PRODUCT INFORMATION

The reticulation system offers all of the normal Coanda features as well as the ability to reticulate up to 40% of the airstream reducing duct size etc.

Coanda hoods are manufactured completely from AISI 304 1.2mm No 4 finish Stainless Steel.

Supply and reticulated air are distributed via Coanda face of hood at low velocity ensuring maximum capture while mitigating breach.

Treat and reticulate up to 40% of the airstream when only minimal external extraction is available.

With our unique suite of treatment options reticulation over a standard cooking line is now a reality.

Re-circulating Hoods draw in steam and odour saturated air through the filters and ozone system returning part of the treated air into the kitchen which reduces overall exhaust requirements.

ADVANTAGES

Ideal for kitchen environments where a typical ducted system is impractical or uneconomical, the Coanda Recirculating Hood is complete with fans and a multi-stage filtration process.

The filtration process consists of Coil pack filters, ozonation and disposable scrubbing filters which absorb the last of the particulate enabling up to reticulate part of the airstream.

The supply air follows the Coanda face, corralling exhaust fumes into the filtration process.

The result is a safe and clean discharge with minimal odour.

CASE STUDY

Through the use of Coanda reticulation technology at El Camino Brisbane we were able to convert a ground floor coffee shop in a multi-level building to a Mexican restaurant utilising the same ducting.

The original ducting provided limited airflow capacity, with Coanda reticulation technology we were able to utilise the same ducts with over 1,000MJ of cooking!

The result was that by not having to replace 5 stories of ductwork that ran through multiple tenancies we saved the owner over $200,000 in base build costs and months of construction time.

CONSTRUCTION

Coanda Hoods are manufactured from ASI304 1.2mm no 4 finish S/S.
Unique Coanda “Curve” M/U air plenum.
Led strip lighting.
Front cup coil pack filters.
Removable louvred makeup air deflectors.
Corona Discharge Ozone generator, including piping kit. Generator comes with ozone sensors and alarms for safe use in a ventilated room.
Custom dimensions to suit each application.
Coil pack filters – UL and NSF classified. These Filters remove up to 80% of particles with a size of 5 microns or above thus removing most odour and grease from the discharge.
Disposable scrubbing filters to adsorb 90% of the smaller particle sizes of grease.
Ready to install” standard delivery packages with lighting as well as commissioning ports for field balancing.

CERTIFICATION

Coanda hoods are certified by an independent specialist engineering firm providing certainty of performance.

To meet code requirements, the kitchen room still requires an air change of 5L/s/sqm. An exhaust port with 100Pa external static allows the discharge to provide this exhaust or it can be separate.
