Project in Dishforth

We received a call from our long-standing client, asking us to assist them with the ongoing problem with the kitchen ventilation system at a site in Dishforth. Our initial survey noted several issues with the current setup and the brief was to repair the system, retaining as much as possible/practicable to reduce cost. This site hadn’t been touched in over 20 years; the kitchen extract system had a number of reclaim coils, along with canopy filters which hadn’t been cleaned or replaced. Below was the coil we removed and it was shocking to see that the little 450mm diameter cased extract fan was still operating!

Within our scope, we replaced the existing kitchen canopy grease filter assembly with a new full length assembly, housing stainless steel baffle grease filters. This had to be designed to fit the existing canopy, meaning we had to match the sloping sides. Thankfully, we worked together with our client who designed the existing equipment around the existing canopy footprints, meaning we could maintain the required overhangs to the equipment and avoiding the need (and added expense) for a kitchen canopy extension. The kitchen extract system also received a complete upgrade; we utilised the majority of the existing 20m length of extract ductwork and then we installed a new centrifugal extract fan to suit the required air volume and system pressures, and we must say the site personnel were thrilled with the performance of the upgraded system, even if we do say so ourselves! To put it into perspective, the original system couldn’t hold a piece of tissue, but following our works, it can now hold an entire roll! 😊

The kitchen ventilation system on site also lacked mechanical air input and we needed to include some form of fresh air input to meet the required regulations. The simplest solution was to duct from the outside wall and distribute this into the space. We manufactured the ductwork from stainless steel meaning we could house all the internal joints/brackets, resulting in a clean finish.

We installed and commissioned the new gas interlock system and recorded all the air volumes, confirming the system meets site requirements. We even left a little cheat sheet on full view, in case the team on site had difficulty operating the fans! 

All in all, another successful project and one which has saved the end-user money as well as reducing the impact to the environment by reusing existing products.

As well as designing brand new kitchen ventilation systems, Trivent Ltd have been upgrading existing systems, as part of the service that we offer, since 1980. We will always try and reuse what we can on site, for both sustainability and to try and save you money. Contact us to see how we can help you upgrade your existing kitchen ventilation system.
