What Alquist does

Alquist Consulting Ltd is a privately held UK technology company founded in 2003 and headquartered in Cambridge, England. The firm operates as a small (1–10 employee) consultancy and niche hardware/software vendor, split between IT infrastructure design services and a proprietary fibre-optic temperature monitoring product line.

The company's core technology is the Celsius system, a fibre-optic Distributed Temperature Sensing (DTS) platform that uses Raman back-scattering analysis to convert a standard 50/125 fibre-optic cable into a high-precision temperature sensor. A single cable can measure up to 20,000 points at 1m intervals with accuracy of 0.1°C (15-second sampling) to 0.01°C (longer sampling), covering a temperature range of −195°C to +750°C across cables up to 5km in length. The system is packaged as a standalone 19-inch rack-mounted unit with on-board PC. The accompanying DC-View software suite processes data into high-definition heat maps, originally developed for oil & gas pipeline and power transmission cable monitoring and now adapted for data centre environmental management.

Alquist monetises through four streams: (1) sale of Celsius hardware with DC-View software, (2) custom software development for industrial control problems, (3) IT infrastructure design and consultancy (delivered by BICSI RCDD-qualified consultants), and (4) technical writing and training services. The firm targets data centre operators (primary), oil & gas and power transmission utilities (primary), and IT infrastructure clients (secondary) via direct, consultative enterprise sales with custom quotations. The company is founder-led under Managing Director Andrew Jones, has no disclosed institutional investment, and has received regional industry awards from DatacenterDynamics (2010), BCS/Computing (2011), and Computer Weekly (2014).

Core offering

Alquist provides IT infrastructure consultancy, design and training services alongside its proprietary Celsius fibre-optic Distributed Temperature Sensing (DTS) hardware and DC-View monitoring software. The Celsius device continuously measures real-time temperatures along fibre-optic cables using Raman back-scattering, while DC-View translates those readings into alerts, visualizations, and analytics for operators of data centres, oil and gas assets, and power transmission infrastructure. Together, the offerings let mission-critical facility operators detect hot spots and asset stress without on-site calibration, batteries, or moving parts.

Product overview

Alquist offers a dual-product portfolio comprising Celsius (high definition temperature monitoring hardware) and DC-View (monitoring software). Celsius is a fibre-optic based temperature sensing system that measures thousands of points along a single cable using Raman back-scattering analysis. DC-View serves as the accompanying software platform that processes and visualises the temperature data, generating high definition heat maps. The products work together: Celsius hardware acquires temperature measurements while DC-View provides the user interface for data centre managers to monitor, analyse, and optimise operating temperatures.

Broad incumbents

• Rittal: Rittal supplies data centre enclosures, cooling, and environmental monitoring solutions for IT rooms. It addresses the same data centre cooling optimisation use case as Celsius.
• Schneider Electric: Schneider Electric provides EcoStruxure data centre infrastructure management and environmental/temperature sensing for white space, competing at the customer level with Alquist's data centre monitoring offering.
• CommScope: CommScope is a major provider of data centre structured cabling and infrastructure. Alquist's IT consultancy arm delivers BICSI RCDD-grade network and fibre infrastructure design competing in the same space.
• Schlumberger / SLB: SLB provides distributed temperature and fibre-optic sensing services for upstream oil & gas well and pipeline monitoring. It overlaps with Alquist's oil & gas pipeline temperature monitoring use case.
• Vertiv: Vertiv is a major data centre infrastructure provider offering thermal management, environmental monitoring, and DCIM software. Competes with Alquist's data centre temperature monitoring and DC-View use case, though via broader product portfolios rather than DTS fibre-optic.
• Siemens (Smart Infrastructure): Siemens Smart Infrastructure offers building and data centre environmental monitoring, including temperature sensing and energy management software. It overlaps with Alquist's data centre thermal monitoring use case as a larger incumbent.
• Yokogawa Electric: Yokogawa offers DTS-based temperature sensing solutions (e.g., DTSX series) for industrial process monitoring, oil & gas, and power. It is a much larger incumbent competing in the same DTS sensing category as Celsius.

Direct peers

• AP Sensing: AP Sensing is a leading manufacturer of fibre-optic Distributed Temperature Sensing (DTS) systems for power, oil & gas, and industrial monitoring. It is the closest direct competitor to Alquist's Celsius product, using similar Raman-based DTS technology.
• Bandweaver Technologies: Bandweaver is a global DTS and DAS fibre-optic sensing provider serving power transmission, oil & gas pipelines, and tunnel/infrastructure monitoring. It directly competes with Celsius in pipeline and cable temperature monitoring applications.
• NKT Photonics (formerly LIOS Technology): NKT Photonics acquired LIOS Technology, one of the original pioneers of fibre-optic DTS. They serve the same power cable, pipeline, and fire detection markets as Alquist's DC-View/Celsius line.
