USystems Ltd

What USystems Ltd does

USystems Ltd is a Bedford, UK-headquartered designer and manufacturer of precision data center cooling and infrastructure solutions, founded in 2007. Its core offering is the ColdLogik Air Assisted Liquid Cooling (AALC) product line, which encompasses rear door heat exchangers (RDHx) in active and passive variants (CL20, CL21, CL23) capable of cooling 0.1kW to 204kW per cabinet, precision in-row coolers (CL80 series) for aisle containment, and a Cooling Distribution Unit (CDU) for primary/secondary fluid circuit separation. The proprietary ColdLogik Management System (CMS) provides closed-loop adaptive control over fluid volume and fan speed based on three-zone temperature sensing. The portfolio is rounded out by the USpace rack and containment brand (4210, 5210, Soundproof Rack, and horizontal/vertical aisle containment) and the EDGE-3 Soundproof Micro Data Center for plug-and-play edge deployments.

The company sells primarily through direct enterprise field sales supplemented by channel partners including Mayflex (UK distribution, August 2021) and Rahi Systems (global system integration, August 2021), with pricing on a quote-based engineering-to-order model and a Fast Track product line delivering standard configurations in 4-6 weeks. Customer segments span enterprise data centers, HPC and AI facilities, and edge/micro data center use cases, with named customers across education and research (Cambridge University, CERN), automotive (Jaguar Land Rover), technology (ARM Holdings, Sony Europe, Bulk Data Centers), financial services (PayPoint), insurance (Chubb Insurance), energy (Dong Energy), telecommunications (Zajil), and manufacturing (STIHL). USystems Ltd was acquired by Legrand Group in July 2022 and operates as a wholly-owned subsidiary, retaining the USystems and ColdLogik brand identities.

Core offering

USystems designs, manufactures, and sells precision data center cooling and infrastructure hardware under the ColdLogik, USpace, and EDGE brands. The portfolio spans Air Assisted Liquid Cooling (AALC) rear door heat exchangers (CL20, CL21, CL23), in-row precision coolers (CL80), cooling distribution units (CDU), server racks and aisle containment, and self-contained micro data centers (EDGE-3).

Product overview

USystems Ltd offers a comprehensive portfolio of data center cooling and infrastructure products under the ColdLogik and USpace brands. The ColdLogik line includes Rear Door Heat Exchangers (RDHx) in three variants (CL20, CL21, CL23), InRow Coolers (CL80 series), and a Cooling Distribution Unit (CDU), all managed by the proprietary ColdLogik Management System. The USpace brand encompasses server cabinets (4210, 5210, Soundproof Rack) and aisle containment solutions (Horizontal, Vertical). Additionally, the EDGE-3 Soundproof MDC provides micro data center solutions. Together, these products address data center thermal management from rack-level cooling to full facility containment, serving both retrofits and new build environments with scalable cooling capacities ranging from 0.1kW to 200kW per cabinet.

Direct peers

• Vertiv: Vertiv is the most direct competitor in data center thermal management, offering rear door heat exchangers, in-row precision cooling, and CRAC/CRAH systems to enterprise and hyperscale data centers globally. Both companies target the same cooling RFPs with overlapping product architectures.
• CoolIT Systems: CoolIT Systems specializes in liquid cooling solutions (cold plates, CDUs, rack manifolds) for high-density AI and HPC data centers. It targets the same high-density cooling opportunity as USystems' CL23 and ColdLogik CDU and competes in AI workload RFPs.
• Asetek: Asetek provides direct liquid cooling (DLC) systems for data centers, gaming and high-performance computing. Its rack-mounted and CDU products compete with USystems in the high-density liquid cooling category serving HPC and enterprise AI.
• Boyd (formerly Allied): Boyd's data center division (incorporating the former Aavid and Allied Thermal brands) offers rear door heat exchangers, cold plates and liquid cooling solutions. It is one of the closest direct competitors to ColdLogik RDHx in both retrofit and new-build segments.

Broad incumbents

• Schneider Electric: Schneider Electric's IT division offers Uniflair precision cooling, in-row coolers and chilled-water systems alongside a much broader data center infrastructure portfolio (UPS, racks, software). It competes head-on with USystems in cooling while bundling wider solutions for enterprise customers.
• Rittal: Rittal is a major enclosure and data center infrastructure vendor offering liquid cooling packages (LCP), in-row cooling and IT racks that compete with USystems' ColdLogik and USpace product lines, particularly in European enterprise accounts.
• Stulz: Stulz is a precision cooling specialist offering CyberAir, CWK and InRow precision air conditioning for data centers. It overlaps directly with USystems' InRow precision cooler line and competes on similar enterprise and colocation tenders.
• nVent Electric: nVent offers enclosures and data center cooling solutions (including liquid cooling acquisitions) within a broader electrical connection and protection portfolio. It overlaps with USystems on rack-level and enclosure-level cooling products.
• Munters: Munters provides data center cooling and air treatment solutions, including evaporative cooling and adiabatic systems that compete with USystems on energy-efficient data center cooling for hyperscale and colocation facilities.

Emerging players

• ZutaCore: ZutaCore is an emerging player offering hyper-efficient direct liquid cooling (two-phase cooling) for high-density AI and HPC workloads. It targets a similar niche to USystems' AALC at the cutting edge of high-density thermal management.
