This installation features one of our recirculation extraction units, a system specifically engineered for environments where traditional ducting simply isn’t possible.
What is a Recirculation Unit?
A recirculation unit is a ductless extraction system that draws air through a multi‑stage filtration process — typically including grease, carbon and HEPA filters — before returning clean air back into the room. Because it does not require ducting to the outside, it is ideal for locations with:
- No available route for external ductwork
- Planning restrictions
- Structural limitations
- Confined or sensitive environments such as train stations, airports, shopping centres and listed buildings
Why It’s Useful for Chop Wok
Chop Wok operates fully automated wok cookers, which produce controlled, light‑to‑medium cooking vapours. This makes them perfectly suited to a recirculation system. The unit provides:
- Effective filtration for light cooking
- Compliance without external ducting
- A compact footprint ideal for small commercial spaces
- Fast installation with minimal disruption
It’s a practical, cost‑effective solution that allows Chop Wok to open in locations that would otherwise be impossible for traditional extraction systems.

Supporting Chop Wok’s National Growth
With installations already completed across multiple regions — and more franchise sites on the horizon — Chop Wok continues to rely on Canopy UK for dependable, space‑efficient extraction solutions that support their expansion into high‑traffic, high‑restriction locations.
Their South Central Train Station store is another example of how smart engineering and careful planning can transform even the smallest spaces into fully functioning commercial kitchens.
