Commercial kitchen recirculation units — FAQs

What is a commercial kitchen recirculation unit?

A commercial kitchen recirculation unit is a ductless extraction system that captures grease, smoke and odour from cooking, filters the air through multiple stages, and returns clean air to the room instead of ducting it outside. It lets you run a commercial kitchen where external ducting isn't practical.

Do recirculation units need ducting?

No. CK ReCirc™ units are fully ductless and require no external ducting to atmosphere, which makes them ideal for listed buildings, basements, upper floors and sites with planning restrictions.

How do CK ReCirc™ units remove grease and smoke?

Each unit uses 5 stages of filtration to remove grease, odour and smoke, including Franke Cascade™ high-efficiency grease filters fitted in the extract hood as standard.

What sizes are available?

CK ReCirc™ units come in 8 standard sizes from 1000 mm up to 6000 mm wide, with bespoke builds and island canopy options available to any required size.

Can recirculation units be used with gas appliances?

CK ReCirc™ units are designed for use above electrical cooking appliances. If you cook on gas, talk to our team about the right ventilation solution and any gas interlock requirements.

Where can recirculation units be installed?

They are used in airports, coffee bars, restaurants, public houses, shopping centres, sports stadiums, temporary catering canteens and listed buildings — anywhere a conventional ducted system is difficult or not permitted.
