What we manufacture
Our manufacturing covers the key components that determine system performance:
- Air handling unitscustom-built to the design specification with heating coils, cooling coils, filters, fans and controls integrated
- Balanced JET induction systemsspiral wound ductwork with computer-calculated nozzles for precise air distribution
- Packaged plant unitsheat pump and chiller packages configured for specific applications
- Control panelspurpose-built control panels for system automation and BMS integration
Bespoke air handling units, designed in-house
Why in-house manufacturing matters
When we design a system, we know it can be built — because we build it ourselves. There's no gap between what the designer specifies and what arrives on site. If the design requires a non-standard configuration, unusual dimensions, or specific performance characteristics, we engineer the solution rather than compromise the design to fit available products.
Quality and traceability
Every unit we manufacture is tested before leaving our facility in line with our ISO 9001 quality management system. Performance data is recorded and forms part of the project documentation. When the equipment arrives on site, our installation teams know exactly what they're working with — because the same organisation designed, built, and will install it.
Retrofit and replacement
We also manufacture replacement components and upgrade equipment for existing installations — whether originally supplied by us or by other manufacturers. If your current equipment is reaching end of life, we can engineer a modern replacement that integrates with your existing infrastructure.
Our approach
Design specification — equipment requirements defined from the system design
Engineering review — manufacturing feasibility, material selection, build sequence
Fabrication — air handling units, ductwork and nozzle systems built to specification
Quality control — performance testing before dispatch to site
Delivery and coordination — logistics planning for large-scale equipment delivery
Why Jet Environmental
- Purpose built to your specification
- Complete control over quality from design through to installation
- Lead times to suit your project programme
- Integrated with our design process — no specification translation errors
- Modifications and upgrades available through the same team that built the original
