RAH – Reco-Air by Halton – Recirculating kitchen extract unit (CE)
No requirement for route to atmosphere for all electric catering equipment
Reco-Air by Halton RAH recirculating units work at the heart of a kitchen ventilation system serving all electric catering equipment and achieving complete recirculation of exhaust air with no requirement for ductwork to outside.
RAH units’ highly efficient filter technology removes particulates and odours. The processed air is independently certified as clean to be re-introduced as supply air.

Overview
RAH units eliminate long ductwork to outside when they become too costly or when they simply are impossible to install. Technical constraints on buildings’ structure, restrictions linked to listed activities or historic sites, co-ownerships opposed to the degradation of the facades aesthetic or to odor nuisance risk… all these challenges can easily be overcome with recirculation units.
In addition to providing opportunities to install kitchen operations in previously unfeasible locations, RAH units significantly reduce fire risk. They also simplify planning procedures.
Globally cost effective
- RAH units reduce CAPEX investment. They eliminate the costly fire-rated duct work to atmosphere thus reducing the construction and installation costs.
- They also reduce the utility usage and plant requirement with a compact design, an ease of assembly and flat pack options.
- RAH units enable establishing a restaurant wherever you chose i.e. where it is of most value, whatever the technical or environmental challenges.
- Traditional extract duct work requires regular specialist cleaning. RAH units significantly reduce maintenance regimes when accessing duct systems and plant is difficult and time consuming.
- When combined with Halton’s Capture Jet™ hoods or ventilated ceiling, the installation and operating costs are even more reduced. They reach the lowest possible level when M.A.R.V.E.L. optimization airflow technology is also used.
- RAH units are a cost efficient alternative to traditional extract when there’s no easy route to atmosphere.
Reduced fire risk and emissions control
- RAH units significantly reduce fire risk by eliminating ductwork to outside and suppressing grease deposits after the unit.
- RAH units reduce the need to pierce buildings’ fire compartments.
- For high risk operational environments with the most stringent fire safety requirement, RAH units can be in addition installed in their own fire compartment. Whether located in or outside the main fire compartment, wherever a fire occurs, there’s no risk RAH units contributing to the fire spreading.
- The contaminants produced by commercial kitchens are no longer expelled to outside thus removing the risk of nuisance on the neighbourhood and possible legal actions.
Distant monitoring
- Equipped with Halton Connect IoT (Internet of Things platform) platform with advanced 24/7 distant monitoring capabilities.
- Highest value of ownership thanks to Halton Connect & Care smart services offering.
Flexible at many respects
- RAH units can be located internally or externally, adjacent to or remote from the kitchen. The unit can be hung within ceiling voids giving flexibility to equipment layout and also eliminating the requirement for certain planning processes.
- RAH units enables adding cooking appliances in existing kitchens without the need to deeply modify the ventilation system.
- RAH units facilitate internal layout flexibility. They are easily retro-fitted or relocated.

Principles of operation
Cooling down the return air
After RecoAir unit, the return air is a similar temperature to that extracted and needs to be cooled down before being blown back into the kitchen.
– Spot cooling i.e. fan coil units within the kitchen space;
– Chilled water coil or DX refrigerant cooling coil installed on the return air ductwork etc…
Air balance and “hygienic” fresh air
Depending on local regulations, a minimum amount of fresh air has to be blown inside the kitchen.
To keep the kitchen under negative pressure, and depending on the kitchen configuration, additional exhaust points can be installed or a small “discharge” branch can be installed on the return air ductwork.
Hybrid solution
RecoAir units can be used to complement traditional Air Handling Units in some specific configuration or when it is not possible to use the required duct sections for the design total airflows.
About Halton Connect & Care
Halton Connect is a state-of-the-art IoT (Internet of Things) platform whose core is an advanced cloud-based portal. It enables 24/7 remote monitoring of the solutions designed by Halton. It allows access to important and useful information along with powerful data analytics to the end users. It also provides crucial information to our engineers. In return, they can remotely and safely control all systems and their settings when required.
This digital “two directions” technology opens the way to Premium Services that are vital to keep the performance of the systems and technologies at the initial design level and during the entire lifecycle. Even better! They enable continuous optimisation of your systems, resulting in even lower operating costs.
