New Jersey, founded in 1969. Operating from a 26,000 square foot facility in Raritan Center since 1992, the firm holds exclusive rights as the only authorized Vertiv sales and service representative across 12 northern New Jersey counties, functioning as an extension of its manufacturing partners rather than as an independent product company. Leadership has remained within the founding Stillwell family: Carol Stillwell, who joined as a secretary in 1969, has served as President and CEO since 1996 following Paul Hansen's retirement, with Glenn Pabst as Vice President.
The company's portfolio centers on the Vertiv critical infrastructure stack: Liebert uninterruptible power supplies (including lithium-ion variants), power distribution units, racks and enclosures, Liebert iCOM thermal management, Liebert XDU coolant distribution units for liquid cooling (operating from -20°C to +70°C), and the SmartMod, SmartMod Max, SmartMod Combo, and MegaMod lines of prefabricated modular data centers. Complementing Vertiv are Condair humidification and dehumidification systems, Systecon modular central utility plants with Wire-to-Water Efficiency optimization (a methodology developed in 1984), fire detection and suppression from Kidde, Fike, and VESDA by Xtralis, and Systecon NIMBUS fluid cooling for industrial and healthcare retrofits. Vertical coverage spans data centers, healthcare facilities, government, manufacturing, commercial buildings, growhouses, indoor pools, pharmaceutical, and printing applications.
Stillwell-Hansen generates revenue through two streams: manufacturer commissions on equipment sales across its 7 divisions (HVAC Sales, SH Datasite Protection, SH Technical Services, SH Technical Parts, IT Solutions, SH Technical Safety & Compliance Solutions, and Liebert/Emerson Sales), and service revenue from a dedicated technical service department performing startup, troubleshooting, and repair work, supported by a multi-million dollar parts inventory. Go-to-market is direct field sales led by technically proficient staff averaging 25+ years of experience, targeting enterprise customers across its exclusive northern New Jersey territory. The firm is privately held with no external capital, no M&A activity, no app or API surface, and no disclosed financials.

Stillwell-Hansen competitors and assessment
Company assessmentBroad incumbents
- Vertiv: Vertiv is the global manufacturer of Liebert UPS, thermal management, and modular data center systems that Stillwell-Hansen represents. They are comparable because Vertiv operates its own direct sales force alongside rep partners, and any shift in their channel strategy directly affects Stillwell-Hansen's franchise.
- Eaton: Eaton manufactures UPS systems, power distribution, and electrical infrastructure used in data centers and industrial facilities. They are comparable because their equipment directly competes with Vertiv in the same critical power categories that Stillwell-Hansen sells and services.
- ABB: ABB provides power protection, distribution, and industrial automation equipment including UPS systems and switchgear for mission-critical facilities. They are comparable because they compete in the same critical power category and operate through their own rep and integrator channels overlapping Stillwell-Hansen's customer base.
- Schneider Electric: Schneider Electric is a global manufacturer of UPS, PDU, and cooling products that competes head-to-head with Vertiv in the data center critical infrastructure market. They are comparable because their products are frequently substituted for Vertiv systems in the same customer RFPs that Stillwell-Hansen competes for.
Emerging players
- Chatsworth Products (CPI): Chatsworth Products manufactures cabinets, racks, cable management, and power products for data centers and telecom. They are comparable because they offer alternative rack and enclosure solutions to those represented by Stillwell-Hansen in customer specifications.
- nVent: nVent manufactures enclosures, racks, and electrical connection and protection solutions for industrial and data center applications. They are comparable because they offer competing infrastructure products that frequently appear in the same RFPs as the Vertiv solutions Stillwell-Hansen represents.
- Rittal: Rittal manufactures IT enclosures, racks, and power distribution products for data centers and industrial applications. They are comparable because their enclosures and PDU products compete with the Vertiv racks and PDU portfolio that Stillwell-Hansen distributes.
- Stulz: Stulz is a specialist manufacturer of precision air conditioning and liquid cooling systems for data centers. They are comparable because their cooling products compete with Vertiv's Liebert thermal management line that Stillwell-Hansen distributes in northern New Jersey.
Others
- Graybar: Graybar is a leading North American distributor of electrical, communications, and data networking products including UPS, PDU, and infrastructure equipment. They are comparable because they distribute many of the same product categories to overlapping enterprise and data center customers through a broad-line distribution model.
- WESCO International: WESCO International (including Anixter) is a major electrical, communications, and utility distributor that resells critical infrastructure products to data center and industrial customers. They are comparable because they sell overlapping product lines through a different distribution model and compete for the same end customers.
