What PyroSafe Ltd does

PyroSafe Ltd is the brand name under which Vapour Flow Limited (Company Number 04950095, incorporated 2003 in England and Wales) designs, manufactures, and supplies smoke and fire protection ventilation products from its headquarters at Henley Business Centre, Newtown Road, Henley-on-Thames, UK. The company's product portfolio centres on the PyroDuet, an automatic dual smoke and fire protection valve for communal ventilation systems certified EI90S under EN13501, featuring servo motor operation, a 700°C spring melt fail-safe, humidity-compensated smoke detection, temperature rate-of-rise detection, and a 7-layer dynamic valve seal rated for 90 minutes. Supporting products include the PyroDuetFan 80 smart extraction vent with ionisation smoke detection and app-enabled remote testing, the PyroSafe Vent smoke protection smart vent, the AutoFlow self-balancing mechanical air flow valve that operates without electrical power, and a range of five ductwork adaptors for varied installation configurations.

The underlying technology rests on electromechanical sensing and actuation — smoke and temperature sensors trigger servo-operated valves that shut down ventilation ports, with mechanical fail-safes ensuring closure even at extreme temperatures. The PyroDuetFan 80 adds Bluetooth/app connectivity for remote testing and data logging, while the AutoFlow valve uses purely mechanical dynamic pressure balancing. Products conform to multiple British and European standards (BS5446-1:2000, EN54-4:2000, BS5446-2:2000, BS EN 14604:2005, BS 5839-6:2004, BS476:Part22 20:1987) and adhere to the WEEE directive. A bespoke service covers site survey, custom product design, build, and installation by PyroSafe's own certified technicians.

PyroSafe generates revenue through one-time hardware sales priced per unit (PyroDuet £675, PyroDuetFan 80 £730, AutoFlow £160, adaptors £22–£108) and professional installation services. The go-to-market combines direct B2B sales to UK housing associations, local authorities, and private sector builders with direct-to-consumer e-commerce through the pyrosafevent.com storefront operated by Vapour Flow Limited as captive retailer and distributor. The company employs 11–50 staff, operates exclusively in the UK market, and has been active in the smoke protection ventilation industry for several decades with involvement in the development of features now considered mainstream in the sector.
