What Ziztel does

Ziztel Limited is a UK-based designer and manufacturer of mission-critical communications systems engineered for hazardous industrial and marine environments. Founded in 2010 by Nat Dickens and headquartered in Nottingham, the company specializes in Public Address & General Alarm (PAGA) systems under the flagship ZEST platform, the Zizcam range of explosion-proof CCTV and thermal imaging cameras, Drillers and Marine talkback intercoms, acoustic hoods, and addressable beacons. Core technology is built around A+B fully redundant architecture, a proprietary hard-core processor designed to eliminate cyber-attack risk and boot delays, and Class G amplification delivering up to 18kW in a single 19-inch rack with a -90dB signal-to-noise ratio. Products are certified to ATEX, IECEx, Zone 1 IIC, ABS Type Approval, and IMO SOLAS standards for use in potentially explosive atmospheres and life-safety applications.

The company operates a project-based business model with quote-only, multi-year contracts that bundle bespoke engineering, detailed design, factory acceptance testing, site commissioning, and long-term maintenance. Go-to-market is almost exclusively indirect through large international Telecoms and Security Systems Integrators, with Ziztel's role positioned as the specialist OEM technology partner specified into mega-projects. Pricing is not publicly disclosed and is configured per project scope, certification requirements, and redundancy architecture. Customers are concentrated in Oil & Gas (offshore platforms, refineries, petrochemical plants, pipelines, FPSOs, LNG), with adjacent verticals in Renewable Energy (offshore wind), Marine (cruise ships, naval frigates, submarines), Defence, and Nuclear power generation.

The company employs 11-50 staff, maintains installations in 35+ countries, and is privately held with founder ownership and no disclosed institutional investment. Revenue is not publicly disclosed but is generated through discrete multi-million dollar mega-project deliveries to enterprise counterparties such as Coral FLNG, China Petroleum Pipeline (Iraq), Khazzan Gas (Oman), TANAP Pipeline (Turkey), and YPFB Bolivia, supplemented by recurring maintenance agreements and addressable aftermarket sales.
