Sigma Engineering Product Design

What Sigma Engineering Product Design does

Sigma Engineering Product Design Ltd is a privately held Scottish limited company, founded in 2002 and headquartered in Irvine, Ayrshire, that designs, manufactures and installs commercial and industrial ventilation systems. The company serves Edinburgh, Glasgow and the Central Belt of Scotland as its core territory, with UK-wide project delivery undertaken on request. Its end markets span hospitality (restaurants, hotels, golf clubs, cafes), manufacturing and industrial, healthcare (NHS authorities and private clinics), food production, commercial real estate, facilities management and housing associations.

The product portfolio centers on three proprietary platforms: the patented Sigma Heat Recovery Ventilation (HRV) counter-flow system for dirty airstreams; the SigmaBlackbox EC fan range built on Ziehl-Abegg motors; and the Sigma360 Filtration Ventilation System, launched in November 2022, which integrates natural ventilation, extraction, supply/makeup air and 3-stage filtration including H14 HEPA, with CO2-driven demand control. These are complemented by kitchen extract systems and bespoke 304 stainless steel canopies, LEV design, manufacture and HSG258/COSHH-aligned testing and certification, fan wall systems, solid fuel extract, anti-vandal weather louvres, and contract manufacturing of ductwork and water-jet-cut components.

Sigma operates a project-based, consultative B2B go-to-market: every system is bespoke, priced via quote after site assessment, and delivered through a turnkey design-manufacture-install model, with recurring revenue from maintenance contracts, performance verification visits, 24/7 callout and LEV testing. The company monetizes across one-time equipment and installation sales, professional services (consultancy and LEV certification), managed services (maintenance and aftercare) and component/ancillary supply. Its competitive positioning rests on patented HRV IP, in-house design and manufacturing capability, and deep UK regulatory compliance across CHAS, Constructionline Silver, CSCS, BESA, DW/172, DW/144, TR/19, HSG258 and COSHH.
